Both my bathroom washbasins keep getting a black, slimey build-up in the waste pipes. It looks a bit like a blackcurrant jelly - before you mix it with hot water! It doesn't smell. It may be algae. My dishwasher input-matrix also got blocked earlier this year. We have a water softener and I keep it fairly well topped up with salt. What to do? Should I clean my water softener? If so, what with? Its 8 years old, plumbing is the same age (new build). Mr Muscle drain unblocker worked, this time. Any ideas? Thanks Geoff SaffronWalden (hard water)
