(ie the old pipes will not fit into modern solvent weld fittings for 43mm and 36mm)
I am sure of the measurements. Are these some old weird Imperial size since metricated to 43mm and 36mm or has the old pipe swelled with age?
According to this lot the pipe size I have encountered does not exist!
If Imperial they would be ODs of 1 23/32" and 1 7/16" respectively.
Now for the gotcha - they appear to have push fit connectors on them and the sink waste takes an insane number (5) of right angle connectors to get from the wall to the sink. I dare not tweak it in case it is actually solvent weld, but the connectors on the pipe run look exactly like modern O ring seal push fit except for being about 4mm bigger!
Anyone recognise this size? I could in theory bridge the old and the new with a universal compression fitting but as ever space is tight.
My options as I see it are roughly to either find a compatible set of new fittings and pipe or redo the whole lot. I estimate that the installation was done in the late 1970's if that narrows the field any. How long does this stuff last?
BTW thanks to all for the tips on blanking off the supply pipes and getting the old bath out. I junked the taps in the end.
The old bath turned out to be nearly 10mm thick acrylic with a thin glass fibre reinforcement on a tubular steel frame with MDF baseboard and then surrounded by heavy wood subframe screwed into the wall by two hidden 2" wide stainless steel brackets that made it incredibly rigid. The latter only became obvious when all the visible fixings were removed and it still would not budge an inch!
