Drain pipes are vented outdoors to equalize negative and positive pressures inside them, allowing wastewater to move freely. Plumbing vents also prevent sewer odors from entering your home. Knowing when they have problems can be mystifying to homeowners. Here are the top symptoms of poorly-vented drain lines.
If there’s a pungent odor in your home, sewer gas may have infiltrated your home. Blocked plumbing vents may create negative air pressure within your pipes. This sucks water out of the P-traps, allowing an influx of sewer gas.
If your drain lines are working properly, they shouldn’t be any strange sounds coming from them. If you hear burps and gurgling sounds inside them, that’s a sign of pressure not escaping through the vent stacks as it’s supposed to.
Are your drains slow despite your best efforts to try and open them? That could be due to poorly-vented drain lines. Blockage in the vent pipes can create pressure imbalance in the drains, slowing drain action.
Poor Toilet Flush
Bubbling Toilet Bowl
If you see bubbles in your toilet bowl when there’s water draining elsewhere, for example from a nearby washing machine, a blocked vent is to blame. The blockage causes an excess buildup of pressure inside your pipes that forces air up through your toilet bowl.
If you notice one or more of these signs, it’s best to call a professional who’ll use specialized plumbing tools to diagnose your drain and vent problems.
