Help joining 40mm pipe to 32mm?

Hi. My plumber fitted a waste from my sink to an existing outside pipe. He joined them using a 40mm 90 degree connector (corner of the house) but I have since realised that whilst his pipe is 40mm, the pipe it is joining to is 32mm and so leaks and will not stay connected.

Is there an easy way for me to join the 2, such as a 40mmx32mm 90 degree connector? Have searched google but can't seem to find anything. I also thought of some kind of rubber washer on the 32mm pipe to make it 40mm but again can't find anything.

We have fallen out with the plumber so can't get him back to fix and would prefer not to hire somebody else.

I am no expert so would appreciate any help and advice.

Just get reducer.

You can get the same in solvent weld too.

just use a 40mm bend and stick one of these in the outlet with 32 mm
