Your house has pipes that go through the roof, called vent stacks. They let air in so water can drain smoothly. If leaves, a bird’s nest, or a tennis ball (yes, really) blocks that vent, the system gets pressurized.
That pressure can suck the water right out of your P-traps. Then, bam—sewer smell. It’s often accompanied by a gurgling sound when you flush a nearby toilet or run a sink.
Cleaning a roof vent is a bit more adventurous, but it’s a fun little DIY project on a sunny Saturday. Just be careful up there!
