Fitting bath taps with 15mm supply

[ibbero]

I am about to fit a new bath in the ensuite, but the water is fed by 15mm copper. Will it be OK to feed the taps with this supply?

How is the hot wate produced?

Combi boiler?

Gravity cylinder?

Unvented cylinder?

Yes if you have a combi or mains unvented cylinder.

No if you have a gravity fed open vent HW cylinder. Baths should be fed with 22mm in these instances.

I have a gravity cylinder and apparently I am informed by "Gas4U" that I need to use 22mm

Thanks for the info. I have a gravity-fed boiler. Does it mean that I have to have 22mm all the way from the boiler?

The 22mm pipe should be from the hot water cylinder to the bath tap. The boiler is a seperate issue and wouldn't come in to this, unless you are calling your cylinder a boiler
