Backflow prevention devices are installed to block solid, liquid, or gas contaminants from going into the clean water supply. They are an important part of any irrigation system, and there are many different types you can choose from.
An air gap is an open vertical space between devices that connects to the plumbing system; this allows protection and no moving parts. The vertically installed Atmospheric Vacuum Breaker (AVB) is a simple and inexpensive solution, but one unit is not intended to be installed as the sole preventer – such AVB device must be installed at every control valve. The Pressure Vacuum Breaker (PVB) is similar to the AVB, except it can be installed to be the sole backflow preventer, and there are more regulations to follow. The Double Check Backflow Preventer (DCVA) is extremely weather resistant, and thus very popular for underground sprinkler systems. Reduced Pressure Backflow Preventer (RPBP) is the most common device used for commercial properties, as they provide the most protection from contaminants.
