I have very low main pressure, can I install an electric shower?

Yes, most electric showers are designed to work from mains pressure, however if you have very low or fluctuating pressure you can install a plumed electric shower, example: Redring Expressions 570 Pumped Electric Shower or the Triton pumped electric showers.

Pumped electric showers are installed with the supply of water coming from a cold water tank, the pump in the body of the electric shower then keeps the flow of water at a constant flow, giving the perfect supply for the electric shower.
