The folks at the hardware store don’t think these products work, but they have helped us. We have an older septic system in the country which occasionally has standing water over the drain field. Obviously, that means it isn’t working. We feel that dumping septic treatment in the toilet every few months has helped the standing water, and we’ve never had to dig it all up for repair. Although I’m sure we will have repairs at some time in the future, we’ll continue to use this stuff to postpone the inevitable as long as possible.
