Backflow Valve Repair in Seattle, WA

A failed test is not the end of the device. Most backflow valve repair comes down to rubber and springs.

The common fixes look like this. A check that will not hold 1.0 psid gets a new disc and a cleaned seat. A relief valve that spits on an RPZ gets a new diaphragm or a cleared first check. A test cock that weeps gets replaced, since they are threaded in and cheap. A cracked bonnet on a PVB gets swapped for a new one from the same maker.

Debris causes more repairs than wear. After a main break or hydrant flushing, sand and scale can lodge under a check and fail an assembly that tested fine the year before.

Once repaired, the assembly has to be retested, and the repair is noted on the report that goes to your utility.

Backflow testing FAQs

Questions about backflow testing

Questions we hear most often about Backflow Valve Repair in Seattle, WA.

Talk to a person
Who is allowed to test my backflow device?
A tester who holds a backflow tester certification recognized by your state or your water utility. Many utilities keep an approved tester list and reject reports signed by anyone not on it.
Does my lawn sprinkler system in Seattle, WA need a backflow preventer?
Almost every US plumbing code requires one on irrigation, since fertilizer, pesticide and standing water at the heads can siphon back. The device type depends on local code and how the system is laid out.
Who sends the test report to the water utility?
The tester usually files it, either on the utility's paper form or through its online portal. Ask for a copy for your own records.
Is fire sprinkler backflow testing different?
Yes. Along with the standard check valve test, NFPA 25 calls for an annual forward flow test on fire line backflow assemblies. Results often go to both the water utility and the fire authority.
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.
