Backflow Valve Repair in San Antonio, TX

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 San Antonio, TX.

Talk to a person
What happens if I miss the backflow test deadline?
Utilities usually send a second notice, and after that some add a fee or schedule a service shutoff. Calling (833) 990-5874 before the deadline is the simplest way to avoid 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.
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.
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.
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.
