If you?re tired of worrying about high lead levels, harsh water conditions and backflow preventer theft, then solve all of these problems easily with the 1 1/2 inch DC-501 from A.R.I. The 1½ ? double check backflow preventer is recommended where the degree of contamination doesn?t require the use of a reduce pressure device.
The DC-501 is an innovative solution, made of two independent, spring-loaded check valves. It also utilizes four test cocks and two resilient seated shut-off valves which finish the device. This dependable and simply serviced backflow doesn?t require specialized tools to service as its two, easily replaceable, spring check valves sit inside independent capsules. This nylon composite body and modular design, make it the next generation of backflow preventer.
Each check valve is engineered to hold a minimum of 1 PSI throughout the backflow preventer during normal operation. If the pressure leaving the mechanism ever rises above the incoming pressure, both check valves will close off to keep any backflow from happening. It has a working pressure of 150 psi and can withstand temperatures up to 110 degrees. Our double check backflow prevention device is meant to provide exceptional protection against undesired back flow.
