Dry Spots & Drooping Plants: How to Troubleshoot a Failing Sprinkler Zone

A healthy, vibrant lawn and garden depend on consistent and even watering. But if you’ve started noticing dry patches in your grass or drooping plants in certain areas, you might be dealing with a failing sprinkler zone. Sprinkler systems are designed to deliver water in specific sections (zones), and when one zone isn’t performing, the problem can quickly spread to your landscaping’s health.

Here’s how to identify the problem — and what to do to get your sprinkler system back in top shape.

1. Spotting the Signs of a Failing Sprinkler Zone

Not all sprinkler problems affect the whole yard — some are zone-specific. Look out for these common symptoms:

  • Dry or brown spots in one section of your lawn while others stay green.

  • Wilted or drooping plants in flower beds connected to the same zone.

  • Uneven growth in certain areas.

  • Mushy or oversaturated spots in other parts of the same zone (indicating uneven coverage).

  • Sprinklers that don’t turn on when that zone is activated.

If you notice any of these issues, it’s time to test the zone in question.

2. Check the Zone’s Water Pressure

One of the most common reasons for a failing sprinkler zone is low water pressure. This can be caused by:

  • A partially closed valve.

  • A clogged nozzle or filter.

  • A leak in the zone’s piping.

Quick Fix:
Manually turn on the zone and check the spray pattern. If the water is weak or doesn’t reach its normal distance, start by inspecting the valves and filters for obstructions.

3. Inspect for Broken or Clogged Sprinkler Heads

A single damaged or clogged head can throw off the balance for the entire zone. Look for:

  • Sprinklers that aren’t spraying at all.

  • Heads that spray water in odd directions.

  • Dirt, grass, or debris is blocking the nozzle.

Quick Fix:
Clean the nozzles and filters, replace damaged heads, and adjust spray patterns to ensure even coverage.

4. Test the Zone’s Wiring and Controller

Sometimes the problem isn’t in the water flow at all — it’s in the electrical components. If the zone won’t activate, you may have:

  • A bad solenoid.

  • Loose wiring connections.

  • A faulty controller setting.

Quick Fix:
Check your irrigation controller to confirm the zone’s schedule is correct. If the schedule is fine, you may need to test or replace the solenoid.

5. Look for Underground Leaks

Undetected leaks can cause certain heads in the zone to lose pressure, leading to dry spots. Signs of a leak include:

  • Pooling water in the yard even when the sprinklers are off.

  • Soft or sunken patches in the lawn.

  • A noticeable increase in your water bill.

Quick Fix:
Leaks often require professional diagnosis and repair to avoid further damage to your system and landscaping.

6. When to Call in the Pros

While some zone issues can be fixed with a quick clean or adjustment, persistent dry spots or drooping plants often mean there’s a deeper problem. At American Irrigation Repair, we specialize in zone-specific troubleshooting and repairs that restore healthy, even watering across your entire property.

We can pinpoint leaks, replace faulty wiring, adjust spray coverage, and ensure your system runs efficiently — saving you water, money, and stress.

Regular system check-ups and seasonal tune-ups are the best way to avoid surprise sprinkler zone failures. Even a small issue can turn into a big problem if left unchecked, so act quickly when you spot early warning signs. Contact us today

How Much Do Home Sprinklers Cost to Install?

Last Modified 1/20/25

Austin, TX, gets less annual rainfall than the national average, meaning taking care of your landscaping can be tricky. Fortunately, landscaping sprinkler systems are a simple solution to ensure your yard gets the watering it needs. Of course, a natural question homeowners have is: How much do home sprinklers cost to install? The team at American Irrigation Repair is here to answer your questions about home sprinkler installation costs in 2025.

Sprinkler Systems Labor Installation Costs

According to our research, the average cost to install a home sprinkler system in the Austin area is between $3,500 and $5,200.  Custom and high-end and extensive sprinkler systems can cost upwards of $8,000 or more to install. 

Factors that Affect Home Sprinkler System Installation 

Several factors will affect the cost of installing a home sprinkler system such as those listed below. 

