Backflow Valve Repair in Baltimore, MD

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 Baltimore, MD.

Talk to a person
Can a backflow preventer freeze?
Yes. Trapped water expands and can crack the bronze body or blow out the bonnet. Insulated enclosures, heat cable or draining the device for winter prevent it.
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.
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.
How much does backflow testing cost in Baltimore, MD?
Pricing depends on device type, size and the local market. Call (833) 990-5874 for current pricing on backflow testing in Baltimore, MD.
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.
