Thought you might like to see some general views of the completed 'fixed' install. Remember I specifically provided a cupboard much larger than the architect said was needed, and larger than the builder said was needed, so that everything would be laid out tidily and easily maintainable.
Out of interest, what are your views on how accessible tundish and filling loop need to be?
There's no line of sight such that the whole tundish is visible (you can see part of it with one eye you stick your head in the right place). You could see it looking vertically straight down at the back with the help of a mirror or camera, but then won't see if it's discharging. You can actually reach it easier than seeing it - I can grope around and stick a finger in it blind, so could stick a finger in to find out if it's discharging. That's not a great idea if it's discharging 95C water because a temperature discharge valve has gone off, of course.
The cylinder manual says "The tundish must be positioned so that it is visible to the occupant" - does that just mean 'not completely concealed behind the bath or under the floorboards', or does it mean actually clearly visible?
Filling loop, you can reach the valves without too much straining, but it's behind several of the pipes and actually disconnecting it would require a degree of contortion and/or double-jointed fingers. Does that matter?
As for at the boiler end of things, someone is now taking the ****. I have 40mm internal condensate drain:
I've given up over the condensate drain. When the 'professionals' have cleared off I'll do it myself (see - thread is on topic) in 21.5 mm solvent-weld.
