having lost two toy cars done the bath out flows and past u bend have had to use hacksaw. I now have to refit new pipe and am lost, very lost. On bath side i have a thread 1 5/8" interior diameter, guessing that is a 2" pipe? On waste side have metric 400m diameter pipe. How do i conect the two, there was a kind of soldered plastic conection that i had to hacksaw through before.
