Our handbasin waste pipe is a 28mm OD copper pipe. That is, the pipe that comes through the floor is 28mm. What's the best way to join a
32mm plastic to it so I can them use a plastic trap? Will just putty do? That's what seems to be there now but it look horrible and I don't know how reliable it'll be. It's quite a large gap to seal with just putty so I've looked for copper to plastic adaptors but no luck yet with the sizes involved.- posted
