When and how to replace the filter pump of your pool?

09 March 2018

he performance of technical equipment may deteriorate as a result of wear and tear and ageing. This also applies for filter pumps. In this blog, we will explain how you can determine whether your filter pump needs replacing. We will also give instructions for replacing the filter pump.

This blog deals only with Speck filter pumps for swimming pools of the Badu 90 series. For pumps of different series, more or less the same procedure will probably apply, but this should be checked with the manufacturer.

For clarification purposes, we have also included an overview of the available filter pumps, indicating the swimming pools for which each model is suited.

When does your filter pump need to be replaced?

The lifetime of a filter pump depends on various factors. However, a swimming pool pump is expected to last, on average, for 8 years.

When a leak occurs between the motor part and the pump housing, the pump needs to be replaced. Such a leak cannot be repaired.

If the filter pump is seized up and produces more noise after you have reactivated the pump, then the ball bearings of the filter pump are worn or broken. In this case, too, the pump needs to be replaced.

The thermal protection of the filter pump may fail, which in itself is not a problem. However, if the thermal protection repeatedly fails over a short period, the pump is worn out. Again, the only solution is to replace the filter pump.

How to replace your old filter pump with a new one?

We have also included a handy checklist for replacing your filter pump.

  • First of all, make sure that the system is no longer running, i.e. disconnect the power supply to the filter pump.
  • Then fully close all equipment valves.
  • The third step consists of disconnecting the old filter pump. You must unscrew the PVC parts both at the front and the rear.
  • Then remove the old filter pump and install the new one according to the instructions provided with the pump. Make sure that everything is watertight. The PVC material must be sealed with adhesive and Teflon.
  • Fill the pre-filter of the filter pump with water. This is necessary to prevent dry running and possible destruction of the pump.
  • Finally, repeat the first 2 steps in reverse order. Open all valves again and restart the system.

As you can see, replacing a filter pump is not all that difficult. Still not sure? Then ask your pool builder to replace the pump.

Swimming pools for which these filter pumps can be used

An overview:

Single-phase versus three-phase:

This distinction depends only on the type of network that is installed in your home. If it is three-phase, then you should choose a three-phase filter pump. If it is single-phase, then you need a single-phase pump.
