Rain Bird APAS were used commonly in the years leading up to 2008. They were among the most commonly bought and installed valves in the United States. Production of the APAS-100 was discontinued in 2008 and no replacement part was ever created. Sprinkler Warehouse has scoured the country to source any remaining new product that is still available. The product being offered here is NEW and unused.
Automatic Anti-Siphon Sprinkler Valve for Backflow Prevention. The APAS models meet or exceed most building code requirements for connecting a sprinkler system to a city water supply. These valves prevent the possibility of back-siphoning of water from sprinkler lines into the drinking water. The anti-siphon valves must be installed at least 6 inches above the highest sprinkler in the circuit to work properly.
Do not use this anti-siphon valve as a main line backflow device, nor as a master valve. It is not designed nor approved to be under constant water pressure on both sides of the valve. Do not install any other valves downstream. If installed incorrectly under constant pressure on both sides of the valves, it is possible that the valve will fail or burst.
