Parts & Repair Kits

When a valve or backflow assembly stops working correctly, the body of the unit — the housing, the ports, the connections to the pipe — is usually still perfectly functional. What's failed is almost always a specific internal component that wears out from repeated cycling, exposure to sediment, or age. A repair kit replaces exactly that component, which is why fixing a valve with a kit typically costs a fraction of replacing the entire assembly and takes a fraction of the installation time.

Vent float kits restore proper function to the venting mechanism inside a valve or backflow assembly — a small float that regulates air and pressure release, and one of the more common points of failure since it's constantly in motion during normal operation. Diaphragm assemblies replace the internal seal that actually opens and closes to control flow through a valve; a worn or torn diaphragm is one of the most common reasons a valve won't fully shut off or won't open at all, even when everything else about the valve looks fine. Bonnet and poppet kits address the components that take the most repeated mechanical stress — the poppet is the part that physically seats to stop flow, and the bonnet is what holds the internal assembly together under pressure, both of which wear from the same cycling that eventually requires a repair.

The right kit depends entirely on matching it to the specific valve or backflow assembly model you're repairing — a kit built for one manufacturer's Electric Valves won't necessarily fit another, and the same applies across Double Check Valve Assembly (DCVA), Pressure Vacuum Breaker (PVB), and Reduced Pressure Zone Assembly (RPZ) assemblies. Checking the model number on the existing unit before ordering a kit avoids the common mistake of buying a repair kit that doesn't fit.
