What is RPZ Testing?

A Reduced Pressure Zone device also known as an RPZ is installed with your plumbing system to protect your drinking water and the city water from contaminants. 

According to the Village of Mokena, IL when the pressure drops in the Village's water distribution system it is possible to have the water in your domestic plumbing drawn back into the Village's water distribution system. Hence the importance of RPZ Testing for your home.
