Do I need a vacuum breaker (backflow preventer) for my sprinkler system by code?
Saturday, November 13, 2021
A vacuum breaker is only required for a sprinkler system that uses the same water source that provides potable water for the residence. So a sprinkler system served by a separate well, or by a recycled water system, does not require a vacuum breaker—because the possibility of cross-contamination of the drinking water after a water pressure failure is eliminated. See our articles What is a "cross connection" in a home's plumbing system? and Why is a backflow preventer required on lawn sprinkler systems? to learn more.
