Overview
A homeowner repairing a toilet tank would use this Gerber flapper, which the listing names without further detail. It is filed under toilet flappers, the tank part that closes the flush valve opening.
Buying by an exact model number is the reason to consider it when the old part carries the same number. The limitation is the lack of data: no size, material, float or chain information is shown.
Who it's for
A person replacing a Gerber flapper with a matching model number can use the number to find the right part. Anyone starting from the toilet model or the valve size should confirm fit elsewhere first.
Pros and cons
- Exact model number given
- Gerber brand part
- Size not listed
- No material details
- No fit information
Performance notes
A flapper seals the tank outlet and lifts during a flush, so fit to the flush valve opening decides whether it leaks. The listing gives no size to check against, so the old part is the best reference.
