clearance for float
3. Remove pump and clean pump & piping
4. Recheck all sizing calculation to determine proper pump size
1. If voltage is under recommended minimum, check wiring size from
the main switch on property. If OK, contact power company
2. Remove, clean and check for tightness
3. Replace worn parts or entire pump. Clean parts if required
4. Check rotation. (CCW from bottom) Return if CW
5. Recheck all sizing calculations to determine proper pump size
