Backflow Prevention

A backflow prevention device is used to protect potable water supplies from contamination or pollution due to backflow.

At Plunna Plumbing we install, configure and prevent potable water systems connecting back into non-potable water system, stopping cross connections before it becomes a health risk.

The simplest, most reliable way to provide backflow prevention is to provide an air gap. An air gap is simply an open vertical space between any device that connects to a plumbing system (like a valve or faucet) and any place where contaminated water can collect or pool, a simple air gap has no moving parts, other than flowing water.

There are many plumbing codes specify a minimum air gap distance required for various circumstances, we know which one is right for you, call us now for that peace of mind.

 

Types of Backflow Preventers
There are multiple types of backflow preventers, the three most common being the pressure vacuum breaker (PVB), the reduced pressure zone (RPZ), and the double check assembly (DCA). These are all installed in the water system immediately after the isolation valve.
