We use flow meters to continually monitor the flow of water through your system so that we can determine when the filter requires backwashing and advise you

If your system is not fitted with an automatic backwash system, we will alert you via a text or email message that backwashing of the filter is required. When this happens, please go to the filter and take a Smartphone or Tablet with the Pool App on it. It will guide you through the Backwash Process.

Please backwash within 1 week of being asked.

The process is typically as follows:-

Pool App screen shows:

Backwash required, press READY TO BACKWASH on the Pool App. screen when you are at the filter.

Please rotate main valve on top of filter from FILTER position to BACKWASH.

If there is a valve in your backwash line, open it and press READY when done.

Please wait. Pump will now start and will backwash automatically. This will take up to 2 minutes.

The App will show BACKWASH IS COMPLETE. Please rotate main valve on top of filter from the BACKWASH position to RINSE and press READY when done.

Please wait. Pump will now start and will rinse the filter automatically. This will take 60 seconds.

Please rotate the main valve in top of filter from RINSE to FILTER.

If there is a valve in your backwash line, close it and press READY when done.

Thank you. Enjoy your pool.


This process is normally required every 6 – 8 weeks during the swimming season…and less frequently in winter. Alternately we can offer to install an automated backwash facility for a standard sand filter at an additional fee.

Please do not backwash more often than we ask.  Contrary to popular opinion, backwashing the filter regularly does not improve its filtering ability, but makes it worse.  There are two reasons:-  Firstly, each backwash degrades the sand converting the sharp edged grains that catch dirt well, into tiny rounded spheres that do not.  You will destroy your filter media quickly if you do this and you will then be wasting energy, water and chemicals. Secondly, filters actually clean better when they are slightly to moderately dirty as the spaces between the grains of filter media become narrower and filter finer. Backwashing very 6-8 weeks in summer is usually all that is required.

If you backwash manually, please rinse for a full minute, afterwards. This is important for keeping the downstream water quality sensors clean.

Please note that the pressure shown on the filter pressure gauge will usually be much lower than what you have been used to prior to the installation of the Pooled Energy system. This is due to variable speed pumping.
