The main water line is connected to the municipal water source or a private well through the water supply line, which brings potable water into the home.

Hot and cold water lines distribute hot and cold water to different areas of the house, with hot water lines typically connecting to a water heater or boiler.

Fixtures like faucets, sinks, toilets, showers, and bathtubs allow you to use water for various tasks and activities, while the drainage system carries wastewater and sewage away from the house through pipes, vent pipes, and traps.

Traps are curved sections of pipes that retain a small amount of water to prevent sewer gases and odors from backing up into the house.

Most water fixtures in your home use both hot and cold water. Two separate water lines run to those fixtures, one hot and one cold.

Your dishwasher has just a hot line, and your toilet has a single cold line. Some appliances only need one or the other.

After the main water line enters your house, it forks into two separate hot and cold lines.

The cold line forks into even more separate lines, which all get sent to various water fixtures around your home to supply the cold water to those fixtures.

The hot water line routes to a water heater before it separates into lines for the individual fixtures.

Shut-off valves are essential for controlling the flow of water within your plumbing system. They allow you to isolate specific areas or fixtures for maintenance, repairs, or emergencies without disrupting the entire water supply.

The main shut-off valve, usually located near the water meter, controls the entire water supply to your house. Turning it off stops the flow of water to your entire plumbing system.

Knowing where the main shut-off valve is located is crucial in an emergency, so make sure everyone in the household knows its location.

The main pipe that connects your home to the municipal water source or a private well is called the Water Supply Line. It brings potable water into your home.

Your home's plumbing system has several types of pipes, including copper and galvanized steel, which are commonly used for the main water line.

Hot and cold water lines distribute hot and cold water to different areas of your home. Hot water lines typically connect to a water heater or boiler.

The water supply line forks into two separate hot and cold lines after it enters your house. The cold line then forks into even more separate lines, which get sent to various water fixtures around your home to supply the cold water to those fixtures.

Traps are curved sections of pipes located beneath sinks, showers, and toilets. They retain a small amount of water to prevent sewer gases and odors from backing up into your home.

The main sewer line transports wastewater and sewage from your home to the municipal sewer system or a septic tank.

Copper piping has been a staple in the plumbing industry for decades, with a lifespan of over 50 years. It's commonly used for sinks, showers, tubs, and other fixtures due to its corrosion-resistant properties and ability to handle high water pressure.

Copper pipes are available in different types, including Type M, Type L, and Type K, each with varying wall thicknesses for different applications.

PVC pipes, on the other hand, are widely used for drainage and waste systems due to their lightweight and corrosion-resistant properties. They're also easy to work with and come in different sizes.

PEX pipes are a type of flexible pipe made of cross-linked polyethylene, making it strong enough to handle water pressure while also being easy to install.
