43mm waste pipe fittings

    Hello,

    My outside waste pipe from the kitchen sink has a 90degree joint that has cracked and causing the waste to leak before reaching the main drain. I naively thought a simple replacement would be suitable however since found that the joint is solvent weld and has an outside diameter of 43mm rather the standard 40mm.

    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.

    Secondly, i just cannot find a standard 90 degree joint that has a suitable diameter of 43mm standard. All seem to be 40mm.

    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.

    Any ideas?!?!?!

    Any makers name on fitting, use to be a nightmare years ago with compability between brands.

    Usually push fit pipe had a OD of43mm, but check Floplast solvent weld fittings, sure they are larger than 40mm ID, closer to 43mm, & the old wickes was 43mm.

    See this link, might help. http://www.sanifix.co.uk/conversion_fittings.html

    This is the only marking on the equivalent 45° fitting for the same waste pipe

    Great thanks. How can you tell?

    That aspect aside, any thoughts on the issue about shortened pipe by sawing it down?

    Thanks for your help
