We received this enquiry from a reader concerning domestic-water testing
Can someone recommend a water testing for a house in the Almunecar area?
A friend is finding that her toilet incoming water turns black and needs to be cleaned every 2-3 days.
Seems to me that the incoming pipes may be old lead ones. Highly likely that her drinking water is also polluted.

Big clue. 5 or 8lt bottles tend to be used in homes. After all , do you want to drink parasites you cannot see. I filter mine twice. Only issue is washing up. So a dash of bleach kills all know Germans. Sic. !!
