How to find your Gerber toilet model number
How to find your Gerber toilet model number:
  1. Carefully remove the tank lid and place gently in a safe spot.
  2. Look inside the tank starting with the back wall - for non-pressure assist models, the model number will be painted just above the waterline (example above left). For pressure assist tanks, the number will be closer to the top of the tank (example above right).
Please note: Due to safety concerns with pressure assist toilets, we choose not to offer parts for these models.
