We need help with our water heater that was discharging water daily through the pressure relief valve. Fast Water Heater diagnose our problem as a malfunctioning external expansion tank. To reduce water heating costs we chose to have a tankless/hybrid gas water heater installed. In 10 da. the flow valve failed. We all worked together. WE were assured we have a dependable product. Repairs were made a fast as possible and we are satisfied with our decision to work with Fast Water Heater. Lloyd Piper
