I've recently moved house and inherited a bit of a mess of dodgy DIY stuff (and it's bad when I, the master of dodgy DIY, consider it dodgy).
Having just plumbed and fitted an upstairs bathroom, with many thanks for some good advice from the group, I've discovered the shower in the downstairs bathroom is fed from the water tank.
I've always understood that an electric shower had to be fed from the mains supply. The question is, is this just an annoyance to be sorted when time permits or is it a danger which should be sorted as soon as possible?
The flow rate is poor, understandably, but just about acceptable which is probably due to the shower being on the ground floor and the tank being in the attic above the first floor i.e. about a floor and a half above.
Second question - should an electric shower be plumbed with 15mm or 22mm pipe?
