Get the structure design plan for your drain waste lines
When it comes to that time when you have to make plumbing repairs and changes around your home. To make your life easier it helps to understand your drain waste vent line system (DWV). The bigger pipe lines in your home make up the drain waste vents, carrying wastewater to a town sewer line or your private sewer treatment facility (septic tank).
In our homes today the drainpipes are made of galvanized pipe, copper, or plastic. Local building codes that regulate the materials used in the drain waste vents system have changed over the decades, so most older homes have a combination of different pipe lines (materials).
An ordinary bathroom basin is a good example of how all these components work together. You probably haven’t spent much time observing the pipes beneath your beautiful basin, till the day comes when repairs and maintenance is needed.
- How the basin works is water runs down the basin drain into a p-trap (called this because of its shape), which fills up with water to restrain any sewer gases and odours from getting into your home through the drainage system. This water gets refreshed whenever someone opens the tap for any reason. A drainage pipe connected to the p-trap goes into a cut out in the wall where it meets the bigger vent pipe line.
- On the other side of the wall, a vent line and drainpipe lead to a soil stack line, which is the control center of the wastewater system and is very important to the whole drain system. Drain pipes take the wastewater to the soil stack, where the wastewater is separated from the gases and the sewer gases are carried up to the roof through vent lines, leading all bad odours away from your home.
- All the taps and water appliances in a home use this same system of drainage pipes, and vents. All the waste lines have a cleanout section whereby you can access with ease, which is a Y-shaped fitting that’s accessible so that you can clean out any serious blockage within the drainage system.
