Most Liberty Lake homes have a backflow prevention assembly on the irrigation system, typically a pressure vacuum breaker (PVB) mounted near the sprinkler shutoff. Washington requires these assemblies to be tested every year by a certified tester (WAC 246-290-490), and your water provider tracks who has and hasn’t filed a passing report.
Who sends the test notice in Liberty Lake?
Most Liberty Lake homes get their annual cross-connection control notice from the Liberty Lake Sewer & Water District. The notice lists a deadline; miss it and the district can follow up with shutoff warnings until a passing test is on file. We test your assembly on site and help get the report where it needs to go so you’re marked compliant.
- Liberty Lake Sewer & Water District
Irrigation is everywhere in Liberty Lake — HOA lawns, golf-course-adjacent lots, and newer builds along the River District all mean sprinkler systems with testable assemblies. If you just bought a home here, check near your irrigation shutoff for a PVB; that’s usually the device on your notice.

We notify your district
Once you’re booked, we tell your water district a test is scheduled — that’s the main thing that keeps a shutoff from happening. Then we test, certificate, and help file the pass.

FAQ
Backflow testing questions in Liberty Lake
Straight answers for Liberty Lake homeowners on price, deadlines, and paperwork.
A standard single-device residential backflow test in Liberty Lake is $60 if you book by Feb 28, 2027 (regular $75). Homes with more than one assembly (for example irrigation plus a fire line) are quoted up front before we book. You pay when you book.
The Liberty Lake Sewer & Water District requires annual testing of backflow prevention assemblies under Washington’s drinking water rules (WAC 246-290-490). The district sends yearly notices and tracks passing reports from certified testers.
Liberty Lake is our home base. You don’t pick a day: once you book, you’re on our schedule, and we plan each day’s route to reach as many homes as we can. We text you the day before and again about an hour before we arrive. You don’t need to be home — the test takes about 20 minutes. We also notify your water district that a test is scheduled.
On most Liberty Lake homes it’s a pressure vacuum breaker (PVB) on the irrigation line — look for a bell-shaped brass device about a foot above ground near your sprinkler shutoff, often on the side of the house or in a landscape bed.
