Shower Pump

[rubble2]

We have a shower in the en-suite which is supplied via a pump (gravity fed system with hot water cylinder in airing cupboard). The existing shower pump is supplied with cold water from the storage tank in the loft, presumably to equalise the pressure for hot and cold supplies.

We want to install an over bath shower in the main bathroom and the easiest way would be to utilise the existing hot and cold feeds under the bath but the cold water feed to the bath is direct from the mains.

Is there any way of doing this (some sort of pressure reducer?) without the problem of running a cold water feed from the storage tank?

Thanks

Is it a single or a twin impeller pump you have? I'd guess it's a twin fed from the cold cistern in the loft and the hot water cylinder to the en-suite shower only?

It is a twin impeller pump as you suggest, but the existing pump is installed in the airing cupboard right next to the en-suite. The main bathroom is across the landing so I am looking at putting a second pump in there, under the bath.
