Installing a shower pump

[iaindunn04]

I am considering putting a pumped shower into a flat. the problem is the cold feed to the bath is direct from mains and the hot is from the hot tank.. Cant really install a seperate cold as the floors are concrete. Is it possible just to boost the hot side with the pump and supply the mixer tap with cold directly from the mains?

Yes, but install a one way valve on the hot supply. and you could also fit a pressure reducing valve to the mains supply to regulate the flow.

You could also consider using a "venturi" shower. These work by using the high pressure cold to boost the low pressure hot input. A search on the net should flag up a couple of makes.

Plumbworld do a venturi shower called h2o platinium cost about £100 with excellent performance and good looking with it.
