What is a Sump Pump?

Sump pumps – AKA small submersible pumps – are designed to protect low-lying areas in homes and businesses from flooding caused by heavy rain and ice thaw. They get their name from the sumps they are installed in, pits where flood and nuisance water collects to be pumped to the nearest sewer or drainage system.

Sump pumps can be run manually or automatically – automatic small submersible pumps have level control units like a float switch that will turn the pump on and off as water levels in the sump rise and fall.

Our sump pumps are generally maintenance-free under normal operating conditions, however they should be flushed with clean water immediately after use with any liquids other than water or liquids containing heavy solids, as a dirty suction strainer can inhibit the pump’s flow rate.

We recommend that you complete an inspection of your sump pump at least once a year, more if you are pumping muddy or sandy water. Before undertaking any pump inspections, ensure the electrical supply is switched off or isolated and that the pump has been flushed with clean water, exercise caution as sharp edges will be accessible within the pump and rinse all components in clean water after dismantling.

Sump pump checklist:

  • Check that the cable entry is watertight and that the cables are not bent sharply or pinched.
  • Check the impeller, pump housing and neck ring for signs of wear, replace parts as necessary.
  • Turn the pump shaft by hand to check the condition of ball bearings – replace the ball bearings if operation is noisy or heavy.
  • Check the pump’s power consumption is as expected, if it is higher than it should be this could indicate a blockage or mechanical issue that the pump is trying to compensate for – this can lead to overheating and overload damage.
  • Check the level and condition of the pump’s oil – if it is greyish white it contains water and the shaft seal needs replacing. Replace the oil after 3000 hours of operation, use vegetable oil.
