How To Repair A Frozen Pond Pump Impeller Wont Turn

How to trouble shoot your pump issues

There are a few reasons why a pump could be playing up. In this blog we look at the means in which y'all could problem shoot your pump issues. Nosotros will teach you how to Do It Yourself, specifically:

Learn how to do the famous Burn Out Exam
Learn how to change the impeller of your fountain, pond or waterfall pump

Let's get started:

Offset you need to cheque if the pump or the impeller is clogged and therefore non letting any h2o flow through freely.

Switch off your primary power supply. Accept the pump out of the h2o for inspection. You may need to disconnect the pipage, but ordinarily this won't be necessary.

Clip off or disconnect the forepart filter/ strainer from the pump housing. (Meet arrow 1) You may accept to use a bit of force as the pump has probably been submersed for some fourth dimension now. You can practice this past slightly tapping the pump against an object, or using the handle of a screwdriver. Therefore bumping the forepart end filter/strainer off or abroad from the strainer until dislodged.

You volition then have admission to the volute. This is the round plate that clips or screws into the impeller housing on the pump. This is too where the water inlet for the pump is. Y'all will turn the volute (Meet arrow 2) anti-clock wise until the volute comes abroad from the housing. This may take a bit of force again as the pump has been standing in water for a while. Y'all can use leverage to turn the volute if need exist, just exist aware that too much force may break the volute instead of but loosening it.

Once this has been done you will expose the impeller, shaft and rubber washers inside the pump impeller housing. The condom washers will be on either cease of the shaft (See pointer three) One will be lodged in the plate that y'all accept only removed and the other should be lodged in the bottom of the impeller housing. These are used to secure the shaft in place, to ensure smooth spinning of the impeller.

The shaft is either stainless steel or ceramic and needs to exist checked that there are no wear ridges forth the shaft. Delight annotation that is your shaft is ceramic, that care is taken not to drop the shaft as they are fragile and will suspension.

Besides be aware that on opening the housing and exposing the impeller, that the rubber washers don't drop out into the h2o without you noticing them. These are essential in allowing the magnet impeller to fit smoothly and securely inside the chamber.

You tin at present slide the impeller out of the bedroom for inspection (Run across arrow 4). At that place will be some resistance to this due to the magnetic strength. Once out, hold the impeller in hand and visually audit that any of the fins on the plastic bicycle are all intact.

Concur the magnet in ane hand and with your other mitt rotate the plastic fins effectually. They should plough about 340 degrees so finish. Contrary this action and they should stop again.

If the fins rotate freely 360 degrees effectually and tin go on rotating without stopping at a bespeak, then this indicates that the impellor is worn and needs to be replaced. Please make sure you reassemble the impellor into the pump advisedly, and that all pieces are replaced.

If the impellor, once tested for faults, is intact and then the next stride will be to test that the pump notwithstanding has power and has not burnt out.

By doing the same as explained above, remove the impellor from the pump. Hold the impellor in ane hand and while the pump is plugged into your power supply, move the impellor shut to the pump. If there is a vibration felt from the impellor magnet while moving the impellor close to the motor, then yous know that the pump has non burnt out chip simply needs a new impellor. If still the pump is dead and there is no vibration felt, and then the pump is burnt out and depending on the warranty, tin can be replaced for a new unit.

Y'all can too do a visual inspection of the cable to see that the cable has not perished or is not broken anywhere along the line. If the cable is damaged, then this can commonly be fixed and so long as the cable is not broken too close to the pump. There should exist almost 1 metre of cablevision that is still intact, to make joining a new cable feasible. A waterproof cable joiner tin can exist used to join the cable properly.

TIP

Keep the pump from lying direct on the floor of the pond past suspending information technology on a brick or a rock. This will stop the debree that is on the pond floor from being sucked directly into the pump. This tin can lead to the pump blocking or clogging up quicker than normal.
