Irrigation backflow testing, often just called backflow testing, verifies that your sprinkler system’s backflow preventer is working correctly and stopping contaminated water from reversing into your home’s drinking water supply. Pacific Lawn Sprinklers performs certified testing using state-approved equipment, so homeowners can confirm their device is functioning and meet local compliance requirements.
This applies to any home with an in-ground sprinkler system, since most municipalities require a backflow preventer on any water line connected to irrigation, drip systems included. It’s especially relevant if you’ve never had your device tested, recently moved into a home with an existing system, or aren’t sure which type of preventer you have, our technicians can identify it during testing.
Skip your annual test, and a backflow preventer can fail quietly, with no obvious sign until it’s actually tested. Most municipalities require testing every year regardless, and missing your deadline can mean fines or a water service interruption, on top of a device that’s already not protecting your water supply. A test that takes minutes catches the problem before it becomes either one.
