3 Signs of a Clogged Plumbing Vent


Plumbing vents are the upright pipes running inside the walls and out of your home’s roof. They permit air to enter the drainage system by maintaining an even pressure to allow wastewater to flow from your home fast and efficiently. Excessive corrosion, an accumulation of leaves, or bird nests on top can cause the vents to become clogged.

Look For These Red Flags

As water flows down a drain, air is required to balance the pressure in the drain line. The top three signs your plumbing vent is clogged are:

Strong Sewer Gas Odor

All plumbing drains have a trap in a place where water remains to block sewer gases from reversing into your house. When drain pressure is too high, the water flows out. The result is leaving nothing to prevent the gaseous odors from penetrating your home.

Sputtering, Gurgling Toilets

When airflow is inadequate in a vent because of size or blockage, the plumbing pressure will be greater than the air in the bathroom. When you flush the toilet, the water fights the higher pressure, causing it to sputter and gurgle.

Slow Drain

Elevated drainpipe pressure prevents water from draining off at an average rate. When tubs and sinks drain slowly, it may be an indication of an undersized or blocked vent. There could also be a clog in the pipe that services the water flow.

A blocked or clogged plumbing vent is not an easy fix, because it usually involves breaking walls open to examine the entire drainage system.
