Backflow Preventer definition: A device that allows water to go through it in one direction, but prevents it from going backwards in the opposite direction.

A backflow preventer is like a one-way gate for water. Most backflow preventers are used to keep unsafe water from reversing flow and entering the clean water supply. Sprinkler systems pose a significant threat to the drinking water system. By nature, sprinkler heads may reside in a pool of yard/animal waste, pesticides and fertilizers.

Backflow Testing "Ohio Certified" 

1, Pressure Vacuum Breaker (PVB) – ASSE 1020; this assembly must be able to be located outside, one (1) foot above the highest sprinkler head, and no more than five (5) feet above grade at the installed location.                                                                                                           

2, When the parameters for a PVB cannot be met, a Reduced Pressure-Principle (RP) - ASSE 1013 shall be installed. Required to be outside, no restriction on elevation of sprinkler heads, and mounted 18”- 60” above grade at the installed location. Both assemblies require their annual test at the time of spring seasonal start-up.