The Contractor

  • Unlicensed contractors or installers often do systems for a low price. Remember the quality, performance, and longevity of your system usually match the caliber of the contractor you hire.  
  • A contractor mustn’t be obtaining the required licensing and permits, it’s likely they are substantially cutting corners on the job as well to reduce their costs.
  • What do your contractors’ reviews look like?  
  • Workforce: Does your contractor hire employees or is he using a hodge-podge collection of day laborers and sub-contractors to do the work?  

The 2 Most Common Residential Irrigation Systems

Homeowners can choose between two main types of sprinkler systems: Below-ground systems and temporary above-ground sprinklers.

  • Below-ground sprinkler systems bury the pipes and lines directly into the ground. They are more expensive to install and maintain but are highly efficient and practically invisible. 
  • Temporary above-ground sprinkler systems are comparatively less expensive to install and maintain, but the above-ground hoses and pipes can pose a safety hazard. It is also easier to damage them when doing yard work (i.e., mowing, weeding, etc.)

Sprinkler System Costs Are Based on Zones, Not Square Footage

Lawn size is the other major factor that affects sprinkler installation rates. As a general rule of thumb, you can estimate a cost of about $0.40 to $1.00 per square foot. All other things being equal, companies will charge a lower price per square foot for larger yards. 

Irrigated Area (Square Feet) Approx. Lot Size Starting Price
1 – 2393 sq ft Partial Small City Lot
(Under .15 Acre)
$4340
2393 – 3500 sq ft Small City Lot
(Under .15 Acre)
$4340 – $5150
3500 – 5000 sq ft Regular City Lot
(.15-.2 Acre)
$5150 – $5560
5000 – 7000 sq ft Medium to Large City Lot
(.2-.3 Acre)
$5560 – $6135
7000 – 12000 sq ft .3 to .4 Acre Lot $6135 – $6950
12000 – 15000 sq ft Half Acre Lot $6950 – $7410
15000 sq ft and up 3/4 Acre Lot and up $7410
(Plus 40¢ per sq ft over 15000 sq ft)
Intricate designs, unique soil and site conditions, city permits, and inspections may cost extra.

Number of Sprinkler Heads

Aside from pipes, lines, and installation, you also need to factor in the number of sprinkler heads. Sprinkler heads can vary in cost significantly from $2 to $30, but more expensive heads will usually last longer than cheaper heads. The typical single-zone irrigation system uses about four to six rotating heads of eight to twelve mister-style sprinkler heads per zone. 

Soil Quality & Orientation

Lawns that are composed of compact dirt or rocky soils are tougher to work with, so installation will cost more and take longer. Often rock saws, jackhammers, or good old-fashioned muscle is required in the rocky central Texas soil.  Additionally, it takes more work and effort to install a sprinkler system in a sloped or uneven yard.  

Locating and Permitting

If you are going to be digging to install a new sprinkler around your property, you need to be sure the utilities are located and marked before beginning the project.  Permits are required for most municipalities around the Austin Metro area and a professional contractor should handle the permitting process as part of their service and include the price in their quote. A permit to install a new sprinkler system will add between $50 and $200, depending on the scope and complexity of the project.

Sprinkler Control 101: Understanding Your Sprinkler Control Box & Best Drainage Practices

Is your sprinkler system not performing as well as you hoped? The right sprinkler control box settings and drainage practices can make a difference.

As trusted irrigation specialists in Austin and Leander, our team at American Irrigation Repair is trained to know how to keep lawns green and lush. Keep reading for a few handy sprinkler tips.

Water Only As Needed

Some people prefer to stick to a strict watering schedule. It’s more convenient, yes, but not the best long-term approach for sprinkler system longevity. 

Why not wait until you see the signs of drought stress in your grass? That might look like the following:

  • Grass blades turn bluish-gray.
  • Footprint impressions become visible after walking across the lawn.
  • Grass blades curl or wilt.
  • The soil feels dry to the touch a few inches down.

