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.

Frequently Asked Questions

Q. "What are the most commonly replaced toilet parts?"
A.This depends on several factors; each time you use your toilet the trip lever, flapper, and fill valve are operated. You will find, however, that the flapper and fill valve are the parts most exposed to water and will be the first ones to wear out in most cases.

Q. "How long 'should' the parts inside of my toilet last?"
A. That depends on a number of variables and which parts. Water quality is one of the major factors. If your water source is heavily chlorinated then many parts won't last long. Or if you have a lot of sand or grit or have a low pH or "aggressive" water source then parts simply won't last as long as the 'average' length of time. Also the quality of the parts matters. The replaceable parts such as flappers and washers/seals generally will last at least 4 to 5 years on "average." If you use a bowl cleaner some flappers won't even last one year. If your flapper has black "goo" on it then it is either due to age or quality of your water and if it feels soft then it's best to change it.
