More Info

The 3/4" 420XL Pressure Vacuum Breaker Assembly is used for high health hazard, residential irrigation and potable water applications for protection against backsiphonage of contaminated water into the potable water supply. The 420XL is equipped with an internal, integral anti-freeze relief valve to reduce the risk of costly valve damage in intermittent, non-seasonal freezing conditions. It is best used under continuous pressure, and features a modular design to reduce repair time and costs. Its low-lead cast bronze main valve body and 300 series stainless steel springs effectively resist corrosion.
