RPZ Valve Testing in Columbus, OH

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.

Grizzly Backflow & Plumbing connects Columbus, OH property owners with testers who handle RPZ valve testing and backflow prevention paperwork for brands like Watts, Febco, Wilkins and Ames. Call (833) 990-5874.

Backflow testing FAQs

Questions about backflow testing

Questions we hear most often about RPZ Valve Testing in Columbus, OH.

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.
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.
How much does backflow testing cost in Columbus, OH?
Pricing depends on device type, size and the local market. Call (833) 990-5874 for current pricing on backflow testing in Columbus, OH.
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.