Irrigation experts will tell you it’s actually good to let your lawn dry out a bit. A short period of water stress encourages the roots to grow deeper, making the lawn more drought-resistant over time.

Inspect the Irrigation Control Box & Settings

Does your lawn seem too dry or soggy? Look at your sprinkler control box’s settings. You could have set the wrong schedule by mistake. During the wintertime, it’s common to water far too frequently.  A little goes a long way when temperatures are mild.  

The controller box settings can sometimes revert to default after a power outage or maintenance, so double-check the start times, run times, and days. If the settings seem fine, your control box might have a bigger issue. Worn wiring or faulty components can disrupt performance, so you’ll need to bring in a sprinkler system care specialist for an inspection.

Ensure Your Heads are Clean – You May Need to Flush Any Clogged Screens.  

Sprinkler systems should drain automatically after each cycle. Sometimes the nozzles can back-siphon debris into them causing the screens to plug.  Ensuring the heads are set at grade correctly will help prevent debris from entering the system.  Removing and flushing the debris from the screens may be necessary if you see clogs.  

  • Clogs and debris: Small particles, like dirt or sand, can impede the flow and create pressure and coverage issues.

Drain Your Sprinkler System During Freezing Weather

During cold weather, you will want to drain your backflow valve.  Leaving water in the system during freezing temps may cause the backflow to split or crack causing leaks.  

  • Backflow: The backflow preventer’s purpose is to prevent dirty water from entering your home drinking water supply.  Backflow is caused when your system has negative pressure or when water changes direction in the pipes. Usually, this is from an open hydrant, a nearby pump, or a damaged water main.
  • Backflow devices with the highest risk of freezing damage:  Some devices are required to be above ground.  Most commonly these are installed on homes that have septic systems. If you have a device that is above ground, ensure the backflow is insulated and wrapped well. 

The safest bet is to use unions and remove the entire valve during freezing weather. This allows you to store the device indoors where it will not freeze. When draining your system to prepare for freezing weather, our team will usually drain or remove the valve to prevent component damage. We turn off the water supply valve, open all inlet and outlet drains by moving the handles to a 45° angle, and lastly, open the drain valve and let it empty.

Assess the Sprinklers

Does one spot seem to get too much water? The best water drainage solutions are the simplest. First, look for misaligned sprinkler heads – they sometimes shift due to foot traffic, mowing, or weather.

A clogged sprinkler head won’t dispense water evenly, either. Unscrew the nozzle and rinse it under running water.

Mastering the Art of Sprinkler Head Adjustment: A Guide to Optimizing Your Irrigation System

Last Modified: 12/20/24

Having a sprinkler system is a good start, but it doesn’t always mean your lawn is being watered properly. Over time, sprinkler heads can get misaligned, and your lawn’s needs can change. With simple sprinkler head adjustments, you can make sure your irrigation system works efficiently, avoiding issues like uneven patches, underwatering, or overwatering. This guide will walk you through how to keep your lawn healthy and your system running smoothly

To adjust your sprinklers, it helps to understand when and why your irrigation system may need to be fine-tuned. When you find adjusting the system is needed, you must learn how to change the spray pattern, distance, direction, and arc. Read on to learn everything you need to know about sprinkler head adjustments.

The Importance of Sprinkler Head Adjustments

With the proper know-how, you can achieve efficient and effective irrigation, giving your lawn the right amount of water in the correct places. Failure to implement these adjustments could lead to issues like the following:

  • Uneven watering: Without the perfect spray pattern, you may see patches in your lawn where some areas of grass receive more water than others.  This can cause water to pool, appear as leaks or cause disease in your landscape.
  • Water Waste: If your spray patterns overlap, overwatering the lawn or watering the hardscapes, you will ultimately waste water, spiking your water bills unnecessarily.
  • Property damage: Over time, your sprinkler heads may move in the wrong direction from people or pets stepping on them or mower vehicle and equipment damage. Some sprinklers may accidentally begin spraying structures like your house, shed, and more, causing water damage or rot.
  • Under or overwatering: Without the right water level adjustments, you may under or overwater your lawn, which will not keep the grass healthy.

