Its not syphaning. The toilet is burping air is being pushed out of sewer line up through the "S" trap, just sitting not in use. When you flush the air burps then backs up slowly will drain.
Pulled toilet "S" trap clear, even ran a small camera inside to make certain.
Out side ran 1" cable through main drain. Ran 1/2" cable through 4" W/C Elbow 28 feet, ran cables up through vent to roof (Verified through roof by person on roof). It clears the toilet up for 3 days then the burps return.
Anyone have an idea on the cause, and even more helpful a cure? (Beside hold my breath, or a spoon of sugar)
