Over time, the iron content present in the water supply will gradually accumulate and adhere to the inner walls of the pipes. As this buildup of iron oxide (rust) persists, it will cause the diameter of the pipes to narrow down progressively. If left unchecked, the restricted flow area within the pipes due to this iron buildup can become so severe that it creates a bottleneck effect. This substantially diminishes the rate at which water can pass through the pipes, resulting in a significant reduction of flow and potentially leading to complete blockages in severe cases. Consequently, the decrease in water flow caused by the occluded and constricted pipes can impair the overall functionality and efficiency of the plumbing system, necessitating maintenance or replacement of the affected pipe sections to restore proper water flow. An Iron filter from Mountain Water Systems solved this problem!