Ultimately, mastering your sprinkler head adjustment strategy can help you enjoy healthier plants and water conservation savings.

Identifying Common Adjustment Needs

Sprinklers require adjustment for numerous reasons beyond being knocked out of place. The following are a few factors that could necessitate adjusting your sprinkler heads:

  • Landscaping changes: Changing your landscaping means also updating your sprinkler patterns. For example, if you install a stone patio, you likely won’t need any water in that area. Heads may need to be re-positioned, relocated, or added to prevent watering the patio and ensure adequate coverage.
  • Vegetation growth: As plants grow in your yard over time, consider what may or may not need watering. For example, young trees will likely need more frequent watering than mature ones. Bubblers may need to be relocated further into the root zone, or heads may need to be raised.  Installation of taller heads may also be a benefit to clear higher turf or plant material.
  • Seasonal adjustment requirements: You must also change your sprinkler water schedule and seasonal adjustment percentage based on the season, temperature, and weather.
  • Water distribution irregularities: By monitoring your yard regularly, you can view water distribution irregularities, such as patches in your grass or areas with stunted growth, to make further adjustments. Adding heads or coverage areas may be needed to achieve the maximum and most efficient coverage.

Adjusting Different Sprinkler Head Types

Different types of sprinkler heads require specific adjustments to optimize water distribution efficiency while minimizing overspray. Here are some basic instructions for a few of the most popular types of sprinklers:

  • Gear-driven rotor sprinklers: Use a rotor adjustment tool to increase or decrease the arc setting using the sprinkler head’s plus and minus symbols.  Many common rotors can be adjusted with a screwdriver and Allen wrench to adjust the rotor throw distance.  Many common rotor heads have a fixed stop on either the right or left top side of the head.  The plus or minus adjustment will typically adjust the arc limit on the opposite side.
  • Pop-up sprinklers with adjustable spray: Use a screwdriver or adjustment screw tool on the top of the head to adjust the throw distance.  Adjusting the arc is achieved by turning the entire head in the direction you need to adjust.  Adjustable style spray heads have a nozzle that either the top or an adjuster just below the top can rotate to adjust the arc of the head.    
  • Drip sprinklers: Adjust from the emitter to select the right flow rate for the plant material.  Many drip emitters are adjustable which can assist in areas of different plant material.
  • Impact sprinklers can be adjusted by rotating the head to adjust the stop-side arc and the metal arc limit adjustor to adjust the non-fixed side of the arc.
  • Fixed-spray sprinklers: Fixed-spray sprinklers are minimally adjustable.  They will have a distance adjuster that can be increased or decreased with a small screwdriver.  The arc is generally fixed and non-adjustable.  The right and left stops are adjusted by spinning the entire head.

Step-by-Step Adjustment Techniques

Now that you have an idea of how to adjust your sprinkler heads, let’s go through some step-by-step instructions. The exact spray pattern adjustment steps will depend on the type of sprinklers you have, so you may need to check your manual for more specific instructions.

1. Find the Adjustment Screw Thread

The first thing you should do is locate the sprinkler head adjustment screw thread, as this will allow you to make your adjustments. The screw thread is on the top or of the sprinkler or in two places on top for gear drive rotor sprinklers. You will need a screwdriver or special tool to make any adjustments to this screw adjuster.

2. Rotate the Screw or adjuster To Change the Spray Pattern

Now, you can turn your screw clockwise or counterclockwise to adjust the distance of the spray pattern. For many types of sprinklers, this action will affect the arc, ultimately increasing how far the water sprays, though it could also affect the direction of the water.

Before changing anything, be sure that the sprinkler head and water are in the right positions. Some sprinklers must be positioned a certain way before you can begin adjustments. For example, with a gear-driven rotor sprinkler, the head should be facing to the left at a completed cycle before you make any adjustments.

3. Follow the Arrows To Change the Spray Distance

Most sprinkler heads will also have arrows with plus and minus symbols indicating spray distance control. When you turn your adjustment tool accordingly, you can control how much water the sprinkler will let out. The spray distance screw thread may be in the same spot as the previous adjuster, or it may be located elsewhere on the sprinkler head, depending on which type you have.

