I have a drain pipe underground, in the garden, which I have access to and need to block off.
I need a blocking thing, of which there is already one fitted elsewhere.
It is to block a pipe about 4 ins in diameter and apparently has a rubber bit in it, which when the device gets tightened, squeezes the rubber which expands and blocks the pipe.
I need to know what the proper name for these pipe blockers is, and if poss, where I can get one in the UK.
Thanks
CJ
