The DIY lawn sprinkler installer, the landscaper or a handyman is not properly trained
or licensed to test the proper backflow preventer that will protect your home and family. Not only must they be
licensed and file the proper permits and provide the mandatory "Backflow Preventer Performance Test" forms but they
may unintentionally create a cross connection that could be potentially dangerous or even lethal.
Some of the most common backflow preventers are listed below in their order of potential
hazard levels. The lower the hazard the less likely the possibility of contamination.
- Atmospheric Vacuum Breaker (also known as)- ASV valve - This is lowest level of prevention and is required only
when the degree of potential contamination is at its lowest.
- Pressurized Vacuum Breaker (also known as) - PVB valve - This is usually required for most residential lawn
sprinkler installations in New York City, areas of Westchester County, New Jersey and Connecticut.
- Double check (also known as) - a DCV assembly - This device is required by certain water authorities in Nassau
County, Westchester County and Suffolk County
- Reduced Pressure Zone Valve (also known as) - RPZ valve - This device is the highest level of backflow
prevention available. It is extremely expensive and is usually required on commercial lawn sprinkler
installations. But in certain areas of Westchester and Connecticut it is required on specific residential lawn
sprinkler system installations.