4. Test and Change Accordingly

As you make any changes, you must turn the water on so you can test what you’ve done and adjust accordingly. After adjusting all sprinkler heads, ensure you have uniform coverage across your yard to avoid over- or underwatering.

Troubleshooting and Maintenance Tips

As you go through your sprinkler head adjustment steps, you may discover issues like clogs, leaks, or damaged components. You can clean filters to resolve clogs, though damaged components and leaks often require repairs from a professional.

Conducting routine maintenance can help you prevent issues with your irrigation system. We recommend replacing worn-out parts, cleaning filters, and checking for leaks regularly to keep your irrigation system functioning optimally.

Top 5 Sprinkler Issues Austin, TX Homeowners Face and How To Fix Them

Property owners in Leander, TX, and around Austin depend on their irrigation systems to keep their lawns green and healthy. Over time, even the best systems run into problems that can waste water and cause landscaping and property damage.

American Irrigation Repair discusses below the five leading sprinkler issues that affect irrigation systems in Austin, TX, and how to deal with them.

1. Clogged Nozzles

Dirt, sand, and debris often accumulate in sprinkler nozzles, obstructing water flow and causing uneven watering — leading to dry patches on your lawn and wasted water.

The easiest way to clean the nozzles is with either a small screwdriver or a small metal pick.  Basically, you want to knock out any debris in the nozzles to get the full pattern back.  

You may need to flush the nozzle to remove debris.  To do that, turn off the sprinkler system and unscrew the nozzle from the sprinkler head. Rinse the nozzle under running water and use a small brush or pick to remove debris. If this doesn’t get the heads to work or improve performance, you can call in an irrigation expert to inspect the system for other underlying problems.  

2. Leaking Pipes

Because they directly affect water pressure, leaks lead to low water pressure, inadequate watering, and high water bills. Of course, leaks also cause localized flooding in your yard. Leaks can develop from ordinary wear and tear, damage from tree roots, or from freezing and bursting in winter.   Sprinkler heads do have a life and after many up and down cycles seals and plastic can wear and develop marring that will cause leaks.  

An irrigation expert will identify the leak using appropriate technology and tools. After pinpointing the leak, a technician will expose the damaged area with targeted excavation, and then patch the leak or replace piping, depending on the extent of the damage.  

3. Sprinkler Head Damage

Lawnmowers, utility vehicles, foot traffic, pets, or extreme weather can all break or damage sprinkler heads. A broken or misaligned sprinkler head-in leads to uneven irrigation, water waste, and landscaping damage. With Austin, TX water rates being so high, and water restrictions being severe it’s best to fix leaks right away.  

An irrigation technician carefully removes the damaged sprinkler head from the riser and then replaces it with a new head that matches your system’s specifications. After repairs, the technician tests the entire system for proper function and adequate water pressure. 

4. Valve Malfunction

Faulty valves typically cause various zones in your irrigation system to stop working properly, leak, or have low pressure leading to uneven watering. Valves can fail because of damage from dirt, gravel, age, or debris in addition to ordinary wear and tear. Malfunctioning solenoids can also cause valves to stick open, or to fail to close.  

A valve failing to close can become an emergency in short order if the homeowner is out of town or unavailable to turn off the water.  Control valves are one of those components that you count on to work all day every day especially when the brutal Austin heat waves hit.  

American Irrigation Repair in Leander, TX, and surrounding areas irrigation can inspect all the system’s valves for issues with functionality or performance.  Rebuilding, replacing, reconnecting, or adjusting the damaged valves will often resolve the trouble. In some cases, electrical repairs, wire locating, or diagnostics are also necessary.

5. Water Pressure Problems

The low water pressure causes inadequate sprinkler coverage, while high water pressure causes misting, which also wastes water, leads to high water bills and fails to provide proper irrigation coverage.  

