I have an outdoor faucet connected to a garden hose and pistol type spray nozzle. The connection is leak free until I turn the water off and pull the trigger on the spray nozzle to get some of the rest of the water out and relieve the pressure on the hose. When I do this, water comes gushing out of the connection from the faucet to the hose.
Does anybody have any idea what this is and what I can do about it?
Some other information:
-I thought it could be the the washer, but I just bought a new hose and made sure the rubber washer was in good share and in place
-I've tried both wrench tightening the hose as well as the other end of the spectrum with light hand tightening
-The faucet itself is only about 3 years old, and as I mentioned, doesn't leak while the water is on
Adding photos of the faucet: one with the hose attached and one without
