Clearing a vent pipe requires climbing onto your roof. If you are uncomfortable with heights or have a steep roof pitch, call a licensed plumber.
The vent pipe (part of your DWV—Drain-Waste-Vent system) is a vertical pipe that runs from your plumbing system up through your roof. It doesn’t carry water; instead, it lets air into your drainpipes. This air equalizes pressure so wastewater can flow freely. Without proper venting, water in traps gets sucked dry, and drains drain slowly or not at all.
To avoid a repeat performance, consider installing a or a wire mesh screen over the opening. These allow air and gas to escape while keeping debris and critters out. In freezing climates, an insulated vent stack can help prevent ice buildup.
