hot feed to bath

[nickdc]

I have a 22mm hot feed coming from a Fortic F1tank housed in the bathroom cupboard going to my bath, i want to change this to 15mm the same as the cold. The hot pressure is not good anyway but would it get worse by changing it to 15mm, cheers

It'll be hopeless leave it at 22mm.

Why do you want to change it ?

Im not a plumber, but why do you want to change it.
info..The pipe size is flow related not pressure.

I've got an old rolltop bath but i want to hide the pipewok behind some timber cladding and the 22mm pipe is in the way and it would look better with two 15mm, would it drop the pressure by that much?

Not the pressure but it would negatively affect the flow rate, as already stated bad idea, don't do it
