Backflow Valve Repair in Hilo, HI

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 Hilo, HI.

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.
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.
What does a failed backflow test mean?
A check valve or the relief valve did not hold its required pressure differential. The device needs repair or replacement, then a retest before a passing report can be filed.
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 Hilo, HI?
