The Apollo ½ Pressure Vacuum Breakers prevent contamination of the potable water supply due to back-siphonage. An integral freeze protection relief valve serves to reduce the possibility of damage due to intermittent freezing conditions.
The modular check valve cartridge provides a captured spring, a replaceable seat and a reversal silicone seat disc. This Made in America assembly features Apollo ½ ball valves with stainless steel handles and nuts as standard and carries the five-year Apollo ½ factory warranty.
