    My Taco pump within a split Climatemaster unit is not working and I have tried to just change the cartridge with no luck. My question is if the unit is piped as instructed, is it necessary to drain the buffer tank, or can I just valve it off closest to the pump itself? I drained it down last time, but after looking closer I am not sure that is required. Thanks for any response.

    The board is good is good and when I checked ohms on the motor, it is bad.

    If you have shut-offs on both sides of the pump, they are for pump change outs. Draining the tank isn't necessary, since you already did it recently.

    Is it an ECM or does it have a capacitor? I would check the capacitor before buying a new one.
