Yes. Some irrigation leaks can waste water even when the controller is not actively running a watering schedule. Whether that happens depends on where the leak is located and whether that section of piping remains under pressure.
Leaks before the zone valves
A leak on a pressurized irrigation supply line can continue whenever the irrigation water supply is on. These leaks may create persistently wet soil or unexplained water use.
Leaks after a zone valve
Lateral piping normally carries pressure while its zone is running. However, a valve that seeps internally can allow water into a zone while the controller is off, sometimes producing drainage or a slowly leaking sprinkler head.
How the leak is isolated
The timing and location of water are important clues. Our sprinkler leak repair process determines whether the problem is supply-side, valve-related or within a particular zone before digging.
