With tiresome predictability there's a faint whiff from our kitchen sink again.
It will be because there is a flexible concertina type connector between the middle half-bowl and the main bowl that manages to trap crud and presumably ferment over time - naturally above the trap. It has to be flexible because there's a height differential between the outlets.
Anyway last time I asked for advice someone suggested an inflatable bung to seal the pipe and then fill with something to leave overnight.
Returning to that theme, I find myself wondering if there exists some sort of valve I could fit to the outlet pipe (40mm) such that I could seal the pipe, add the bleach/whatever and leave it overnight.
A brief google suggests:
Once again, it's a question of names :)
Does such a thing as a valve for the 40mm waste outlet pipe of a kitchen sink exist ?
Thanks in advance :)
