Hi everyone. An American Standard toilet in our powder room does not flush
with great force. Sometimes remnants remain and require an extra flush.
The other 2 toilets in our house are exactly the same, but flush with
greater force. Is there anyway to increase the force with which a toilet
flushes?
Can I buy a different flush valve?

I have tried increasing the water level in the tank, no good. I have
cleaned out the little holes inside the edge of the bowl, no good.

Thanks for any help/suggestions.
