It must be directly from the cold tank and not the mains. Don't let
him bodge it by tapping into a pipe in the airing cupboard.

The hot take off should be from the cylinder using either a separate
tapping or a Surrey or Essex flange on the cylinder.

Otherwise the shower, even though thermostatic, will tend to pulse hot
or cold as taps are turned on and off.

Ahh - that rather destroys an idea I had for solving my weak flow
problem !! Single story cottage, head is 4m max. so it's been an
electric shower for many years, with the annual mutterings in the mid
winter about poor flow (winter water temperatures in Scotland tend to
be a bit low !). The mutterings were usually ignored, until recently
when the other half came in contact with one of those kitchen mixer
taps on a shower hose and came proudly out of Homebase clutching one
pleased that she had got it on a 10% off day.

Muggins fitted it without reading all of the small print - those who
have read the small print, or are muggins too, know what I am talking
about - these taps have a high insertion loss and the hot water is a
piddle now.

So, as the shower and the kitchen sink are physically close I have
been thinking that I could kill the proverbial 2 birds and fit one
pump. Do I take it this is not a good idea ?

You can't put a pump on the mains.
