From Pathfinder Wiki
Drainage systems generally work by gravity. The waste pipes are installed so that they drop at least a quarter of an inch per foot (or 2 cm per meter). Any drains below a building's waste exit point must be drained into a tank equipped with an effluent pump to move the waste out of the building.
Hot and Cold Water systems
Fresh water enters a house at the main, going through a master shutoff valve. The pipe then hits a tee, with one side feeding the water heater and the other side feeding the cold water taps, toilets, dishwashers, etc. A water heater has two lines coming to it. One is the cold water supply already mentioned. The other is the heated water outlet which feeds all the hot water taps in the house.
