    Re: Newbie question on gas recovery

    You could close service valve, remove the shrader core if you must, attach line without quick coupler and then open the valve again. Apply voltage to expansion valve or use magnet to open it so that you can recover both sides of the system through your service valve. Quick couplers are a gimmick, use the valve
