Automatic Lawn Sprinklers - Maintenance - Repairs - Installations

A backflow prevention valve on a lawn sprinkler or drip irrigation system can come in many types and brands. Each device offers an additional level of protection against the possible chance of the irrigation water from backing up into your domestic drinking water. Many city and town water departments and water authorities mandate that specific backflow preventers are installed on every water service/ supply line to an underground irrigation system. This is also true for a drip irrigation system, garden irrigation system or any water service line that could have a potential chance of contamination with irrigation water.

Pacific Lawn Sprinklers' licensed and certified installers and testers are trained in the proper application and specific installation procedures required to install any required cross connection device.

The DIY lawn sprinkler installer, the landscaper or a handyman is not properly trained or licensed to install or 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 unintentional 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.

1. 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.
2. 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.
3. Double check (also known as) - a DCV assembly - This device is required by certain water authorities in Nassau County, Westchester County and Suffolk County
4. Reduced Pressure Zone Valve (also know 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.
