Hi again

I'm putting plumbing it for a power shower (again!).

As I can't get easy access to the floorboards I'm thinking of just
laying the pipes from the airing cupboard into bath panel space
(which is just behind the airing cupboard) hook up to the pump and
then on to the shower cubicle in the next room but parallel to the
bath.

The pipes would run along the the top of the floorboards (out of sight
though as they'll be in the bath panel void).

Is this acceptable?

Yes


As the pump is in the beneath the bath in the void area, is it ok to
run the electric back to the airing cupboard to be connected up (by a
pro sparky, I'm well aware of Part P)?

Yes


I spoke to salamander and turner pumps companies and they both say
22mm must be used as inlets for a power shower, would plastic pipe
and push fits be ok for ?

Probably. 22mm plastic has a slightly smaller internal diameter than 22mm
copper - particularly the inerts - but it's still probably ok


I know that I can't use plastic push fits
near the Sussex flange due to the heat.

Why? You can't use plastic pipe within a certain distance of a *boiler* -
but a hot cylinder is only as hot as the water in it - which is eventually
going to flow through your plastic pipe, anyway!
