Another expensive trick from Berkey. Now the seller is excellent, but the product is useless if it is not provided with additional valves and adapters. I got this to work (with difficulty) and got an idea of cleaning it to prolong the life of the filters. The water is mostly contaminated with iron sulfide, which contributes to the formation of iron oxide, which simply clogs the outer layer of the filters. With lots of pipe angles, valves, and the right fittings, this will work for me, but it's useless to me.
