Troubleshooting Tips For Your Pond Pump

Pond pumps made in recent times tend to be very reliable and energy-efficient, with innovations in technology constantly improving the standard every few years. A pond pump supports the work of filters such as the Evolution Aqua Nexus 220. However, just like any other mechanical device, there may be issues that crop up on occasion. The good news though is that pond pump troubles are often very predictable, and you can solve the majority of pump failures on your own by simply doing a check off a checklist. We have put together a list of factors for you to observe and test on your own in case of any mechanical failure, before you need to contact the pump manufacturer for assistance.

Check Water Flow To The Pump

The first thing you should check in case of any issues is the most basic: water flow to the pump. In fact, this is the most common cause of pump issues thus far. The water flow may have been cut off by debris, leaves, a large rock, a clogged skimmer net or opening, or a jammed skimmer flap getting in the way of the water flow. All of these isuses can cause problems with the water getting through to the pump. Sometimes also the pond water levels might be low, which prevents water from getting into the skimmer box. Take note that between the plumbing, your filter/waterfall box, and the waterfall itself, the pump will drop the water level to some extent when it’s running. Though the skimmer box may seem full when the pump is disconnected, once it starts the box runs dry or nearly dry.

Check If Your Pond Pump is Vapor Locked

Another possibility is that the pump may be vapor locked. This happens when an air bubble is trapped in the main internal space of the pump, called the volute. Though the impeller may spin, it won’t be able to move the water due to the air bubble. If this is the case, a solution is as simple as tilting the pump underwater so the intake is upward, which allows the air bubble to escape.

Check Electrical Flow

A simple thing to check would be electricity flow. Test the ground fault and circuit breaker to be sure that neither has tripped. You can test using other appliances on the same power outlet.

Flush Your Plumbing

By simply disconnecting the fitting above the check valve, thereby letting water flow out of the system and back into the skimmer box, this can wash out any clogs that may be stuffing up your plumbing.

Inspect Pond Pumps For Debris

There may be some debris or a rock which has gotten into the pump and is blocking the impeller or intake. Clean it out and make sure it’s clear.

Jumpstart Your Pump

If your impeller isn’t spinning, you can try to jumpstart it. Unplug the pump and carefully bump the impeller with a screwdriver. This should knock it loose and allow it to spin freely. Plug it back in; if the impeller is now spinning, unplug it again and re-install it. In the unlikely event that you have gone through this entire list and your pump is still not working, you should get in touch with your manufacturer – or get a new, and better, pump!
