Re: Anti-Sephon Valve Leaks
Doesn't really sound like there's a problem with it to me. The purpose of an anti-siphon valve is to prevent back pressure in the hose forcing possible contaminated water into the house system.
Basically, it's a one way diaphragm. House water is able to pass, but not return. If you had the hose on, laying in the sun, the water expands and increases pressure, resulting in a drip at the valve. Similarly, if you drive over that hose, the weight of the car will pressurize the hose and water will drip/squirt out. Turn off the house pressure and the valve releases the hose pressure which usually results in a nice cold shower for whomever is standing nearby.
If you've got a constant drip at that faucet without the hosebib being on, then the hosebib itself is leaking and either needs to be rebuilt or replaced.
