Oklahoma utilities in Oklahoma track backflow devices under the state's public water supply rules, with yearly notices to commercial and irrigation customers.

Weather here swings from triple-digit summers to ice storms. Ice and hard freezes crack exposed PVBs, and hail can bend bonnets. Oilfield and ag sites have chemical connections that call for RPZs. Grizzly Backflow & Plumbing connects Oklahoma property owners with testers for PVB testing, RPZ valve testing and backflow preventer replacement. Call (833) 990-5874.

Backflow testing FAQs

Questions about backflow testing

Common questions about backflow testing in Oklahoma.

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.

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.

How much does backflow testing cost in Oklahoma?

Pricing depends on device type, size and the local market. Call (833) 990-5874 for current pricing on backflow testing in Oklahoma.

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.
