Bathroom P Trap Not Lining Up With Waste

[lost in espace]

We went away and the house sitter reported the bathroom sink was leaking. Turns out the waste and p trap didn't line up and the previous owner had bodged it in at an angle, the nut under the sink has become brittle and split and started to leak everywhere.

I have just bought a new waste but stand no chance of getting the trap and waste to line up. Any suggestions as the the best way to resolve? Hopefully my photos are clear enough.

You might need to cut off that 90 bend on the outgoing pipe & look for a S trap that is long enough to get from the basin to the pipe or use an extension piece if you can find one:

Remove the 90, shorten the vertical pipe and fit a flexi

Brilliant thanks for taking the time to reply both of you.

From your photos, I'm quite impressed the previous owner managed to get it connected at all!

OP if you use a flexi consider fitting a bottle trap as they are easier to clean out:

Looks to me like solvent welded pipe so that makes life difficult if it's be fabricated to fit a different waste position

I'd do this



Then use a joiner like this (sized to the pipe - I just picked a 40mm one)



to link the two parts and enable you to swivel the 90 deg bend

But that's just me!!!

Me too, but for compression fittings I would generally go for the McAlpine Multifit version as whilst they cost a little bit more they seal on both the inside and out, and tend to be a bit more tolerant of different pipe sizes (e.g. solvent weld pipes being imperial despite being sold under their nominal metric equivalent).

P.S. Worth checking it is not a 32mm waste (if so, this is the right one) as it can be hard to tell from a photo without scale

Agreed about McAlpine Multifit I've used those on "proper imperial" pipes (house was originally all imperial wastes) but only one is left now

Thanks everyone, I felt a daft plonker for posting this and you have all been so helpful!

You shouldn’t feel like that at all

Same, but I'd use a solvent weld connector. Yes you can't adjust afterwards but it should be a simple matter nonetheless.

If it was under one of my sinks I would too but I already have solvent and joiners - however in the case of the OP - I’m guessing he wants an easy fix (plus the compression joint will allow a little bit of height increase that you wouldn’t get with a solvent joiner

So it was my suggestion to keep it simple quick and easy

I always buy loads of parts and then return what I don’t use

In also have good results with flexi waste

Loosening the trap will allow some swivelling but it looks like at least one cut will be necessary.

As others have stated previously, the correct repair is cut pipe insert solvent weld coupling and adjust trap to suit waste fitting , about a one minute job
