Idaho's drinking water rules require water systems to run cross-connection programs, and utilities in Idaho collect test reports from approved testers each year.

Pressurized irrigation from canal water is common in parts of southern Idaho. When a home has both canal irrigation and city water, the connection between them is a serious hazard and usually needs an RPZ or an air gap. Winters are long and freezing. Grizzly Backflow & Plumbing connects Idaho owners with testers for cross-connection surveys, RPZ valve testing and freeze protection. Call (833) 990-5874.

In Idaho, homes with canal-fed pressurized irrigation and city water at the same address need special care. A connection between the two is a high hazard. Grizzly Backflow & Plumbing connects Idaho owners with testers who check for that cross-connection first.

Winters are cold, so outdoor devices get drained and tested after spring start-up. Reports are filed with your water system. Call (833) 990-5874 for cross-connection surveys, RPZ valve testing and backflow testing in Idaho.

Backflow testing FAQs

Questions about backflow testing

Common questions about backflow testing in Idaho.

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.

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.

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 Idaho?

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