Commercial sump pump service. I had to remove 2 pumps from the pit and disassemble the cutting wheel and intake plate from the bottom of the pumps. Cloth rags were inside the pump assembly and the shaft to the motor. Removed and cleaned out completely. Very difficult process, removed discharge pipes, and also cleaned. Installed a new cutting wheel on the number 1 pump because it is missing. Reinstalled both pumps and tested. Filled the pit with water and watched the floats and the pump working.
