Backflow Enclosure and Freeze Protection in Granite Falls, WA

One hard night below 20 degrees is enough to split the bronze body of an exposed backflow preventer. The repair after a freeze is often a full replacement.

Freeze protection comes in a few forms. Insulated bags work for mild climates and short cold spells. Rigid insulated enclosures, built to the ASSE 1060 standard, add a heat source like a self-regulating cable or a small heater for places with long winters. On irrigation, draining the device through the test cocks and opening the ball valves halfway is the standard winter routine.

Enclosures need to be sized for the device and keep the relief port of an RPZ free to drain. A box with no drain opening can flood when the relief valve dumps.

Theft is a side issue. Brass backflow devices get stolen for scrap, and a locked enclosure helps.

Grizzly Backflow & Plumbing connects Granite Falls, WA owners with installers who fit enclosures and freeze protection, then schedule backflow testing once the device is back in service. Call (833) 990-5874.

Backflow testing FAQs

Questions about backflow testing

Questions we hear most often about Backflow Enclosure and Freeze Protection in Granite Falls, WA.

Talk to a person
How often does a backflow preventer need testing in Granite Falls, WA?
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.
Why is water dripping from my RPZ relief valve?
A steady drip usually means debris is holding the first check open or the relief valve diaphragm is worn. A cleaning or a rebuild kit fixes most cases.
What is a cross-connection?
Any point where drinking water piping can come into contact with a non-potable source. Common examples are a hose in a bucket, a boiler fill line and an irrigation system.
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.
