Water hoses have a female fitting on one end that can become stuck. The most likely location for the fitting to become stuck is onto a faucet. Many hoses are attached to a faucet the entire summer. They can become stuck and may not be easy to remove in the fall. Removing a stuck water hose fitting is accomplished with only a couple of items in less than 30 minutes.
Turn off the water to the faucet using the faucet handle. Discharge the water in the hose by squeezing the sprayer at the other end, if there is a sprayer attached. If there is no sprayer attached, the hose will not need discharging.
Spray the fitting with a penetrating catalyst. Ensure that the catalyst soaks the connection between the fitting and the faucet. Let the catalyst set for 20 minutes to loosen the fitting.
Grasp the hose fitting with a pair of slip-joint pliers and hold it securely. Turn the fitting counterclockwise to loosen it. Keep turning the fitting until it can be removed by hand.
Repeat the process if the fitting refuses to detach from the faucet. Eventually the fitting will unscrew.
