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.

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. About a month before your test, we text you the day. Then 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.
