I had the same problem at my house and my Dad's and the next door neighbors. The older American Standards we tried to tolerate were terrible.

It was explained to me that TOTO had the patent for a low water use toilet that would actually flush, but most other manufacturers are copying now. I suppose the patent ran out or something.

I have installed several Glacier Bay and they all work fantastic. They are the cheap chinese ones you get at Home Depot for $100 or so. I imagine most new toilets have copied the TOTO design and will work much better than what you have. Look for the big opening for the flush at the bottom of the tank.

We all know advertising works, we just don’t think it works on US!
