Replaced a previous American Standard toilet that never really did flush correctly. Almost didn't get another American Standard because it was so bad. But when at Lowe's this guy picking up a Cadet 3 said he had several and liked them. So got one.
It really did flush well with very little water. Unlike the previous one that used a lot of water and just swirled it around the bowl. Still, the flapper from American Standard is not very good. I shouldn't have to hold the handle down to make sure it flushes fully. So was going to head to the store this morning and buy a korky flapper. But came up with an idea I tried it this morning instead.
Just like mentioned on here, the flapper closes way too fast. So I took the puck shaped float from the previous toliet and cut it in half. Then pushed each half up into the bottom of the OEM flapper cavity. I had it on the chain right above the flapper, but that didn't work and see someone tried that as well. Well, this new location works perfect. The float is now under the flapper in the cavity. And when flush it keeps the flapper up longer so get a full flush now.
One half the float might work well also, but haven't tried that.
If I haven't made myself clear enough can take it out and post a picture.
