Signs of a Blocked Plumbing Vent

A plumbing vent is responsible for regulating the air pressure in the plumbing system. Also known as a vent stack, they’re usually found on roofs. If drain pipes flush water and waste out of your house, plumbing vents release gas and odors. Fresh air also passes through them, allowing the water (and waste) to flow smoothly into the sewer system. A blockage will require the help of a plumber in San Francisco. Here are signs that point to a clogged plumbing vent.

Noisy Drain

When a blockage restricts air flow in the pipe, the air will try to escape through the drainage. This produces gurgling and rattling noises whenever you let water out of your bathtub, shower, or sink. It can also cause the water to bubble up and down the drain.

Slow Drain

If you notice that draining water takes longer than usual, then it may indicate that the vent is blocked. Check if this slow rate is consistent and located in one part of your house (not just one fixture). If it is, then there’s a high chance that there’s a problem with the vent. But if this problem is present throughout your property, and on multiple floors, then the issue could lie in the entire plumbing system.In that case, you’re definitely going to have to call a team of plumbers.

Flushing Problem

Toilets rely on air pressure to effectively flush out waste. If a plumbing vent is clogged, the right amount of air pressure can’t be produced. This leaves the water and waste stuck in the toilet bowl. You might also notice that the level of water in the bowl is consistently low. The same concept applies to water coming in.

Unpleasant Odor

When the air and gas in your bathroom can’t pass through the vent pipes, they escape through the drain. This means that the drainage pipes in your tubs, showers, and sinks may emit a strong, unpleasant odor. What you’re smelling is raw sewage. In some cases, you might detect the smell coming from your toilet as well.

If you notice any of these issues in your bathroom, don’t think twice about calling a professional plumber. San Francisco residents can get in touch with many companies that offer plumbing services.
