Arizona runs on irrigation. Desert landscaping in Arizona still uses drip lines and sprinklers, and every one of those systems needs a backflow device on the potable side under rules enforced by local utilities and ADEQ.

Heat is the bigger enemy in the low desert. Sun hardens rubber check discs and the UV breaks down plastic caps, so devices fail tests sooner than they would further north. Higher elevations around Flagstaff and Prescott still freeze. Grizzly Backflow & Plumbing connects you with testers for irrigation backflow testing, backflow device rebuild kits and test report filing. Call (833) 990-5874.

Why call us for backflow testing

Arizona Owners Call Us for Backflow Testing

Arizona irrigation runs most of the year, so backflow devices on drip and sprinkler lines see more cycles than devices in cooler states. Grizzly Backflow & Plumbing connects Arizona callers with testers who know that sun-hardened check rubber is the usual failure here.

If a device fails, the tester can often rebuild it on the spot with a kit for that brand and retest it the same visit. Reports go to your water provider with the serial number copied from the body tag. Call (833) 990-5874 for irrigation backflow testing, rebuild kits and backflow prevention in Arizona.

Backflow testing FAQs

Questions about backflow testing

Common questions about backflow testing in Arizona.

Talk to a person

How often does a backflow preventer need testing in Arizona?

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.

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.

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.

How much does backflow testing cost in Arizona?

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

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.
