I have two sump pits/pumps and get a lot of water in each. I also get a fair amount of "sludge" in each. It smells like sulfer, has an orange or rusty tint and slowly clogs my 1 1/2 inch discharge pipe that is connected to the pumps, every couple of years. I'm looking for a way to cut down or eliminate the sludge. I've had an estimate for the Watergaurd system for $15K, and they claim it will elminate the sludge problem. Before I pay that kind of money, I wanted to get an independent opinion of that system. Any advice?
