Can i switch to cold water mains for upstairs taps

[marc1977]

Hi,

sorry another question, im replacing my cold water tank and was wondering if there are any reasons not to switch the upstairs cold water taps to mains water rather than an indirect tank feed. The cold water tank feeds 2 taps and a shower. I have a mains pipe very close so would not be a big job. Any advice much appreciated!

Thanks

Marc

The thermostatic balance on the shower would be upset by mains pressure cold water. Outlet from new tank to shower needs to be lower than outlet to DHW cylinder to protect against scalding.

If just for the taps, cant see any problem.

Pointless though if he's keeping tank for the shower

it does also supply shower which just has a manual tap mixer . this should work with mains pressure though?

No. Because your hot water is coming from a gravity fed system you'll have unbalanced hot and cold feeds which you really, really won't be happy with.

ok thanks cropple. would a pump on the hot water feed fix the imbalance?

 

[Riley]

It's unlikely as you'd struggle to balance it

Agreed, it'll cost you far more botching it than it would to get the job done properly.

Good idea to feed basin cold tap of mains, would leave bath and shower off roof tank.
