adding ensuites water supply

[njkmr]

Hi Good Morning
I am adding two bedrooms and two ensuites in my loft space .
Will I be able to tap into the water supply of my existing bathroom downstairs to feed both ensuites for toilets,showers,sinks.The pipe downstairs is 15 mm I think and the pressure is good .
Many Thanks for your guidance .

Yes you can, but your pressure will still be affected going from the downstairs to a loft even if it's good, because it's quite a way, and especially feeding 6 appliances if you are fitting a toilet, basin and shower in each.

My advice is to extend your rising main into your loft and branch off, that is of course if you are on a direct system, that way you won't really lose any pressure.

Thanks John .
I am not sure if that is going to be possible to be honest .The supply comes in to the garage under the house and then under the hall floor which i have recently tiled and then into the bathroom,on the ground floor .It then goes up to the bedroom ensuite upstairs which is where I was hoping I could get my feeds for the other ensuites .

as you say get your feeds from the ensuite below.
what type of system do you have is it a combi etc ?

I have a worscester 32 i combi boiler .It should be able to run two showers shouldnt it .? As well as my central heating with about 15 rads in total .
Again the showers probably wont run at the same time .
