What is irrigation leak detection?
Irrigation leak detection finds where a lawn sprinkler or drip system is losing water: a broken head, a cracked lateral line, a valve that won't close, or a leaking backflow preventer. Technicians test each zone, check the valves and trace buried lines so only a small hole is dug.
Sprinkler systems are one of the biggest water users in Cibolo homes, and many leaks only run while a zone is on. Others, like a leaking main line or a valve that never fully closes, run 24 hours a day. Both raise your bill, and both can soften the clay soil near your foundation.
Sprinkler leaks in Cibolo yards
Most Cibolo subdivisions were built with in-ground sprinkler systems, and many of those systems are now 15 to 20 years old. Clay soil shifts lines, roots crack pipes, and mowers snap heads. Summer watering hides small leaks because the whole lawn is wet, so problems often show up on the bill first.
- Run each zone once a month and walk the yard while it runs
- Check the backflow device after every hard freeze
- Reset the controller after power outages
- Follow City of Cibolo watering days during drought stages
Signs of a sprinkler or irrigation leak
- Soggy or extra-green patches that stay wet between cycles
- Water bubbling up around a sprinkler head or valve box
- A zone that keeps running after the controller shuts off
- Weak spray or heads that don't pop up fully
- Water flowing in the street gutter after watering
- Meter moving with the house and sprinklers off
If the meter still moves with the irrigation shut off at its own valve, the leak is in the house or the water line leak detection side instead.
Where irrigation systems leak
| Part | Typical problem |
|---|---|
| Sprinkler heads | Broken by mowers, cars or foot traffic; worn seals |
| Lateral lines | Cracked pipe from roots, shifting clay or digging |
| Zone valves | Debris or a worn diaphragm keeps the valve open |
| Main line | Leak between the backflow device and the valves; runs all the time |
| Backflow preventer | Cracked body or failed seals, often after a freeze |
| Drip lines | Chewed tubing or emitters popped off |
Freezes like February 2021 cracked many backflow preventers across the San Antonio area. A slow leak at the backflow device can go unnoticed for months.
How sprinkler leak detection works
- Read the meter. The meter is checked with the house off and the irrigation on, then off, to split the system.
- Run each zone. Every zone is run to spot geysers, weak heads and wet areas.
- Check the valves. Valve boxes are opened to look for weeping valves and standing water.
- Pressure test the main. The main irrigation line is tested between the backflow device and the valves.
- Trace and listen. A locator and acoustic gear pinpoint a buried leak so only one small hole is dug.

Repair or replace the system?
Most sprinkler leaks are single-part repairs. Consider a larger upgrade if the system is 20 or more years old, has repeated line breaks, or waters the wrong areas. Drip lines in beds and a smart controller can cut outdoor use a lot.
DIY safety and watering rules
You can swap a snapped head yourself and clean a clogged nozzle. Before digging deeper than a few inches, call Texas811. Also check the City of Cibolo's current watering schedule, since drought stages limit when you can run sprinklers. For leaks inside the home, see leak detection in Cibolo, TX.
Frequently asked questions
How do I know if my sprinkler system is leaking?
Look for soggy spots that stay wet, water bubbling near heads or valve boxes, and a meter that moves when all indoor water is off but the irrigation valve is open.
Why does one sprinkler zone keep running?
Usually a zone valve isn't closing because of debris or a worn diaphragm. It can also be a stuck controller. Turning off the irrigation shutoff stops it until it is repaired.
Can a sprinkler leak damage my foundation?
A leak near the house can saturate clay soil next to the slab. In Cibolo's expansive clay, that can add to foundation movement.
Is a sprinkler leak covered by the city?
No. Irrigation lines on your property are the homeowner's responsibility. Ask City of Cibolo Utility Services whether a leak adjustment is available after repair.
How long does a sprinkler repair take?
Most head, valve and line repairs take under two hours once the leak is found.
Can I shut off just the sprinklers?
Yes. Most systems have their own shutoff valve near the backflow preventer. Closing it stops the irrigation while the house keeps water, which is useful until a leaking valve or main line is repaired.
Do I need a backflow test in Cibolo?
Backflow devices protect the drinking water supply. Check with City of Cibolo Utility Services about testing rules for your property, especially after a freeze or a repair to the device.
