Colorado's backflow rules come through the state's cross-connection control regulation, and water suppliers in Colorado have to track each device and collect test results on schedule.

The Front Range sprinkler season is short and the freezes are hard. A PVB left charged into October can split overnight, and spring start-up often turns up a cracked bonnet. Testing has to happen after start-up, before devices are drained again. Grizzly Backflow & Plumbing connects Colorado homeowners and businesses with certified testers for irrigation backflow testing, backflow enclosure and freeze protection, and backflow valve repair. Call (833) 990-5874.

Backflow testing FAQs

Questions about backflow testing

Common questions about backflow testing in Colorado.

Talk to a person

How often does a backflow preventer need testing in Colorado?

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.

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 Colorado?

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