Backflow Device Rebuild Kits in Gwynn Oak, MD

Every major backflow brand sells rebuild kits. A full kit for a 3/4 inch RPZ usually includes the check discs, O-rings, the relief valve diaphragm and seat seals. Spring kits are often sold separately.

A rebuild makes sense when the body is sound but the rubber has aged. Rubber in a device that sits in direct sun or chlorinated water hardens and stops sealing. A rebuild brings the device back to near-new performance for a fraction of a replacement.

The technician shuts the device down, pulls the covers, removes each check module, cleans the seats and fits the new parts. Seats that are pitted or scored may need replacing too, and some brands sell replaceable seats.

After the rebuild the device must pass a full test before it goes back on the utility's records.

Grizzly Backflow & Plumbing connects Gwynn Oak, MD property owners with technicians who stock rebuild kits for Watts, Zurn Wilkins, Febco and Apollo devices and handle the follow-up backflow testing. Call (833) 990-5874 for backflow prevention repairs.

Talk to a person
How often does a backflow preventer need testing in Gwynn Oak, MD?
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.
Who is allowed to test my backflow device?
A tester who holds a backflow tester certification recognized by your state or your water utility. Many utilities keep an approved tester list and reject reports signed by anyone not on it.
Why is water dripping from my RPZ relief valve?
