There are several things that would cause this problem. (1) A crack in the bowl tyhat can't be seen,**or** (2) Sometimes a bubble will occur in the casting that causes a hole that allows water to leak back down into the closet bend and out into the sewer. Instead of junking the bowl the manufacture will float a porcelain patch over the hole. Sometimes this patch comes loose and the bowl loses water. A blocked vent could cause a lowering of the water level but this almost never happens. You would hear a gurgle in fixtures with lesser traps first. Regards, Tom

Thanks Tom, I can hear a burble sound after water going through the bathroom sink too. But this is only happening in the last two days. Where is the vent located and what is the fix for path problem.
