shower pump

[lilynmax]

i have just moved to a house where the bathroom has recently been refitted, however the shower is not very powerful. i have an electric shower and want to know if i can add a pump to it without having to redo my bathroom? the water tank is next to the bathroom, on the other side of the wall from the shower.

You can very probably do it, but it may not have the desired effect that you think it will. These electric showers vary their temperature of the shower water by varying the volume of cold water passing the heating element inside the shower.
Let me ask, if you turn the temperature down on the shower control, does the flow of water increase to a more acceptable 'power', to use your term? If the answer is yes, installing a pump to the input side won't alter anything. You are being limited by the capacity (in Watts) of the electric system to heat the water from cold to shower-hot.

If the Shower is mains water fed which is often the case in electric showers then i do not know of any pump you can run from the mains. But if it is fed from the Header Tank then yes it will boost the pressure especialy if there is very little head. But as buildersmate suggests it may not have the desired effect.
