22mm plastic to 32mm plastic connection

[old duffer]

I need to connect a 22mm plastic pipe carrying condensate waste (boiler already neutralised it) to a 32mm plastic pipe than will then fit into a 4 boss waste manifold
Any suggestions?

so tried this today.
fits inside 32mm pipe but where does the 22mm pipe insert into it?

21 mm overflow should fit perfectly,have you got it the right way round

Is your pipe White, known as white waste overflow pipe.

i use 22mm regular plastic pipe to take the condensate down 6 levels to outside.
I have fitted a new soil pipe in a bathroom and can now terminate the condensate at 3 levels down instead of 6 and straight into the sewer rather than an outside drain
I need to connect the 22mm plastic pipe into the boss as described but to avoid sewer smell leakage, I wanted to use a 32mm pipe into the boss as the boss has a rubber seal for 32mm
hence the 22mm pipe to 32mm connector question

Then the regular 22mm pipe should fit in the centre if there are no burrs on the pipe.
