Plumbing is a system that supplies and drains water in your home. The plumbing system is composed of two subsystems: one brings freshwater in, and the other takes wastewater out . The supply and drainage systems must always be two distinct subsystems, with no overlapping. At the fixtures (bridges between the two systems), the air admitted by the vent stack and vent pipes keeps the traps sealed and prevents sewer gases from backing up through the drains.
The water that comes into your home is under pressure. It enters your home under enough pressure to allow it to travel upstairs, around corners or wherever else it’s needed. As water comes into your home, it passes through a meter that registers the amount you use. The main water shut-off, or stop, valve is typically located close to the meter. In a plumbing emergency, it’s vital that you quickly close the main shutoff valve. Otherwise, when a pipe bursts, it can flood your house in no time
The drainage system does not depend on pressure, as the supply system does. Instead, waste matter leaves your house because the drainage pipes all pitch, or angle, downward towards the sewer. Gravity pulls the waste along. The sewer line continues this downward flow to a sewage treatment facility or a septic tank. While the system sounds simple, there’s more to it, including vents, traps and clean outs .
I hope this information helps you understand the basics of plumbing. Let me know if you have any other questions!
