How to attach 35mm brass bottle trap to solvent weld 40mm waste pipe

[JEd1]

Hi,

I have a brass bottle trap - see photo. 35mm.

I’ve got solvent weld waste pipes and now struggling to work out how I fit the two together.

I may have jumped the gun here when I bought it and not thought through whether I can get them to fit!

Thanks

You’ll be needing one of these

You can't connect this directly to a 40mm waste pipe.

You'll need to reduce the pipe size too at a convenient point, looks like you've got 40mm (1.5") waste pipe there, Basin waste and trap will be 32mm (1.25").

Presumed it was a 32mm waste given it was a basin trap, ah well

You presumed correctly as McAlpine only produce their adjustable plated bottle trap in 32mm size

If you zoom in on the R/H pic, the vertical section the OP wants to join to is 40mm, so it will need reducing somehow.

Yeah, spotted that 2nd of looking, I should know better that to assume anything on here without checking.

The heading of the thread tells us it's 40mm solvent weld pipe.
You need to reduce that to 32mm, as already advised.

I’m on holiday and beer at the pool can be a bad thing when it comes to IPads, the sun and trying to read the screen properly

I think you'll find the McAlpine compression 32mm female will fit yer metal pipe. You may have to remove (penknife) the internal pipe support which you don't need and will be in the way
SO one of these to gfo from metal to 42mm
