Call toll free at 877-337-BAIR we have RPZ Valves In Stock

RPZ stands for Reverse Pressure Zone.  These devices are used to prevent back flow or back siphon of contaminants into our public water supply.  The state mandates that RPZ’s be installed where there is fire protection and or lawn watering systems. It is used in commercial & residential buildings. The reason for RPZ’s is that there is a chance that water in the building could get sucked back into the village water supply if the village water pressure drops and it sometimes does for one reason or another.  There have been instances where chemicals from a facility have been found in city water supplies (cross contamination) due to back flow. State regulations require that these devices are to be installed by a licensed plumber, who is also certified by the EPA as an installer and tester of these devices. Always ask for proof of license and RPZ certification when having an RPZ installed or certified. The village mandates that paperwork be attached to the valve itself and also a copy is to be sent to the Public Works Department upon recertification each year.

We have many licensed plumbers on staff and 5 of them are certified installers and testers of the RPZ.
