Backflow Preventer Replacement in Johnsonville, IL

Some devices are worth rebuilding. Some are not. Backflow preventer replacement is the right call when the bronze body has a freeze crack, when parts for the model are no longer made, or when the utility says your hazard now needs an RPZ instead of a double check.

Grizzly Backflow & Plumbing connects you with plumbers in Johnsonville, IL who match the replacement to the existing piping where they can. Many makers sell lay-length compatible models, which saves cutting and re-threading. Where they cannot match, the job includes new unions and sometimes a short section of pipe.

Older devices installed below grade often get moved above ground during replacement so the new one meets current code.

The new assembly needs an initial backflow test, and the utility gets the report along with the new serial number so its records match.

If your device keeps failing every year, replacement can cost less over time than repeated rebuilds. Call (833) 990-5874 to talk through backflow prevention options in Johnsonville, IL.

Backflow testing FAQs

Questions about backflow testing

Questions we hear most often about Backflow Preventer Replacement in Johnsonville, IL.

Talk to a person
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.
Does my lawn sprinkler system in Johnsonville, IL 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.
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.
