Hi All
I've had some really good advice from the Plumbers about installing a shower.
I have reposted their responses below, 'cos the final question is more electrical, and is concerned about connecting an "all in one" shower unit (pump and controls in one wall mounted box). Is my thinking correct that I can use something like Screwfix 14770 to connect via a mains spur in the landing airing cupboard?
Thanks

--------------------------------------------------------------------------------
Been asked to install a shower in mother in laws.
System is a none combi, with cold feed from loft tank (so hot and cold at same pressure).
If I was to recommend a good thermostatic mixer (any recommendations?), could I just not tee off existing hot and cold supplies in bathroom?
Or do I have to get involved with essex flanges?
Thanks.

Can you explain the "new supply from the cold cistern"?

you need to balance the feed pressure so normally shower has its own supply from the head tank feeding the cylinder

Hi Kevplumb,
OK, I understand the reasoning.
What is thge best way to connect a supply from the cylinder feed tank? Do you actually tap into the tank (is there a fitting to do that?), or feed off the line out of the tank to the cylinder, i.e. into the existing pipe?
Thanks..

tap into the tank preff lower than where the cylinder feed comes out
hot runs out first

If it's from the loft to the floor below, you'll have a piddling shower unless you pump it. Easiest is probably a pumped box-on-the-wall like an Aqualisa Aquastream (£300+) or a Mira (£less) or a NewTeam (£130?)

Thanks for the suggestions.
If I was to go with an "all in one" solution, which was mains driven, would I need to get a sparks in to install it on a dedicated RCD at the CU. Or can they run of a spurred FCU /RCD, so in the airing cupboard on the landing?

my error and as I relise you meant the RCD flex outlet rather than the carpet tape, er yes of course you can, actually the RCD part isn't compulsory, but I'd recommend it in a modern installation!
