  David ParkerAug 3, 2025
  If adjusting the temperature knob to full hot on your Moen Plumbing Product results in cold water, and adjusting it to full cold gives hot water, it indicates that the hot and cold supply lines to the valve are reversed. To correct this, disconnect the supply lines and reverse the connections, ensuring that the hot water supply line is connected to the “Hot” connection and the cold water supply line is connected to the “Cold” connection.
