I want to know if there is a way I can join UK soil pipe into soil pipe
from another country. The soil pipe from Thailand is about 1/8in bigger
in dia than the UK pipe, hence UK pipe fits into a Thai coupling with
about 1/8in gap. Seems to big to expect gap filling solvent to glue
this. I did wonder about the fibre glass repair kits for cars, the
stuff with chopped fibres.
This is to join a bottom drain (from the UK) for a Koi pond to be built
in Thailand.
