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.
For example on a 1 1/2â³ sink drain the vent can not be located more than 5ft away from the trap and the pipe between the trap and the vent can not have bends in excess of 135 degrees. The rules for siphonic fixtures such as a toilet differ. You can have the vent 10ft away and have 225 degrees before the vent.
