RPZ Valve Testing in Pittsburgh, PA

An RPZ, or reduced pressure zone assembly, protects the public water main from high-hazard connections: boiler feeds, chemical injection, car washes, medical and dental offices, and irrigation with fertilizer injection.

The test has three parts. First the tester checks that the relief valve opens at 2.0 psid or more. Then the first check is read, and it usually holds a differential of 5 psid or higher. Last, the second check is tested for tightness against backpressure.

A dripping relief port is the classic RPZ complaint. Most of the time a pebble or scale from a recent main break is holding the first check open. Sometimes the relief diaphragm itself has torn.

RPZ assemblies must sit above grade with open air under the relief port. One buried in a pit can flood and siphon dirty water back, which is why most codes forbid it.

Backflow testing FAQs

Questions about backflow testing

Questions we hear most often about RPZ Valve Testing in Pittsburgh, PA.

Talk to a person
How often does a backflow preventer need testing in Pittsburgh, PA?
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.
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.
Will my water be off during the test?
Yes, briefly. The tester closes the shutoff valves on the assembly while reading the checks, so water downstream of the device is off until the test is done.
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.
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.
