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
Got any ideas?
I'm not up on my A.S. repair details, but assuming that the flapper is a
standard flapper with the cork float try lowering the float as low to the
flapper as you can get it. This should get you little more water. You can
also try raising the water level above normal height. I've even glued a 3/4"
PVC coupling and a short piece of pipe to raise the water level on some A.S.
and Eljer toilets that just wouldn't flush.
I've already done both those suggestions. As a matter of fact, they
were adjusted that way when I arrived (telling me it's been a continuing
The thing is this, that if I dump in just about half a gallon of
water during the flush cycle, it flushes fine. I don't think the
problem is the amount of water, but the speed that the water has as it
enters the bowl. I've reamed all the holes, and bathed the siphon jet
with acid. Is there anything else to try?
Assuming that there's no vent or drain stoppage issues and you are giving it
all the water you can. Even more than it was designed for. And you've
cleared the bowl jets. The only other possibility is some sort of
obstruction beyond the flapper, either in the flush valve or the upper
portion of the bowl.
That said, it only takes a couple of hours extra labor for your customer to
just buy a whole new toilet.
Another thought....I'd also confirm that the toilet hasn't been repaired by
someone else that may have changed out the tank to an incorrect model.
