The quick connect fittings are replaceable if yours is bad. The best place I've found to get them and other accessories is from the people that made them. My son has a habit of not turning off the water completely and removing the hose, thus creating a fluid lock behind the valve. To release that, all I do is take a phillips head screwdriver and place it in the opening and hit the top of the driver with my hand to release the pressure and all is well again.
Here is the link for the company I'm talking about.
