There are several ways to repair the problem of toilet bubbles when the tub drains. The first way to fix the problem is to unclog the drain using a snake or auger. If the obstruction cannot be removed, a professional plumber should be called. Most modern bathrooms are equipped with a DWV system, or drain waste vent, to remove the waste from the building. With this system, the focus is not only on the waste but also on the venting system.

Symptoms

If your toilet is gurgling and bubbles when you use it, you may have a blockage that needs to be repaired. Sometimes, this issue can be resolved without contacting a plumber. Other times, the blockage is a symptom of a bigger issue.

Toilet bubbles are a common plumbing problem, but it can also be an indication of a larger problem. It may be a simple problem that you can easily fix on your own or a more complicated issue that you need to call a plumbing professional to fix. Here are some common plumbing problems that can cause bubbles in your toilet.

The problem can also occur if you have a clogged main drainpipe. When this happens, the waste will not be able to flow into the sewer lines, accumulating instead. At first, only the toilet drains, and the adjacent fixtures will bubble, but as the waste accumulates in the pipe, sewage will start to flow out. When this happens, the clogged pipe may be partially blocked, but bubbles will persist until there is no more space left.

Causes of toilet bubbles when tub drains

Toilet bubbles occur when air is sucked out of the drain pipe as water drains through it. This causes the water in the bathtub to back up, which can lead to an overflow in the toilet. If you notice this problem, you should take action to stop the bubbles before it gets any worse.

The cause of toilet bubbles is usually a clog in the drain line. This clog can be caused by disinfecting wipes, paper towels, or feces that mix with debris. The debris pushes air backward in the drain line, which causes the water level in the toilet to temporarily rise as you flush. If the drain line was completely blocked, the water level would overflow and flood the bathroom, so it is important to check your drain and sewer lines.

Another cause of toilet bubbles is a lack of proper venting. A household should install a separate vent for every drainpipe, as opposed to two separate ones. However, in some houses, the plumbing system is not functional enough to accommodate multiple drain pipes.

Solutions

Toilet bubbles can occur when the main drain pipe is partially or completely clogged. This prevents the waste from flowing out into the sewer line, which can lead to a backup. Eventually, the sewage will rise to the surface of the drain, causing it to back up. A partially clogged pipe is less likely to cause a backup, but it will cause bubbling while the toilet drains.

Another cause of toilet bubbles is an obstruction in the vent stack. Normally, this pipe helps vent sewer gases into the atmosphere. The vent stack is an extension of the main drain pipe, which is located on the roof of the house. If the vent stack is partially or completely blocked, it will create a negative pressure inside the drain.

Unclogging

When your toilet bubbles while draining the tub, it could be an indication of a larger problem. If this happens frequently, it may be a clog in the municipal sewer line, which carries waste away from your home. It is important to contact your local township or water company to report the clog. However, it may not be possible to find the problem unless you know exactly where it is located.

Toilets and bathtubs are connected to each other by concealed plumbing. This shared drain contains a vent pipe that leads to the outside of your house. This vent pipe is used to release sewer gases from the pipe, preventing pressure from building up inside it. When the vent pipe becomes partially blocked, air from the vent ends up leaking into the bathtub drain and causing bubbling.

Cleaning

If you are experiencing toilet bubbles when your tub drains, there are a few things you can do to avoid the problem. First, you need to check the clog. The problem can be caused by a clog in the drainpipe connecting the bathtub and toilet. If this is the case, you can use an enzyme-based drain cleaner to clear it. Another option is to use baking soda or peroxide to break up the clog. These methods will not harm your pipes and will ensure a proper drain.

Another possible cause is a clogged main drain pipe. This is when the waste in your tub or toilet fails to drain properly and is instead backed up in your home’s sewer system. If the main drain pipe is partially clogged, it will cause bubbles but will not result in a backup. The water in the bathtub will bubble because the space between the clog and the bathtub is filled with air.
