I recently purchased this Toto toilet CST743S-01. The darn thing is giving me fits installing the tank. I can't get the tank to touch all three point on the bowl. It keeps hitting the back point and is maybe 1/4" from the front 2 points. I called their tech support. One guy said that is ok. Another said its not ok and try to soak the gasket in hot water and then have somebody push down on the tank while tightening.
I'm afraid in its current state if I crank down on it anymore the tank will break. This is my 3rd Toto toilet I've installed in the house. The other 2 didn't give me this many problems. I was hoping some others might have some tips for me. Any advice would be greatly appreciated!
