Backflow Enclosure and Freeze Protection in Larsen, WI

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 Larsen, WI 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 Larsen, WI.

Talk to a person
How often does a backflow preventer need testing in Larsen, WI?
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.
Does my lawn sprinkler system in Larsen, WI need a backflow preventer?
Almost every US plumbing code requires one on irrigation, since fertilizer, pesticide and standing water at the heads can siphon back. The device type depends on local code and how the system is laid out.
Can a backflow preventer freeze?
Yes. Trapped water expands and can crack the bronze body or blow out the bonnet. Insulated enclosures, heat cable or draining the device for winter prevent it.
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.
