Water Supply • Water is provided at a constant pressure through a public water system • Water is provided by a pump for systems using a driven well • Pipe diameter regulates pressure
Components • Main Line • Water meter (public water) • Hot water heater (gas, or electric) • Supply Lines (hot, cold) • Drainage, waste, and vents • Sinks, toilets, tubs, etc.
How it Exits • DWV system (Drainage, Waste, Vent) • Drainage and waste controlled by gravity • Larger pipe diameter • Sent to sewer or septic
