In 2024, homeowners across the country spent $250 on average to repair a residential sprinkler system, with the majority of them paying between $130 and $360, depending on how serious the problem is. While these costs didn’t break the bank, Denver and Colorado homeowners increasingly value even small savings when it comes to their access to water, and that adds up quickly when multiple problems go unaddressed.
Many irrigation system repair needs can be completely avoided. Small issues can arise quietly, such as a small leak, a clogged nozzle, or a sprinkler head that is not performing as it should. This slowly cascades into bigger issues, which means frequent service calls and costly repairs.
The earlier you can catch irrigation system problems, the better for your wallet. In this article, we have highlighted the most common signs that suggest you may need to get your lawn's irrigation system repaired by an expert landscape management company in Denver to catch the problems earlier, before they become an expensive repair.
Common Repair Signs Not To Ignore
Typical repairs, like irrigation head replacement, cost around $250 for a 2-cent piece of plastic or rubber. Doing simple maintenance probably saves 20% of that cost right away.
1. Uneven Water Coverage
Probably the most obvious issue you may see is patchy watering; some areas of the lawn are lush and growing, while others are brown and dry. The inconsistency or pattern may be due to clogs in heads, broken nozzles, or shifted sprinkler heads.
What does it look like: Brown or white patches next to green turf, or "bog spots" in other areas.
Why does it matter: Hydro-stressed grass from uneven moisture, rooting disruptions, and opportunistic weed growth.
How to fix it:
Check the sprinkler heads for debris buildup or shifting. Clean or replace malfunctioning hardware, align spray patterns, and check pressure settings. If the issue isn't resolved, it may be a deeper problem with buried leaks or broken lines.
2. Strong Leaks and Saturated Areas
Are you finding puddles on your lawn even though it hasn't rained? That's a good sign that something’s wrong.
Signs: Bubbling water at heads, water near vents, constantly wet soil in multiple patches of the lawn, or areas that never dry out during normal watering and growth.
Importance: Leaks waste water, raise utility bills, and promote poor conditions for healthy root systems.
Fix list:
Familiarize yourself with your system's valve box, then watch your system run through a complete cycle. Systematically shut down the system and mark the pooling water (puddles). Simple leaks can be fixed by replacing heads or fittings; more serious leaks require a professional lawn care expert in Denver.
3. Erratic or Low Pressure
Do some heads have a weaker spray? Or do some zones spray too strongly? Both are indicators of pressure problems.
Signs to notice: Heads that droop, misting nozzle sprays, or sprinklers shooting far off-range.
Importance: Too low or too high pressure leads to inefficient watering patterns with both overly dry and overly wet areas, risking plant health and resilience issues for the system.
How to diagnose: Look for clogged filters or broken pipes. If adjusting the regulator or system nozzles does not help, then return to the issue of gradients in pressure between zones. In this case, there is a possibility of either a broken valve or a clogged line, which ultimately requires professional servicing.
4. Control Valve or Zone Issues
Your irrigation controller is the brain of your system. If it is not working properly, an entire zone could be shut down.
How to identify: A zone that simply does not turn on or a zone that stays on regardless of timer settings.
Why immediate attention is needed: A failing zone may result in thirsty grass or a flooded lawn, which may lead to rot or pest issues.
Quick fixes:
Reset the controller, replace stuck valves, or lubricate them. For electrical failures or wiring issues, have a professional irrigation system repair expert in Denver troubleshoot your system.
5. Unexplainable High Water Bills
Noticed your water usage has spiked with no explanation? It could be caused by hidden leaks or inefficient watering settings.
What to watch: Unexplainably higher monthly bills, especially in early-season months when it doesn’t line up with anticipated watering increases.
Consequences: Besides costs, wasted water is taxing on Denver’s supply system, which has been reported as a major issue in the last couple of years during peak irrigation.
Action steps:
Compare your usage to previous years. If all conditions were held constant, you should investigate the irrigation system. You can document meter readings before and after your irrigation cycle to either confirm or rule out a leak.
6. Electrical Failures and Weird Sounds
Are you experiencing hissing, whining, or buzzing noises when the system runs? That should not be happening.
Signs: You may hear hissing around the pipes or heads, unusual noises in the controller, or humming from a valve.
Implications: Causes of noise could be high pressure, leaks, air in the system, faulty valves, or short-circuiting, which generally indicate that some repairs are needed.
Fixes: Replace malfunctioning parts, and for electrical issues, contact a licensed electrician to keep everything safe and in compliance.
7. Soil Erosion and Runoff
Is your lawn moving or eroding in places?
Watch for: Torn-up grass and rain flowers.
Issues: It's more than damaging turf; it's causing problems with root structure and soil stabilization.
Fixes: Reduce spray time and adjust angles. If the pressure is too high, use mist-resistant spray heads. If your turf is still eroding, add mulch or grade the soil away from the building.
Preventative Maintenance: Key to Longevity
Preventive maintenance is key and will significantly reduce repair costs with periodic inspections.
What to include in a Seasonal Tune-Up:
Clean and adjust nozzles and sprinkler heads.
Inspect each zone for water coverage.
Check and lubricate valves.
Inspect, calibrate, or reset mechanical controllers for spring and fall operations.
Ensure proper pressure, drainage, and rooting.
