There shall be no direct connection between any potable water supply system and the pool or its piping system unless protected by a backflow prevention device in ance with Chapter 6 of the California Plumbing Code.

There shall be no direct connection between any potable water supply system and the pool or its piping system unless protected by a backflow prevention device in ance with Chapter 6 of the California Plumbing Code.

When inlet pressure is above the maximum rated working pressure of the Backflow Device, the Model -PR Pressure Reducing Control Valve should be installed upstream of the Backflow Device. This provides maximum protection of the Backflow Device.

If you have a Pressure Vacuum Breaker (PVB), there are only two tests: 1. The air inlet valve must open before the gauge drops below 1.0 psi. 2. The check valve must hold a minimum of 1.0 psi.

A Reduced Pressure Zone (RPZ) lets you know the valve is functioning properly. RPZ backflow preventers consist of two independent check valves. They work like a double-check backflow preventer, but they also have an intermediate relief valve that opens to the atmosphere if both check valves should fail.

By having a buffer greater than 3.0 PSID, this would help minimize relief valve discharge from a small pressure fluctuation in a static condition. This would mean that if our relief valve opening point is 2.1 PSID than we would have to have a first check loading of at least 5.1 PSID to pass the field test.

Slow water drainage is a common sign of backflow and signifies it's time to replace your backflow device. You can notice poor drainage in your kitchen sinks, showers, dishwashers, and other drain pipes around the house. If your drain pipes are close to overflowing, you might need an emergency backflow repair.
