electrical code (Nec) and with any local codes and ordinances. employ a licensed
electrician. check voltage at motor terminals and at meter when pump is operating. If
low, refer to wiring instructions or check with your power company. check loose con-
nections.
A pump designed for higher head needed.
locate pump closer to source of water. Make sure suction piping is large enough.
check suction piping.
remove and clean.
use larger strainer or clean.
Add lengths of suction pipe to keep submerged end well below the water surface.
If caused by suction pipe friction, enlarge piping.
A pump designed for higher head is needed.
order replacement parts using repair parts list.
check suction piping.
Move pump nearer water level.
check water supply. Add length of pipe to suction to keep submerged end under water.
take motor to authorized motor repair shop.
