        Comments about 3 Way Powerhead Conversion Kit (Water):

        I have a 3 zone base board heater. My hard water causes the valves to seize and render them useless. I took them apart, got them moving again but the fix was literally days. Buy a new valve and if its been seized for some time the motor probably needs replaced at the same time.

        Comments about 3 Way Powerhead Conversion Kit (Water):

        Cheaper and less effort than replacing valves. However, the rubber swells and If the ball were redesigned in a different material, we may not need to go through this process. Buy a stack of them cause you are going to need to replace all of them.
