Be sure to check the drain pipe.
Ruth gave me a shout this afternoon, when i was quickly doing some work for my course, the sink had stopped draining away. Now given the amount of junk we let go down our drain (we are very bad at picking all that rice out of the pan before we wash). I don’t really blame her for thinking it was my fault.
I went out to the shed to see what we had that could be turned into a sink plunger – and just as I was about to attempt to fashion something out of a upturned pot and a bicycle pump I noticed the drain pipe. Just as well really because I think it was never going to work.
