Key Components of a New House Plumbing System

Drain-Waste-Vent (DWV) System
The DWV system is designed to remove waste and wastewater from the house. This system includes drainpipes, traps, and vent pipes that allow air to enter the system and prevent sewer gases from entering the home. Proper installation of the DWV system is essential for sanitary living conditions.
Plumbing Fixtures and Appliances
Plumbing fixtures and appliances include sinks, toilets, and dishwashers that use water and require connections to the plumbing system. These components must be installed correctly to function properly and avoid leaks or water damage.

Setting Up the DWV System
The DWV system installation involves setting up drainpipes, traps, and vents. This system requires careful planning to ensure waste is removed efficiently and gases are vented safely.
