The new anti-siphon frost proof faucet features brass construction, including a vandal resistant vacuum breaker cap. As with our standard frost proof valve, the “Hands Off” anti-siphon valves include 3/4" type L hard copper housing and operating rod.

Arrowhead valves are designed to prevent dangerous back-siphonage and backflow into a potable water supply. For use around homes, schools, commercial buildings, apartments and any place involving movable hoses attached to threaded faucets, indoors or out.

The Arrowhead Brass anti-siphon frost proof valve, provides the same non-freezing qualities as our standard wall hydrant while assuring protection against back-siphonage. This is a two-fold anti-siphonage protection provided by a springless internal check valve, automatically closing if pressure loss occurs. This in turn activates the integral vacuum breaker, which opens and allows air to enter the valve body, thus breaking the siphonage action.

“Hands Off - Never Worry Design”
This valve has integral anti-siphon that , unlike some that require manual drainage.

When using a self-closing nozzle, always relieve pressure in the hose upon water shutoff for drainage of hydrant.
