To begin at the top of the pay scale with the highest ranking law enforcement officer in a city police department other than the commissioner, the police chief is paid anywhere from $90,000 to $114,000 in base salary.
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.
The toilet is vented through the sink drain. The toilet drain should be 3â³, the sink drain is 1.5â³, the shared sink drain/toilet vent area should be 2â³, and the vent going up should be 1.5â³. Also note that where the 2â³ drain connects to the 3â³ at the bottom the fitting should be a y instead of a tee as shown.
