Backflow protection has become an ever increasing concern as the protection of safe, clean drinking water increases in awareness. To help keep our public water clean it must be isolated from undesirable reversal of water flow or mixtures of water with liquids, gases or toxic health hazard substances into the distribution of the potable water system. Backflow Prevention assemblies provide that protection.

The State of New Jersey requires all commercial properties to certify backflow prevention assemblies once every year. This includes backflow assemblies on Fire Service Lines, Domestic Water and Lawn Sprinkler Systems.

NJSTI has certified backflow assembly technicians that install, test and certify all types of backflows, including; Dual Check, Reduced Pressure Zone and Anti-Syphon.

If you are being required to install a new Backflow Assembly on an existing Fire Sprinkler System, NJSTI can perform the required Hydraulic Calculations to prove system water requirements are met.
