Backflow Valve Repair in Sonora, CA

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 Sonora, CA.

Talk to a person
How often does a backflow preventer need testing in Sonora, CA?
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.
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.
What is the difference between an RPZ and a double check valve?
Both have two independent check valves. An RPZ adds a relief valve between the checks that discharges water to atmosphere if the checks leak, which is why it is required on high-hazard connections.
How long does a backflow test take?
A residential PVB or double check test usually takes 20 to 30 minutes. Large commercial and fire line assemblies take longer.
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.
