I can only agree with the execution of John Oe! After long-term experiments with commercially befindlichen- supposedly oh-so-effective, and expensive! - Pipe blockage solvers has my drainpipe zugekleistert increasingly in the kitchen and eventually stopped working even the dishwasher. Apparently the Aqua-Stop function had recognized that no water can run off and therefore not at first let in water in the machine. I was about to buy a new, because there I really could not see any connection with the pipe blockage. Previously I had ordered a pipe cleaner company with a pipe blockage and paid a lot of money for it. The solution came by referring an acquaintance that sulfuric acid helps that you have to buy at the pharmacy and the pharmacist always make a fuss if you want to buy something. Then I looked just check out Amazon, found the offer of Otto Fischer GmbH and ordered. After initial anxiety because of the many safety instructions I hesitated a bit, but it finally tried it. Lo and behold, it worked without any problems at the first time, my drain is again knotless and even the dishwasher has entered into service again. Really great! In my circle that some want to do so without having to hire a company.
