Hey Boys,
I'm having trouble with an Am Stan elongated bowl WC. It has one of those new flappers with the styrofoam floaty thingy on the flapper. There are two problems. One is that the flapper prematurely closes, and the other is that it doesn't flush very well.
It does flush with the aid of extra water dumped in. I've also reamed all the holes under the rim, and I've reamed out the siphon jet. I've even dumped hydrochloric acid down the refill tube to clear things out internally.
I didn't get the model number, but it's the one that looks like an old-fashioned style.
Got any ideas?
Mikey
