Backflow testing FAQs

Questions about backflow testing

Questions Mercer Island, WA property owners ask about backflow testing and backflow prevention.

Talk to a person
How often does a backflow preventer need testing in Mercer Island, WA?
Most water utilities require a test once a year. Many also require one at installation, after any repair and after the device is moved. Your utility's notice letter gives the exact due date.
Do I need an expansion tank after installing a backflow preventer?
Often, yes. The device makes your plumbing a closed system, so heated water cannot expand back to the main and the water heater relief valve may start dripping.
What is a cross-connection?
Any point where drinking water piping can come into contact with a non-potable source. Common examples are a hose in a bucket, a boiler fill line and an irrigation system.
How much does backflow testing cost in Mercer Island, WA?
Pricing depends on device type, size and the local market. Call (833) 990-5874 for current pricing on backflow testing in Mercer Island, WA.
Can a backflow preventer be repaired instead of replaced?
Often it can. Rebuild kits with new discs, springs and seals are sold for most brands. Replacement makes more sense when the body is cracked or parts are no longer made.
