Plumbing systems are a crucial part of any building, providing the necessary water supply and drainage. Here are the basics of plumbing systems:

Water supply

The water supply system provides clean, potable water to your home or building. The water supply typically comes from a public water source or a private well.


The pipes are the main component of the plumbing system, carrying water from the water supply to the fixtures in your home or building. Pipes can be made of various materials, including copper, PVC, and PEX.


Valves are used to control the flow of water in the plumbing system. Some common types of valves include ball valves, gate valves, and check valves.


Plumbing fixtures include sinks, toilets, showers, and faucets. These fixtures allow you to use the water provided by the plumbing system.


The drainage system carries wastewater and sewage away from your home or building. The drainage system includes pipes, traps, and vents.

Septic system

In areas without access to a public sewer system, a septic system may be used to treat and dispose of wastewater. A septic system includes a tank, drain field, and various pipes and valves.

Water heater

A water heater is used to heat the water in your home or building. Water heaters can be powered by electricity, gas, or other fuels.

Understanding the basics of plumbing systems can help you identify and troubleshoot common plumbing issues. However, it's important to remember that plumbing work can be complex and should be performed by a licensed plumber if you're unsure about what to do.
