Drain, Waste & Vent Systems
Every time you take a shower, wash the dishes, or flush the toilet, you’re relying on your building’s Drain, Waste & Vent (DWV) system. This piping is responsible for removing sewage and greywater from your residence and directing it safely into the municipal sewer system.

HAWAI‘I'S Choice FOR CAPITAL IMPROVEMENT PROJECTS

Key Details
System Components
The "drain" component transports water and waste from sinks, showers, and appliances to the sewer line. The "waste" section handles solid and liquid waste materials such as toilet discharge, ensuring a sanitary environment. The "vent" system releases harmful gases and maintains proper airflow within the plumbing, preventing pressure imbalances that can cause backups or unpleasant odors.
Corrosion, Cracks and Buildup
Constant exposure to moisture, chemicals, and gases cause pipes to rust and weaken over time, leading to eventual failure. Debris and buildup can obstruct flow, resulting in backups and clogs. Cracks can cause leaks, leading to water damage, waste seepage, and foul odors.
