We recently installed an Iron Filter and Water Softener for this new customer in Marshall. That corrected the iron staining and water hardness. But the customer noticed that the sediment filter was clogging up with black sand-like particles rather quickly. They were changing the filter every two weeks or sooner. So we recommended and installed a Settling Tank to solve this issue. They reported back to us that the sediment buildup was not an issue any longer. Another happy customer!
