I have a switch that chatters or rapid cycles on occasion so bad that it over heats the pump motor and it cuts off. When it does it of course I loose all water pressure like this a.m. in the middle of my shower. I have changed the switch and removed the barbed fittings and hose to check for debris and I can't find anything. It is not a typical short cycle like from a bad or no bladder tank. Do you have any suggestions?
