Backflow Testing, Repair and Installation

Backflow Preventers

Many fresh water systems around the world have become stressed, prevention measures have been taken to protect our drinking/potable water. In 1974, the Safe Drinking Water Act (SDWA) came into existence.

Backflow Preventers have been used to stop contamination during a drop of pressure and allowing back-siphonage into the main water lines. Backflow devices use valves to keep the water flowing in one direction. New Jersey and some water suppliers, require backflow devices in commercial or some private residences where a hazard exists.

Reduced Pressure Zone(RPZ)

Used in applications where there is a cross connection that can pose a potential health hazard

Two Independent check valves with an intermediate relief Valve if the check valves fail.

High Hazard

Double Check Valve Assembly(DCA)

Designed for non-health hazard cross-connections and continuous pressure applications subject to back pressure or backsiphonage.

Pressure Vacuum Breaker(PVB)

Testable Mechanical backflow preventer that consists of an independently operating internally loaded check valve and an independently operating loaded air inlet valve.

Used in most Residential & Commercial Irrigation systems.
