f you’re dealing with dry patches, soggy spots, or a water bill that keeps creeping up, you may not need a full system overhaul but just need a clear plan. This Sprinkler Repair checklist walks you through a simple, homeowner-friendly “sprinkler audit” you can do in about 20 minutes.
You’ll learn how to spot common problems, test coverage, and identify when it’s time to schedule professional repairs. Triple Green provides sprinkler installation, maintenance, and Sprinkler Repair services in the Houston area, helping homeowners keep irrigation systems efficient and reliable.
What You Need Before You Start
You don’t need special tools. Gather a few basics so you can move quickly from zone to zone.
Grab these items:
- A notepad or phone notes app
- A pen/marker
- A small flathead screwdriver (for many spray head adjustments)
- 6–10 identical cups (tuna cans or small plastic cups work)
- A towel (for wet valve boxes or quick cleanups)
Do your audit when you have daylight and can safely walk the yard.
Step 1 — Run Each Zone and Watch the First 60 Seconds
Start at your controller and run each zone manually. The first minute reveals the biggest issues: broken heads, geysers, and valves that don’t open correctly.
What to look for immediately
- Geyser spray (usually a broken riser, cracked head, or missing nozzle)
- Heads that don’t pop up (clogged filter screen, low pressure, or damaged head)
- Heads that won’t shut off (valve issue or debris in the valve)
- Water bubbling up near a head (possible cracked lateral line)
If you see a geyser, that’s an automatic Sprinkler Repair call. Running the zone longer will waste water and can erode soil.
Step 2 — Check for Coverage Gaps and Overspray
Once the zone stabilizes, walk the area and look for uneven coverage. Most “dry spots” are caused by misaligned heads or incorrect nozzle patterns, not lack of watering time.
Common coverage problems
- A head is tilted so it sprays above the lawn or into the street
- A shrub has grown into the spray pattern
- A nozzle is clogged so the arc looks uneven or weak
- Mismatched head types in the same zone (sprays and rotors together)
Quick fixes you can often do:
- Straighten a tilted head gently (don’t force it if the riser feels loose)
- Trim plants blocking the spray
- Clean or replace a nozzle if the pattern is broken
If multiple heads in one zone look weak, that’s a pressure or valve issue and may require professional diagnosis.
Step 3 — Do a Simple “Catch Cup” Test for Water Distribution
This is the fastest way to learn whether your system waters evenly. It’s also a great way to avoid guessing.
How to do it
- Place 6–10 cups evenly across the zone (include edges and “dry spot” areas).
- Run the zone for 10 minutes.
- Compare water levels in the cups.
What the results mean
- Similar levels across cups: distribution is fairly even
- Some cups nearly empty: coverage gaps (misalignment, clogged nozzle, blocked head)
- Some cups much higher: overspray, broken nozzle, or wrong arc
If results are wildly uneven, it’s better to fix coverage first than to increase run time. Increasing run time often creates runoff and still leaves dry areas.
Step 4 — Identify Pressure Problems
Low or high pressure causes a surprising amount of sprinkler trouble.
Signs of low pressure
- Heads barely pop up
- Spray pattern looks short and weak
- Rotors stop turning or “stall”
- One zone affects another when running
Signs of high pressure
- Mist/fog rather than clean droplets
- Water drifting in wind
- Excessive overspray onto sidewalks
- Nozzles wearing out quickly
Pressure issues often point to a regulator, a valve problem, or a zone design mismatch. If you see consistent pressure symptoms, a professional Sprinkler Repair visit can prevent repeated head failures.
Step 5 — Inspect Valve Boxes and Listen for Leaks
Valve boxes are a major source of hidden water waste. Even a small leak can run for days without being obvious from the surface.
What to check
- Is the box full of water or muddy?
- Do you hear hissing or constant water flow when the system is off?
- Are wire connections secure and dry?
If the box is flooded, you may have a valve leak or a broken fitting. This is a common repair category for irrigation companies because it’s hard to diagnose without experience. For a full list of repairs we offer, visit our Service page.
Step 6 — Check for Drainage and Runoff Issues
Houston yards can vary from sandy soil to heavy clay. If you’re seeing runoff, your system may be watering too fast for the soil to absorb.
Signs you should adjust scheduling
- Water runs down sidewalks or driveways
- Soggy areas remain wet long after watering
- Slopes wash out mulch or soil
- Fungus or consistently mushy turf appears
Simple improvement: Use “cycle and soak” scheduling (split one long run into 2–3 shorter runs with breaks). Smart controllers can automate this and improve efficiency.
When to Stop DIY and Call a Sprinkler Pro
DIY checks are great, but some problems need professional tools and repair experience.
Call for service if you have:
- A broken line (bubbling water, sinkholes, constant saturation)
- A valve that won’t open/close correctly
- Multiple zones with pressure issues
- Electrical/controller wiring problems
- Persistent leaks in or around valve boxes
Regular maintenance can also prevent repeat issues and extend the life of your system.
