I've got three good American Standard toilets in my house - the kind that use a lot of water (thankfully).

They've all been retrofitted with the cheap fluidmaster toilet repair kits. The problem is that they never seem to last that long. They run for like 10-20 seconds, usually in the middle of the night and then stop. Leaking somewhere obviously, but I've replaced all parts inside the tank - including the flapper.

I've had to replace them all regularly - like once every three years. When I was a kid, in Illinois, I can't recall my dad ever replacing a toilet flush mechanism. We had those old brass or bronze? mechanisms with the big plastic ball float.

Is there a premium, old-fashioned kit for American Standard that I can use so I'm not buying and changing these Fluidmaster kits so often?

Thanks.
