Residential plumbing is a system that provides fresh water to a home and removes wastewater. It consists of two main systems: the water supply system and the drain-water vent system (DWV) .
Water Supply System:
The water supply system brings fresh water into the home. The water in these pipes can come from either city water or wells . City water enters the house through a main pipe that is usually parallel to the street. If there is a problem with the connection to the main pipe, it is recommended to call a professional, as damage to the main pipe can result in civil lawsuits and fines .
Drain-Water Vent System (DWV):
The drain-water vent system is responsible for removing wastewater from the home. It consists of a network of pipes that carry wastewater from sinks, toilets, showers, and other fixtures to the main sewer line or septic system. The vent pipes allow air to enter the system, preventing suction and allowing wastewater to flow smoothly .
Plumbing Basics:
Plumbing follows the basic laws of nature, including gravity, pressure, and water seeking its own level .
The water that enters a home is under pressure, allowing it to travel upstairs, around corners, and wherever it is needed .
The main water shut-off valve, typically located close to the water meter, is vital in a plumbing emergency. Closing this valve quickly can prevent flooding in the event of a burst pipe .
It’s important to have a basic understanding of residential plumbing to make informed decisions and troubleshoot common issues. However, for complex plumbing tasks, it is recommended to hire a professional plumber.
