What is RPZ?
RPZ (Reduced Pressure Zone) is a type of backflow prevention device that is widely used to contain premises utilizing hazardous materials from entering city water supply.
What we can do for you?
We provide installation of backflow prevention devices throughout New York City. Backflow occurs when water flows in reverse and contaminates the clean water supply. Backflow happens when there is a pressure drop in the supply line, which can cause water that has pollutants and other hazardous chemicals to flow through your water supply.
It is important to note that only certain properties and businesses are required BY LAW to have a backflow prevention device installed. Below is a list of properties taken from the NYC Department of Environmental website who require a backflow prevention device.