Technicians address pressure issues by adjusting irrigation regulators, changing nozzle flow rates, adjusting control valves, or installing pressure regulators. If these adjustments don’t solve the problem, the technician will look for blockages or leaks in the irrigation lines.

Fixing a Sprinkler Head That Won’t Rotate

Will a malfunctioning sprinkler head adversely affect your irrigation system efficiency? Absolutely. When your system fails to distribute water evenly, it leads to overwatering in some areas and heat stress in others, so you’ll want to move quickly if a sprinkler head has suddenly stopped rotating as it did before.

If you’d like some tips on how to get your sprinkler system back to peak performance, read on for some information from American Irrigation Repair sprinkler head troubleshooting.

Common Causes of a Non-Rotating Sprinkler Head

Understanding the possible causes of a malfunctioning sprinkler head is the first step in addressing it effectively. Here are the most common reasons a sprinkler might stop rotating.

Debris Buildup

Over time, dirt, sand, and general yard debris can clog and disrupt a sprinkler head’s internal mechanisms and stop it from rotating smoothly. 

One solution is regularly cleaning each of the sprinkler heads. Filters are also a preventative measure against buildup that can lead to irrigation system failure.

Water Pressure Problems 

Your sprinkler system relies on consistent and sufficient water pressure to operate correctly. When water pressure drops, sprinkler heads often do not have sufficient force to rotate. Excessive pressure also causes parts to wear out prematurely or break unexpectedly.

The main concern is thermal expansion and high water temperatures during summer. Both of these things affect the pressure inside the sprinkler system. Malfunctioning sprinkler heads can also sometimes indicate underlying water pressure issues, so don’t wait too long to schedule a professional inspection.

Obstructions Around the Sprinkler Head 

Intuitively, physical obstructions like gravel, plants, or broken ground can also impede the movement of your system’s sprinkler heads. Have small, hard objects worked their way into the moving parts? 

Excessive sprinkler head stress like this will stop the rotation and cause lasting damage. If a sprinkler head won’t move, take it as an opportunity. Being proactive about scheduling repairs early restores the sprinklers’ function before things get expensive.

Misalignment or Damaged Parts 

Normal wear and tear catches up with all mechanical devices. Has your yard’s sprinkler heads become misaligned or damaged? 

The sprinkler head components that commonly wear out include: 

  • Gears.
  • Trip collars.
  • Trip pins.

How To Repair a Sprinkler Head That Won’t Rotate

Here are some basic troubleshooting steps to address a sprinkler head malfunction.

Clean Out the Sprinkler Head 

A sprinkler professional will begin by unscrewing the sprinkler head and rinsing it thoroughly under clean water. A small brush or pin removes debris from the nozzle and filter. After the thorough cleaning and reassembly, it’s also important to test that the sprinkler now rotates.

Adjust the Water Pressure 

The second check will be using a pressure gauge to measure the water pressure in your irrigation system – the ideal result is slightly higher than inside your home, at between 50 and 60 PSI. Low pressure could indicate leaks or problems with cut-off valves or backflow valves, whereas pressure that is too high might need a water pressure regulator repair.

Remove All Obstructions 

Is the area around the sprinkler head free of obstacles like pebbles, rocks, plants, or debris? Any of these items could block the sprinkler head’s movement. 

The sprinkler head should also be a level surface or platform to provide proper alignment.

Inspect for Damage or Misalignment 

Experts will then carefully inspect the sprinkler head for any signs of wear, misalignment, or breakage, paying particularly close attention to the gears, trip collars, and trip pins. If they detect any damaged or misaligned parts, sprinkler repair teams generally adjust or replace these as necessary. The sprinkler head must also correctly align to promote proper rotation. 

A non-rotating sprinkler head might come right with a few tweaks, but getting professional help on this ensures you don’t miss anything important. You might save a lot of money and aggravation on catching complex issues early.

Why Do My Sprinklers Have Low Water Pressure?

If you’ve noticed that your sprinklers have low water pressure, you may have shrugged it off as an anomaly. Many homeowners in Georgetown, Round Rock, Austin, and the surrounding areas are surprised to learn that this is a common experience. They’re even more surprised to learn that the solutions to this frustrating problem are often simple.

