Our sink, washing machine and dishwasher all drain out through a U-bend, then a 90 degree compression joint, which brings it to a horizontal pipe. There is then a 135 degree solvent weld turn to align it to the hole through the wall, outside there is then a 90 degree solvent weld downturn to a four foot length of exit pipe which goes into the drain.
The horizontal length of pipe going through the wall blocks up and takes most of an afternoon to clear with various bits of old hose pipe, coat hangers and whatever else I can find to poke up there.
If I were to add a straight coupler near the top of the four foot pipe outside, I'd be able to easily get in there to clear it.
I measured the pipe and it appears to be 44.5mm diameter which looks suspiciously like 1 and 3/4 inches, but everything I can find in the diy stores is 40 mm.
I decided that I'd try a push to fit straight coupler, but there is no chance that this would fit.
I now notice that some retail outlets show the compression joints as "universal": does this mean that it would fit my 44.5mm pipe ? Or do I have to get rid of all the 44.5mm pipe back to the U-bend ?
