Does A Kitchen Sink Need A Vent?

Yes, a kitchen sink does need a vent, but this is often tied into your whole home drainage system and is typically connected to the main sewage line rather than the sink's direct drain system. If your sink is fairly far away from the waste vent, you may need to look at under the sink options. A professional plumber will be able to help you decide where to place a vent in your system.

What Does a Vent Do?

In plumbing, a vent relieves the pressure built up by the draining water. It allows air to enter and escape the drainage system, preventing buildup and helping the traps in your plumbing to expel the sewage gasses outdoors. Without proper venting in your drainage system, your water will drain slowly, and drains will release strong sewage odors.
