How does a DWV system work in a home?
While each home’s DWV system will have a slightly different layout, most DWV systems follow a basic pattern. Usually, there is one vertical pipe (often called a “stack”) that runs from roof to basement, and connected to the main stack are multiple horizontal pipes at each level of the home.
What does DWV stand for in plumbing system?
What is the DWV System? DWV stands for Drain-Waste-Vent. Your home’s Drain-Waste-Vent plumbing system is the collection of pipes that rid your home of sewage and water waste from toilets, bathtubs/showers, sinks and appliances like dishwashers and washing machines. There are two parts to the DWV plumbing system: drain-waste pipes and vent pipes.
How does a DWV system maintain neutral air pressure?
DWV systems maintain neutral air pressure in the drains, allowing free flow of water and sewage down drains and through waste pipes by gravity. It is critical that a sufficient downward slope be maintained throughout, to keep liquids and entrained solids flowing freely towards the main drain from the building.

What’s the difference between DWV and standard PVC?
The result is a less expensive product with a few specialized parts that are particularly useful for drain and vent uses. A few parts that are typically used for DWV applications are p-traps, drains, and cleanouts. Another difference between DWV and standard PVC parts is the end types.
Are there any problems with cast iron DWV pipes?
Unfortunately, as buildings age, the corrosion of cast iron DWV piping can become a severe problem. Depending on the external environmental conditions and the corrosiveness of the liquid waste and gasses within the pipes, major blockages and even complete structural collapse are not uncommon.
