There must have been a reasonable run for the bath waste when it was new
what has changed (the bath has been turned around 180 so the plug is not
near the waste? - Odds on I'd say).

I don't believe ours could *ever* have worked well. Bothe bath and
washbasin have long near horizontal runs.


Let me guess further we are talking about a 1970s flat, give or take, with a
silly set of tanks holding water to give about 0.05 bar at the kitchen hot
tap on a good day.

Well ours is 1960s I think, but near enough.


Combi boilers are the solution, or if no gas, electric unvented.

Yes, that fixed our 'feed' side problems very elegantly.
