as far as im aware your not allowed to pump water from a combi - the boiler sets the pressure (well, strictly speaking its the mains pressure) and so its not viable to try to increase this pressure.

The pressure may have dropped because your water tank may have been in such a position as to give high pressure (ie high up!)

You also cannot change the shower to a power shower or pumped shower, unless you install a tank for the combi to fill, and the shower can them pump from that.
