Water Filtration System Repair near Shanley St. I was called to a home where the client reported that their water filtration system was not removing enough sediment from their water supply. After inspecting the system, I found that the sediment filter was not rated for the home's water supply and needed to be upgraded. I also found that the backwash valve was not functioning properly and needed to be replaced. After upgrading the sediment filter and replacing the backwash valve, I tested the system to ensure it was removing enough sediment.
