Puzzled - Water Supply
For years ( yes literally YEARS) my water supply has left black streaks in the toilet after 3 or 4 flushes & sticky black deposits in the tap filters.
I have complained about this to Severn Trent a number of times with no joy - "Oh we have flushed the mains, it must be bio-film".
For the past 2 weeks it hasn't happened.
I'm puzzled - can anyone cast any light?
