The inspection and testing of all backflow devices is required to ensure water flows away from a building rather than towards a building. Backflow testing includes inspection of Double checks, Pressure Vacuum Breakers, Rain/Freeze Sensors and all fire line backflows.

Back flow preventors are those devices specifically designed to prevent the harmful effects of backflow and back-siphonage. To understand better how a back flow preventor works, one must first understand the nature of back flow. Back flow generally occurs when there is a sudden drop in water pressure from the main water supply to a

What is a back flow valve? To understand what it is, we first must look at its purpose. In 1972, Congress passed what is generally known as the Clean Water Act; it was actually entitled the Federal Water Pollution Control Act.  Subsequent additions to that act were passed in 1977 and 1987. The main thrust

What is a back flow preventor? It is exactly what its name implies, a device which prevents back flow.  Seems fairly straightforward, doesn’t it, unless you don’t know what backflow is, in which case it sounds like Ancient Greek. So let’s start with backflow.  Backflow occurs when the water in your pipes reverses direction and