Persistently low water pressure in your property’s sprinkler system leads to insufficient coverage, leaving some areas completely dry and others waterlogged. A common cause of low pressure in irrigation is a system leak, which can also lead to substantial property damage if not addressed quickly. You won’t want to wait long to sort out your sprinklers.

Read on tips and tricks from the Georgetown sprinkler repair experts at American Irrigation Repair.

Common Causes of Low Water Pressure in Sprinklers

Several reasons could explain why your property’s sprinklers are struggling with low water pressure. Here are the most common issues our sprinkler repair crew encounters in the field.

Backflow Preventer Valve or Pressure Regulator Issues

Do your sprinklers have low water pressure, yet the pressure inside your home appears normal? There could be an issue with the valves in your system’s backflow preventer device. 

Backflow Valves

The backflow preventer stops water from flowing backward and out of your sprinkler into the water supply. It usually has two pipes: one horizontal and one vertical, each with a valve. These valves must be completely open to allow sufficient water flow into your sprinkler system.

The experts will check if the valves are fully open – the handles should be parallel to the pipes. This simple fix can often restore the proper water flow to your sprinkler system. 

Pressure Regulator

The irrigation system’s pressure regulator controls the water pressure flowing from each of the sprinkler heads to ensure consistency. When this component malfunctions, you will see fluctuating pressure – some sprinklers spray further than others. You might also hear some unusual sounds, like the squealing or sputtering associated with varying pressure levels.

You’ll want to contact a professional to adjust the valves or check the pressure regulator to ensure the sprinkler repair goes off without a hitch.

Main Water Valve or Shut-Off Valve Not Fully Open

Has anyone had a reason to close the main water supply to your property recently? When sprinklers have low water pressure, you may have an issue with partially closed main water valves and shut-off valves. While the resulting restriction in flow may not adversely affect household fixtures, like water-dependent appliances or the shower, it usually impairs sprinkler performance. 

Your sprinkler system requires a consistent water flow to operate, especially when compared to household appliances that only use water every now and then. Experts will troubleshoot a pressure problem by locating the shut-off valve that serves your sprinkler system. It must be fully open.

Leaks or Breaks in the Water Line

Are you noticing your sprinklers have low water pressure? You might want a professional to inspect your entire sprinkler system for problems beyond closed valves. One more serious scenario could be leaking water lines or burst pipes, which cause a substantial drop in water pressure downstream of the fault. 

It doesn’t take heavy equipment to damage a water line, although that is certainly a common cause of sprinkler system damage. Sometimes, something seemingly insignificant, such as installing a garden stake or a trellis, can puncture or rip a sprinkler line. To detect a leak, look around your yard for:

  • Unusual depressions.
  • Wet areas of soil or vegetation.
  • Lush growth that shouldn’t be there.
  • Water bubbling up from the ground when the sprinkler system is operating. 

If some sprinkler heads work properly while others do not, there could likely be a leak in the pipes between the heads. Wherever the problem lies, you’ll want to leave this repair work to experienced professionals to avoid doing more damage.

Obstruction of Water Lines

Sometimes, sprinklers have low water pressure due to an obstruction in the water line rather than an outright leak. For example, tree roots wrap around or pierce underground lines to restrict the normal water flow. Heavy objects depressing the soil over water lines, such as parking vehicles above them, also affect the pressure in the pipes and connections.

Obstructions can restrict water flow, which will significantly reduce the pressure in your sprinkler system. A professional repair service might replace the pipe, remove obstructions, or even reroute the damaged line and flush it to restore proper water flow.  

Clogged Nozzles or Dirty Sprinkler Heads

Clogged or dirty sprinkler heads and nozzles are another common reason for low water pressure. If the issue only affects one or two sprinkler heads, dirt or debris may block them. Of course, this stops the free flow of water, which will certainly produce a noticeable pressure drop in your irrigation system.

