Mains cold water feed to a new electric shower.

[giraffe]

Hello. Is it alright to tee off from the cold water feed that leads up to the header tank in my loft?

I have a indirect vented system and I have mains fed cold water in the actual bathroom and a cold water feed up to the loft (and the tanks).

I'm guessing that it shouldn't matter, but I have experienced pipe vibration when running the taps in the bathroom.

I removed a non-return valve that I installed just under the shower unit and this seems to have cured the problem.

I haven't quite finished the installation and would be glad of any advice.

p.s. I am getting an electrician in to do the wiring. Thanks Giraffe

yes fit a seperate isolater for the shower tho

Should fit isolation valve along the horizontal pipe I have tee'd off from the mains feed in the airing cupboard, rather than on a vertical pipe leading up to the shower?

Not sure what you mean

Tee off the rising main and whatever you feed put an islating valve for future service.

That should have said "should Ifit ..."

That's great though thanks for the help!

I wont bother with the no-return valve as it seemed to be the source of the vibrations in the pipe.
