A toilet's drain must be run at 1/4 per foot minimum grade when horizontal. A toilet cannot be installed upstream of any wet vented fixture. The maximum vertical fall of the drain is 1 meter(39 inches) and the maximum horizontal run is 3 meters before it connects to a vent. All downstream drainage after the connection of a third toilet on the same horizontal pipe must be 4 diameter or larger.
Distance between finished wall and center of a floor drain or rough â in might be 10â, 12â or 14â depending on toilet type. But most residential floor mount toilets require one foot (305 mm) drain placement from the back wall. Minimum 15â space should be left between the center of a drain and finished side wall.
