Just done this ourselves.
Pressure to existing hasn't been affected, we have one water meter and branched the new supply nearer to the meter.
This supplies additional boiler, washing machine, DW, sink & full bathroom.
This is an annex for family so we are paying the water anyway.
There are two on the 1st floor as well (only leaking a small amount) I can see the window boards are blown along the back edge and damp & raised on the edges.
If I (he, probably or I'll keep the outstanding balance) can do the work as you suggest but inside & out without having to take off the...
I'm happy to remove all of the interior plaster on top & sides, we haven't had a chance to re-decorate since they went in anyway so no issue with another re-finish.
Thanks for the link :wink:
So, if I rake out and seal all around the inside where the plastic meets the wall inside...
The sealant on the outside edge has only been there about a week as an attempt to stop the leaks until the windows can come out again for a complete sort out.
Yesterday the sealant was taken out, still dripping into my bucket!

Hi Gazman16
Some interior and exterior images for you.
Today I took out some interior plaster for a better look. I can see water ingress on the inside of the outer cavity wall, trying to re-route it until the builder can get back....

Thanks Gazman 16
I suspect it needs to be sealed on all 4 edges like this?
I'll take pics in the morning.
The cill for sure hasn't any, otherwise I wouldn't see the blue dye.
before I found it coming into the cavity, the window board was wet in places, far too much to be condensation.
Hello
I have water dripping from the left & right of the cill (sill?) into the cavity.
The plaster was damp so I removed the window board to take a look.
Drip drip constantly during rain so I have put a pot at either side with paper towels moving the water over a plastic lining into buckets...
