I went to a property just over a week ago as I was called to a blocked kitchen sink. After initially checking the waste disposal unit and found it was clear, I took out my trusty ‘man-vac’ (that’s a hoover that sucks up dry and wet waste) and cleared the blockage that had accumulated in the monstrosity pictured below:
If your waste falls away from your discharge pipe and not towards it, don’t scratch your head and wonder why your sink keeps backing up!
In the end it was a hoover full of ground coffee that took up residence in this … plumbing from hell!!
