Grundfos Shower Pump

Power shower pumps from Grundfos



This pump has been discontinued.


If you have one of these and need to change it you may do so with most 'Positive Head Twin Impellor' pumps. Do not be too concerned if the replacement looks different, most will. Just ensure you have sufficient space to install an alternative.

Changing make and model is not normally complicated. You will have four hoses (two coming from the gravity hot and cold supplies, two feeding out as boosted supplies) and an electrical connection (which should be installed in accordance with IEE Regulations).

Whilst the process is regarded as fairly easy you should not undertake any work involving water and/or electricity unless you are fully competent and able to do so safely.
