Why does my outdoor faucet leak when I turn it on?
Sometimes your outdoor faucet will leak because the water pressure is too much for it to handle. In such a case, you’ll have to call in a plumber to diagnose the problem. Usually, high pressure is a sign of underlying problems. If you’re not careful, the high water pressure might permanently damage your faucet.
Why do anti-siphon valves make noise?
Re: Anti-siphon valve making noise (irrigation system) A backflow preventer will often chatter at very low flow rates, since it’s designed to close if flow stops. Unless you can increase the flow on those drip zones, the noise will persist. Replacing it with the same spec valve will not stop the chatter.
What causes a sprinkler valve to stay open?
The valves may have air trapped in them. A small bubble of air becomes trapped in the tiny water ports of the valve, this stops the water from flowing through the port. Since the water flowing through the port is what holds the valve diaphragm closed, the valve stays open.
Should an anti-siphon valve be open or closed?
The anti-siphon valve must not be “on” continuously for more than 12 hours. The reason for this is that when the anti-siphon valve is on a small vent is pressed closed by the water moving through the valve. This vent must open immediately when the valve is shut off.
