The water supply system is responsible for delivering clean water to various fixtures throughout the home. It includes the following components: - Water meters: Measure the amount of water consumed. - Main water shut-off valve: Allows homeowners to stop the water supply in case of emergencies. - Pressure regulators: Control the pressure of the water supply. - Piping: Carries water from the municipal supply or private well to the home. - Water heater: Warms water for household use. - Branch lines: Distribute water to individual fixtures. - Fixtures: Receptacles for water use, such as faucets, showers, and toilets.

The drainage, waste, and vent (DWV) system removes wastewater from the home. It consists of the following elements: - Drainage pipes: Remove wastewater from fixtures. - Traps: Prevent sewer gases from entering the home. - Vent pipes: Allow air to enter the system, maintaining proper pressure. - Cleanouts: Access points for cleaning and maintaining the DWV system. - Stack: A central vertical pipe that connects all fixtures' drains.

Plumbing systems require durable, long-lasting materials that can withstand water pressure and resist corrosion. Common materials include: - Copper: - PEX (cross-linked polyethylene) - PVC (polyvinyl chloride) - CPVC (chlorinated polyvinyl chloride) - ABS (acrylonitrile butadiene styrene) Professional installation is crucial for a leak-free, efficient plumbing system. Proper slope, secure connections, and regular inspections during construction ensure long-term functionality and safety.

Routine maintenance prevents leaks, reduces water waste, and extends the lifespan of plumbing systems. Homeowners should: - Inspect the system regularly. - Address leaks and issues promptly. - Clean fixtures and drains regularly. - Clear clogs properly. - Winterize exterior faucets. Upgrades may be necessary to improve efficiency, accommodate changing needs, or address wear and tear. Examples include water-saving fixtures, tankless water heaters, and repiping.
