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

[Plumb Line]

Hi all

We're having an old belfast sink fitted in our WC/utility room. We'd like to use the existing old waste; and by all accounts it'd be a pig's jacksie to remove even if we wanted to!

The threaded section in the photo measures approx. 1.88" / 47.8mm outside diameter and 1.24" / 31.5mm internal diameter.

The only thing I can think to use is something like this:

Swell Rubber Reducer

Rubber reducers for many pipe grades like PVC, waste and pressure pipes Made from a high grade EPDM rubber Various sizes available

www.swelluk.com

But whilst the sink out will be inside the reducer, which is good from a gravity point of view, the 40mm trap and pipe will also be inside the reducer which ain't so great.

So I wondered if there are any other options? Anything entirely different? Or something along the lines of the rubber reducer, but with a threaded connection on the smaller end to it connects to the 40mm trap and pipe properly?

I'll keep looking in the meantime.

Thanks a million

You’ve got nothing to loose other than a p trap and an adapter

For the benefit of anyone coming across this in the future who finds themselves in a similar situation, my plan (as outlined in post #25) worked a treat, and I'm set up and all works perfectly.

Thanks one and all for the great help. I wouldn't have got there without you!
