Drain, Waste & Vent
Though it isn’t one of the most glamorous parts of a house, the drain-waste-vent system is one of the most necessary. The pipes that make up this system are designed to carry away waste water and sewage from sinks, toilets, and water-using appliances and to ventilate sewage gasses. The pipes are usually out of mind because they’re out of site in the walls, beneath the floor, and in the attic. But when the system ceases to do its job properly, it becomes painfully evident.

This section will help you understand how they work and what to do when they don’t.
