5 things to try before Replacing a Faulty Pond Pump

Occasionally you may experience problems with your pond pump. Before you go out and purchase a new one, try our top tips to see if it fixes the issue.

  • Check the water flow to the pump. One of the most common pump issues is caused by water flow. A pump can’t push water if it doesn’t have access to it. Check to see if there is anything keeping water from getting to the pump such as debris.
  • Flush your plumbing – disconnect the fitting above the check valve, allowing water to flow out of the system and back into the skimmer box, carrying any possible blockages with it.
  • Inspect them pump. Check the intake for any debris. Most pumps will deal with small debris pretty well, but larger items such as stones could get block the impeller or intake. Clean out the intake to make sure that it’s clear.
  • Make sure the pump isn’t vapor locked. This occurs when the pump gets an air bubble trapped in the main internal space of the pump (volute). The impeller will spin, but it won’t be able to move water because of the air bubble. If this is the cause, tilt the pump underwater so that the intake is upward, letting the air bubble escape.
  • Check the power supply. If the impeller is able to move freely but still isn’t spinning when plugged in, take it to a different electrical outlet with a ground fault to test. If the pump works at another outlet, then something is wrong with the electrical supply at your pond, not the pump.

If none of the above work, contact the manufacturer of the pump if it’s still under warranty or alternatively contact a pond specialist who may be able to assist.
