since installing a shower pump the toilet will not flush. The water is coming through fine powered by the pump but I can't get any suction. I don't know if there is supposed to be any suction coming from the piston or syphon box thing. I have taken the handle off and if I tug on the piston pushing it down and up several times forcefully - it will flush. Do I need to replace it?
