Water Filtration System Repair near Delwood Rd. I was called to a residential property where the homeowner reported that their water filtration system was producing a metallic taste in their drinking water. After inspecting the system, I found that the iron filter was not functioning properly and needed to be adjusted. I also found that the carbon filter was expired and needed to be replaced. After adjusting the iron filter and replacing the carbon filter, I tested the system to ensure that it was producing clean and tasty drinking water. The homeowner was satisfied with my work.
