I am installing a new shower (Aqualisa Axis Digital) that incorporates a small pump and requires 15mm supply pipes. I have received conflicting advice regarding hot water supply and would appreciate advice on the following:-
1) The simplest solution appears to be putting a branch in the HW vent pipe, close to the cylinder. This is 28mm so is it OK to fit a 28/28/15 tee?
2) Is is better to fit either a Surrey or Essex flange to take water direct from cylinder (although I can't see real benefit in doing so)?
3) Is there another option?
Many thanks