A professional like American Irrigation Repair will inspect and clean each of the system’s sprinkler heads and nozzles. If you spot excess grass or weeds around the base of sprinkler heads, you’ll want to clear them – obstacles like this stop sprinkler heads from popping up.

Increased Demand on Municipal Water Supply

Sometimes, sprinklers have low water pressure due to municipal water supply issues. Are your neighbors also experiencing low water pressure?

How To Tell If a Sprinkler Valve Solenoid Is Bad

Last Modified: 12/20/24

An automated sprinkler system makes lawn care simple, but things can get complicated when the system malfunctions. Whether it’s from an accidental trip, a lawn mower mishap, or some extra curiosity from a child, sprinkler valve solenoids can get damaged without you realizing it. If you’re wondering how to tell if a sprinkler valve solenoid is bad, we’re here to help.

At American Irrigation Repair, we’ve been serving Georgetown, TX, and nearby areas for nearly 30 years. In this guide, we’ll show you the signs of a faulty sprinkler valve solenoid and how to identify the problem. Need help? Give us a call, and we’ll handle the repair for you.

What Is a Sprinkler Valve Solenoid?

Sprinkler valve solenoids control water pressure. They are plastic pieces with electrical wires controlling how much water flows out based on how much electricity they receive.

The valve solenoid contains several moving parts, including a plunger that controls how much water comes out of the valve. One broken part can make the entire system stop working, so it’s helpful to identify where problems may occur.

Signs the Sprinkler Valve Solenoid Is Bad

There are a few ways to identify problems. You can call a sprinkler repair company in Georgetown, TX to find the problem for you, but testing is pretty easy if you know how to tell if a sprinkler valve solenoid is bad.

Leaking Water

One of the first signs of poor valve operation is water leaking from the sprinkler valve solenoid. Water may leak from various parts, though it usually happens from the main valve.

Water may leak while the system runs or before and after you turn it on. Small leaks may not be noticeable, but you’ll see large leaks because of puddling in the yard around the sprinkler or on the sidewalk or patio next to it. Leaks are often caused by electrical issues or broken parts not allowing the valve to shut all the way.

Reduced or Uneven Pressure

You should have steady water pressure while your sprinkler system runs. If you notice the water won’t spray out as far as it used to or it changes during the cycle, something is going on inside causing this to happen. Reduced pressure is likely due to dirt or debris trapped in the system, while uneven pressure could be electrical.

Constant Flow of Water

Water running after it’s supposed to shut off is due to a faulty plunger, whether it’s mechanical or electrical trouble. Running water will make your utility bill more expensive, so it’s important to shut off the water immediately.

You can do this at the local source of water the sprinkler system is plugged into, or you can turn off the main water source, but this will affect your entire home until the problem is solved.

How To Troubleshoot the Sprinkler Valve Solenoid

Learn how to tell if a sprinkler valve solenoid is bad so you can address problems sooner rather than later. You can troubleshoot problems yourself if you enjoy tinkering in the yard, but your sprinkler repair company will be able to do this if you don’t like the hands-on approach.

Mechanical Inspection

Before troubleshooting the mechanical parts, turn off the water and electrical supply to your sprinkler system to avoid getting hurt. Remove the valve from the solenoid. If you can’t, the plunger needs to be replaced.

If you can easily remove the valve, flush it out with water to remove any debris that may be stuck inside. Replace the valve, turn on the power and water, and see if that solves your problems.

Any mechanical issues beyond these should be repaired by a professional.

Electrical Inspection

Many sprinkler valve solenoid issues relate to electrical continuity problems. Oftentimes, the solenoid doesn’t receive enough electricity to function properly, resulting in leaks or reduced pressure.

Never troubleshoot electricity yourself. The best thing you can do at home without a professional is flip the circuit breaker switch to see if it makes a difference. If that doesn’t do anything, the rest of the electrical troubleshooting should be handled by a professional.

Repair Options

When you hire a sprinkler repair company, they should be able to replace the broken part or portion of the system. Some situations may require the entire system to be replaced, but this likely won’t happen unless there is major damage or the system is so old it can’t work correctly anymore.
