How Does a RPZ Device Work?
The RPZ device consists of two independent check valves with a pressure monitored chamber between. The chamber is maintained at a pressure that is lower than the water supply pressure, but high enough to be useful downstream. The reduced pressure is guaranteed by a differential pressure relief valve, which automatically relieves excess pressure in the chamber by discharging to a drain. 4 test cocks are installed to allow an inspector to verify proper operation of the valve with a differential pressure meter. Two gate valves (one before and one after the RPZ) are provided to allow for testing and repair.
The experience team of technicians we have here at MAS Plumbing extends far beyond the professional installation of essential RPZ valves. In fact our team can provide all the required testing and certification of RPZ valves for both residential and commercial use. During the RPZ certification process for your Glenview Illinois property, one of our licensed plumbers will create an inspection reports to be submitted to the Glenview area water authority.
