How to Install a Submersible Pond Pump

A submersible pond pump is used in ponds and fountains to move water, either over a waterfall or through a fountain.

Different from a sump pump, they are made to run 24 hours daily, 7 days a week, thus enabling you to enjoy your pond at any hour. Pumps are rated in gallons per hour (GPH) pumped, and are available in models ranging from 70 GPH for a tiny indoor fountain to 6000 GPH for a huge outdoor waterfall. These pumps provide oxygen for fish, and often pull water through a filter and up and over a waterfall, making wonderful water sounds that relax us and add drama to the garden.

Place your pump up off the bottom of the pond. If the pump sucks in pond debris, it can make it run slower and eventually shorten the pump's life. Place the pump on a cinder block or stack of rocks to keep it off the pond bottom.

Attach a piece of flexible tubing to the output of the pump.

Things You Will Need

  • Submersible pump
  • Ground fault circuit interrupter (GFCI) electrical outlet
  • Flexible tubing to fit on the outflow of the pump
  • Hose clamp, appropriately sized.
  • Screwdriver

Tip

  • Clean your pond pump to ensure long pump life.

Warning

  • Always use a GFCI electrical outlet. It will cut off electricity instantly if water touches the outlet.
