The hot water flow could be made a bit better with some 28mm pipe for as
much of the run as is possible before connecting to the tap.

That's useful information - though not for this particular job. Reason
being the structural arrangement. It's currently fed from 22mm so I
would guess the 28mm would only be marginally better.

The 'feed' side of our flat has been improved since the old system was
completely ripped out and a boiler with a flue fan installed. This
means that the boiler is now in a much more sensible position than the
old one and the feeds from it to the bathroom etc. are reasonable.


Also, is there room for a clamp on boss under the branch on the main waste
stack ?

As above. I'd have to tear down walls (or at least give them some
serious treatment with my SDS drill) to get to the stack. I don't
precisely know where the stack is in this flat, though I have a
suspicion it is probably at the back of the airing cupboard - with 2
large water tanks in front of it (and 5 control valves with pipe
running in different directions) so I'm not about to expose it.

Yes, as I said earlier in the thread, this is exactly our problem.
The waste stack is in a brickbuilt service duct which is very
difficult to access.


The clamp-on boss suggestion is good idea though!

Just can't understand how any plumber could get away with such an
installation! It would have been so easy to fix these problems at
build time. I'll bet the original site manager wasn't up to speed on
this development.

Our 'piece de resistance' was the junction-box/timer for the bathroom
extract fan. It's in the service duct well out of reach of either of
the access panels. It must have been put there and wired up as the
service duct was built as there's no way you can get to it now.
