Frequently Asked Questions

Q. "How can I find the model number of my Gerber toilet?"
A. Look inside your tank. Always exercise caution when removing the tank lid, as it is fragile and can be easily broken if stepped on or dropped. 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 below left). For pressure assist tanks, the number will be closer to the top of the tank (example below right).
