Potable water

[Stigster]

You can supply drinking water from a storage cistern provide you take account of a few things. In the UK water regulations, Clause R27.2 It states that wherever practicable drinking water should be supplied direct from the mains. However you can use a cistern if

a. The interior of the cistern is kept clean.
b. The quantity of water stored is restricted to a minimum essential capacity so that throughput of water is maximised.
c. The water is kept below 20C
d. It has all the relevant parts from the byelaw 30 kit
e. The cistern is regularly inspected and cleaned internally

Depending upon where you live and given that the cistern must be insulated it can be difficult in summer to keep the water below 20 degrees whilst also preventing freezing in winter.

Ultimately as others have stated, it is much more preferable to have the drinking water off the mains but it can be done when there is no other alternative.

We all know what temperature a roofspace gets to in summer , defo wouldnt be drinking out of tank fed supply

I have on several occasions in Bath years ago been called to top floor flats which had tank fed cold water supplied only to both hot and cold. Usually the complaint by the tenant was the water tasted odd when they brushed their teeth in the morning.
Solution was to remove the dead rotting pidgeon blown up to the size of a football
disinfect etc etc and put proper tank cover on . No tank fed drinking water for me my
customers or my holiday let people. centralheatking

If there is a tank fed cold in that position now, I would be trying to trace it back to a point where you can cut it and connect it to the mains that way there is no disturbance in the kitchen.
Obviously this may be more trouble than running a new pipe but often it is easier.

I presume the tank is mains fed, disconnect the tank and connect mains to cwds. Save cleaning tank out every year.

Possibly acting as a header tank for the DHW too?

Don’t do this!

Well I suppose you could if the tank is only feeding that cold water position, which I’m willing to bet large sums of money is not the case.

Run a new mains supply no way would I or my customers be drinking from a stored CW tank . Kop
