Troubleshooting Pump Problems


We have been getting a lot of questions about reviving dead pumps as many of you in the North are trying to start up your ponds for the spring.

In this Aquascape Video, Dave Kelly  – The Tech Guy –  brings up some great tips on steps to go through to bring your pump back to life.

The major things to check are:

  1. Make sure water level is high enough to get to pump (Duhhh – but sometimes easy to miss) (Hint – Use AutoFill systemto keep water level constant)
  2. Check and Clear Skimmer Debris net or basket – If this is clogged, not enough water is getting to the pump causing it to run dry.
  3. Check Skimmer Filter pad and clean it with hose.
  4. Pull pump out – Unscrew from Check Valve assembly (Turn off pump first!)
  5. Use screw-driver to make sure nothing is clogging impeller and impeller moves freely.
  6. Check Ground Fault Protection (GFI) – push button to turn power on . If trips again, water has worked it’s way through the seals – pump is probably shot
  7. Check for broken parts (Volute, etc) on pump and call us to replace broken part.
  8. If still dead, call us at 805-241-0141 – we can have a new pump to you in 1-2 days as we ship from 8 locations throughout the country. Keep in mind that there have been some pretty dramatic improvements in the energy efficiency of waterfall pumps. Check out Aquascape’s Aquasurge pump if you want to reduce your power consumption.

    Feed regular fish food when your POND WATER temperature is over 55 degrees and Wheat Germ Spring/Fall food for when the WATER TEMP is between 45 and 55 degrees. They will eat but cannot digest the food at those temperatures.
    Ponds with Koi have to run 24/7. It is espoecially important to run the pumps at night as well as that is when the fish are most in jeopardy in the oxygen cycle. I am not an expert on breeding fish but they need to bounce around in plants and rocks during the mating season. My 6,000 gallon pond gets completely covered in eggs for a week or so and it smeels like fish eggs everywhere. I have not had babies in 6 years as they eat the eggs like candy but that’s cool cuz I have more fish than I should any ways. I have 32 full grown koi in 6,000 gallons which is probably a bit much even with all my extra aerators, waterfalls (7) and filters. We have no catalog – all 4,000 items are on our site. We do not sell fish.Please call me aT 805-241-0141 for more info.

    Bad news – sounds like it is fried. Made by Performnance Pro. You could try to contact the manufacturer or order a new one at

    My pump is working fine, but the pressure is very low at the top of the waterfall. So the problem is between the pump/hose connection at the output tank and the intake tank at the top of the waterfall. Is there a snake, or what should I use to determine if there is blockage in the 25 ft between bottom and top?

    Have you checked the flapper in the Check Valve assembly? Sounds like it may have broken off and is floating loose in the throat of the check valve.
    Happens way too often.
