Bought a new American Standard Cadet bowl on Fri. Installed it and the
wax seal was did not seat correctly. I could tell because 1) it
leaked after being flushed several times and 2) when we removed the
bowl it was only pressed into the wax in two small areas.The flange is
about 1.25" below the newly refinished floor, and the floor is not
level. So I buys a waxless solution made by Fluidmaster, their 7500#.
Installed it and the bowl. Still have a leak. Checked the seal by
touch from the floor ceiling below. It is sealed around the toilet
horn. Only one spot I cannot reach and am making the assumption that
if the seal is touching the bottom well over the horn on the sides
checked then it probably is sealed where I cannot physically ascertain
the seal. Turned off the cold water for the day today and found that
the leak had subsided or stopped, it had been dripping at the rate of
about 1 drop every 10 - 15 seconds. When I arrived home I found no
noticeable dripping and that the water level in the bowl had gone down
to the point where it would be difficult to drain any more by hand.
The tank which was left full did not empty into the bowl. I am
thinking that the bowl is cracked somewhere and letting water seep
out. Is it logical to make the assumption that if the water in the
bowl goes down and the cold water is turned off then the leak is in
the bowl itself? Or is there something else going on?

(This is my final challenge in the remodel and would like to spend a
little more time on it before calling a plumber.)

Thanks in advance,
Bill
