Watts RPZ Backflow Preventers
Watts reduced pressure principle assemblies, commonly referred to as RP or RPZ backflow preventers, provide protection against both backsiphonage and backpressure in applications where reduced pressure protection is required.
Watts double check valve assemblies, or DCVAs, use two independently acting check valves to provide backflow protection in applications where double check protection is permitted by the applicable plumbing code and authority having jurisdiction.
MasterBuilder Mercantile also carries replacement components and repair kits for servicing many Watts backflow prevention assemblies. Available parts may include check valve kits, relief valve kits, rubber parts, seals, O-rings, springs, discs and other model-specific service components.
When selecting a Watts backflow preventer, verify the required type of protection, model, connection size, flow requirements, working pressure, temperature, installation orientation and applicable approvals. RPZ, double check and other backflow prevention devices are not interchangeable for every application.
Always review the manufacturer's specifications and applicable plumbing and cross-connection-control requirements before selecting or installing a backflow prevention assembly.
