Got a bit of a tricky one here.
I'm trying to connect some new type PVC soil pipe and fittings to the
existing stuff in my house.
Its a concealed soil pipe in a 30-40 year old ex council house.
There is a T which has no seal..... and the pipe which comes into its flange
has a groove and an O ring.
The new pipe is 110mm O/D and the I/D of the T into the existing soil pipe
is about 133mm.
Does anyone have a suggestion on how i can get a proper sealed join between
these 2 different types?
