I have an American "Standard" K54 foilet from 1954. Perhaps 18 years ago
I installed a Fluidmaster Flusher Fixer kit. Worked fine, for a long time.

Still works fine, but it needs a replacement flapper. I search everywhere,
can't find one. Call Fluidmaster, wait 20+ min., nobody home.

Fluidmaster has a "New, Improved" Flusher Fixer kit. Totally unlike the
old. I go to Homey-Flogging-Depot, that's all they got. Damned thang
looks like a Rube Goldberg Frankenstein.

Fluidmaster doesn't support replacement parts for it's products. Howcum
we don't have a reliable and dependable toilet fixtures company??



*Go back to where you purchased the kit 18 years ago. They may have the
parts. Home Depot does not sell things that are found at other
distributors.
