I don't use a quick connect or auto shut off. When I disconnect the hose I flush the hose and the valve with water from a bottle while I'm still wearing the lower part of the suit. This way it's clean and you can leave the hose open so it can dry out.4. When you use a quick connect with auto shut-off for the p-valve, do you remove the provided on/off valve, or do you use that in addition to the quick connect?
