    I replaced the lift solenoid and cartridge valve as well as the O-rings on the base of the ram sleeve, the O-rings on the ram itself as well as the cup on the ram.

    I pulled out the B valve and stretched the spring under the ball check and it stopped for several hours of use, then started drifting down again.

    I am wondering about the other check valve in the pump assembly?

    Anyone else got an idea?

    When it leak's down does it also angle to the left slightly?

    No drifting to the left.

    I replaced the "B" valve and we'll see. It stopped drifting sometime in the night before i replaced the valve, but i replaced it anyway.

    Its also good to know none of the cartridge valves control the left angle option.

    One for up, one for down, one for right.

    If it seemed to "fix itself" then it might have just had a piece of dirt or debris stuck in the "A" valve (black wire).
