Why Choose the Watts RPZ Backflow Preventer?
The Watts RPZ goes beyond conventional double check valves (DCVs) by incorporating an additional differential relief valve within its body. This critical feature protects your potable water supply by releasing pressure and preventing contaminated water backflow when a check valve fails or debris is trapped.

Featuring two independent in-line check valves, captured springs, and replaceable check seats, the Watts RPZ ensures maximum reliability and safety for your plumbing system. It is compatible with popular brands such as Fabco, Tyco, Wilkins, and Conbraco Apollo.

Ideal For High-Risk Cross-Connections
Watts RPZ backflow preventers are the recommended choice for potentially hazardous cross-connections, including:

• Swimming pools
• Sewage treatment plants
• Industrial and commercial applications

Because water authorities deem DCVs insufficient for these scenarios, RPZ devices are required under national plumbing codes.

Important Notes

• Watts RPZs are generally more costly than DCVs due to their enhanced safety features.
• Always consult your local plumbing authority to confirm the correct backflow prevention device for your project.
• All Watts RPZ and DCV products stocked by Plumbing Online are WaterMark approved and trusted across Australia for quality and value.
