Leaks & Breaks
Sprinkler system leaks and breaks occur when pipes, fittings, valves, or sprinkler heads become damaged or worn, allowing water to escape where it shouldn’t. Irrigation systems live underground, under pressure, and exposed to soil movement, freezing temperatures, and physical impacts—so over time small failures are inevitable.
How Do You Find a Leak in Your Sprinkler System?
Leaks and breaks in a sprinkler system can be found by observing signs of water loss and checking system performance. Key indicators include:
-
Wet or soggy spots in the yard when the system is off
-
Unusually high water bills.
-
Low water pressure or sprinklers not spraying properly.
-
Areas of very green or rapidly growing grass compared to the rest of the lawn
-
Visible water pooling around sprinkler heads or valves
Regular inspections and running the system zone by zone help identify where the leak or break is occurring so it can be repaired quickly.
Can Sprinklers Leak When Off?
Yes, sprinklers can leak even when the system is turned off. This usually happens when a component inside the irrigation system is not sealing properly. Water pressure remains in the pipes, and if something fails to close completely, small amounts of water can slowly escape.
Common causes include:
-
Leaking valves – The valve may not fully close, allowing water to continue flowing into a zone.
-
Low head drainage – Water left in the pipes drains out through the lowest sprinkler head after the system shuts off.
-
Worn seals or diaphragms – Internal parts inside valves wear out over time and stop sealing correctly.
-
Damaged sprinkler heads – Cracked heads can slowly leak residual water.
These leaks are often small at first but can waste water, create soggy spots, and increase water bills if not repaired.
Best Sprinkler Repair
Preventing leaks in a sprinkler system is mostly about maintenance and good system design. Irrigation systems live under pressure, buried in soil, and exposed to weather, so small preventative steps keep little problems from turning into underground fountains.
