Faucet leaks through anti siphon valve - B&K Plumbing

You might have missed some constrictions. Try blowing out the zone with compressed air to make sure it's clear.

Sounds like the anti-siphon cap, unscrew and check the gasket. If it is the other side tighten the screws if sill leaks valve body could be cracked and needs to be replaced.

I would search on line, if you already havn't. Otherwise a replacement faucet is $20-$30. turn the water off inside the house, drain the line, and use two wrenches to remove the faucet, (one to hold the pipe and one to turn the faucet).

Hi, Yeah it's clogged.It may be harder than you think to find a replacement part. You may have to replace to entire fixture.

Here is a site that has an instructional manual

If it is a anti-siphon valve remove the anti-siphon cap and let it rip. Remove cap on adjacent valve and let it rip check to be sure the gieser is identical. If so let it run for a long time the leak will eventually show up. Because if it worked before and doesn't work now it has a leak. Water takes the path of least resistance. I have had them access the landscape drain before and you the leak didn't appear until it emptied at the street or followed a gopher hole a few hundred feet before surfacing. Listen carefully you will probably hear it.

If water just dribbles over the anti-siphon portion with cap removed it is still not opening flow control know may be turned down. In fact I would check to ensure this isn't the entire problem turn ir counter clockwise until it stops. This is the round know in the center of the valve.

Replace the anti-siphon valve

Anti-siphon valves prevent water from siphoning back into the water supply. Also known as vacuum breakers, anti-siphon valves are used on washing machines, faucets, toilets, sprinklers and other water sources. A leak on an anti-siphon valve can cause deterioration of the appliance's external components and damage the flooring material underneath the washing machine. Therefore, a leaking anti-siphon valve should be attended to as soon as possible.

The noise is most likely originating from the anti siphon valves in the supply lines. If you remove them, the noise will clear.
