A Faulty Sewage System May Be to Blame For Toilet Bubbles

Understand why a toilet is bubbling and making strange noises during a storm


Are you confused about why your toilet water is bubbling when it rains outside? Are you wondering how to navigate such a situation? If yes, then this post is for you. The professional storm damage team at SERVPRO of Winter Haven has the answers for you!

Common causes for a toilet to bubble
When a wet venting system (plumbing vents) is in operation, and several drains flow down into one pipeline, toilets will flush and head to a septic system. However, when there is a blockage in a pipe, sewage water can return to your shower, toilet, and sink.

A gurgling toilet means that negative air pressure (suction) is built up, forming a kind of airlock in the drain line. Air flows freely via the lines in a well-functioning sewer system, avoiding negative air pressure, so waste can perfectly flow down and out. Gurgling in the line suggests unusual suction formation. Eventually, the negative air pressure will be released, pushing air back through the drainage pipe and into your toilet bowl. You will hear a gurgling noise when this occurs, and possibly the water in the bowl may bubble.

What to do when your toilet is bubbling during a storm


The first thing you should do is check the area near the septic system for damp spots or standing water. Whether you notice any standing water or not, you should ask your neighbors if they face a similar issue. You will know if the problem is only occurring in your home or the entire neighborhood by asking your neighbors. If you are the only one with the issue, rainwater may be directly pouring into your sewer system.

Another possibility is a sewage blockage in your sewer line, causing your toilet to bubble. Toilet bubbles and gurgling are usually caused by excessive water trying to go down a moderately restricted pipeline. Rainwater could have gotten into your sewer system through a cracked pipe or a sump pump in the basement.

Toilet bubbles may lead to water damage


A bubbling toilet can cause various problems to your home in the long run. Such unnoticed small issues can result in plumbing problems in the future and even toilet water gushing out of the toilet and spewing all over your house. If you find yourself with a bubbling toilet during a storm, you need to contact SERVPRO of Winter Haven at 863-551-5004 for professional help.

As mentioned, water from a bubbling toilet can eventually cause excessive water damage. Your sewage system is not designed to handle rainwater, and if this occurs, it will ultimately cause a backup in your home. Water damage will cause damage to the walls, ceilings, electrical systems, and floors. Since the water damage will be caused by contaminated water, all contaminated items will have to be removed, and an antimicrobial agent will have to be applied.
