Hello,
We have had serious problems the last while with a bacterial growth in our rising main (service pipe) that feeds water into our house. There are often black particles in the water, these are organic, and not sediment or plastic or anything. They seem to be the root of the problem. Does anyone know how I might be able to perhaps air scour and disinfect this pipe run? It would be about 25 feet long. We are on mains water by the way.
