Water Filtration System Repair near Mitchell Dr. A homeowner contacted me regarding an odd taste in their drinking water from their under-sink water filter. After inspection, I found that the carbon filter was expired and needed replacement. Additionally, the tubing connection was loose and needed to be tightened. After replacing the filter and tightening the connection, I tested the system to ensure it was producing clean and tasty drinking water. The homeowner was satisfied with my work and glad to have a better functioning under-sink water filtration system.
