DWV System. Drain-Waste-Vent

Your home’s plumbing system is critical to your family’s comfort and hygiene, and it’s important to keep it all in good working condition. Anta Plumbing offers a range of plumbing and sewer maintenance service to residential, commercial or industrial property owners. Contact us today to perform a video sewer inspection to show you exactly how well your drains are functioning.

All About Your Sewer System

When you turn the faucet off and the water flows down the drain in your sink or you flush the toilet, the waste needs to go somewhere and the pipes that carry these liquids and solids away from you home are called the drain, waste or drain waste vent (DWV) system.

To make sure waste gets to where it’s supposed to go, this system is equipped with a range of pipes with large diameters. The system has three important components. As the name implies, the drain lines carry the water away from the showers, tubs and sinks. The waste line takes care of what needs to leave your home from the toilets and the sewer gases are vented through the aptly named vent lines. These lines also provide air pressure so waste water can flow freely.

Gravity Works Here

These systems are engineered to take advantage of gravity in that both the waste and drain lines slope away from the fixtures to sewer lines or septic systems. The correct diameter is also important in preventing blocked sewers. Toilets generally get the largest soil stacks at 10.2 cms, while showers usually have 5.1 cms pipe and other fixtures that carry water like bathtubs, sinks and laundry tubs, have pipes with a 3.2 to 5.1cm diameter.

Waste water pipes carry the waste water to vertical stacks whereby vents carry gases to upper portions where they escape through the roof. Another critical aspect of your plumbing and sewer system is what’s called the trap. This U-shaped section of pipe under fixtures serves an important role in that the trap holds water even when the fixture is empty. This water forms a seal that keeps any sewer gasses that are leaving from entering the house.

Homeowners can make sure everything is running smoothly through the cleanouts on the stacks and main drains. These elements offer access for unclogging the drain system when needed.

Of course water and waste leaving your home is only part of what you need to concern yourself with. Relying on the right system to get fresh clean water into your home in just as important and the main supply line is controlled by a main shutoff valve in the basement, and an underground curb valve outside your home. Once the water make its way in, it goes past the water meter that tells your municipality how much you use and then gets divided into hot and cold lines that lead to the corresponding fixtures inside your home.
