Belfast sink - joining old waste to new 40mm trap and pipe

[Spectric]

would look quite odd and misplaced on the main pipe run.

Then place it behind the sink unit on the wall, direction is not a problem as it does not have to remain in the 180 degree plane, you can use them as a 90 degree bend.

dont forget the toilet will probably have to come out to give enough room to remove the old pan connector and get the new one in

For the benefit of anyone coming across this in the future who finds themselves in a similar situation - and for the benefit of closure! - my plan changed again!

Someone recommended this:

https://www.wolseley.co.uk/product/mcalpine-t12-bsp-female-x-male-couplng-15-x-1-25/
I ended up getting one of those and did the following... From the sink plug hole:

- 1 1/2" - 1 1/4" coupler reducer with flat washer, as per link
- 32mm telescopic P trap
- Connect to existing pipework (which is 32mm)

It's all working great.

Thanks one and all for the help, very much appreciated.

never realised a reducer like that is available. stored in memory for future (but probably will be forgotten if I have need of one !)
