FLOPLAST 40mm (43mm) Waste Pipe Fitting to Overflow Reducer - Pack of 2

Product Information

Do you have to 'stretch' a 40mm compression washer over the 43mm pipe, (looks like it would be pretty tight!), or is there some other 'proper' way to do this? PF Community Forums General Off-Topic Chat For Sale & Wanted Make a suggestion about the forum in general

Solvent weld a 43mm waste pipe to traps from the sink, shower, washer or more, to create secure wastage systems. Be sure to make sure your pipe size is the same as that of your sink waste trap to avoid any nasty leaks. I guess firstly, to remove the joint i think i need to saw off the pipe at the joint which would result in a smaller pipe out of the wall. As such, i would struggle to make the pipe reach the drain if i then replaced the 90° joint. I may be being think and there is a simple option but im loathed to replace the full waste pipe configuration as the pipe from inside to outside is cemented through the wall so would require more work than im probably capable of myself. Create a secure waste system with solvent weld pipes and other waste pipes fittings. Solvent weld fit runs have the most extended lifespan of all waste systems, including push-fit and compression systems. Pipe should come out of wall fairly easily, could use multifit joiner T28M inside to connect from old pipe to new 40mm pipe.Secondly, i just cannot find a standard 90 degree joint that has a suitable diameter of 43mm standard. All seem to be 40mm. The plumber fitted a new boss and pipe rununder the floor, surfacing underneath the bath, all in grey solvent weld pipe, which according to the 45 degree elbow (has stamped on it) is 43mm pipe. quote="plumbbob"]There are one or two odd sizes of pipe about, and solvent weld is usually larger than std 40mm. Compression style couplings usually cope with a larger size of pipe as well as allowing for a slight variation of angle joint.[/quote]

My question is whether this 43mm plastic pipe can fit to 40mm pipe using a (presumably) 40mm joint?
