Bathtub Drain Makes Noise When Toilet Is Flushed: What Are the Causes?
Once someone flushes the toilet, the water flow gets into the sewer and pulls air from the tub to drain, generating a gurgling sound. To avoid this, ensure that the plumbing venting reaches over the roof.
In cold weather, simply apply hot water to the sinks and check the roof vent pipes to give them some moisture.
Moreover, observe the vents in the attic and determine if they are damaged or covered. If anything looks out of hand, you’ll need the services of a licensed plumber.
Apart from these, there are a few more reasons for producing gurgle sounds:
When the toilet is flushed, the bathtub drains gurgles for three reasons. They are as follows:
- Excessive air escaping from the drain
- The presence of air in the drain
Air Forced Through the Drains:
Air is forced through the drains when the vent becomes blocked. This creates pressure in various ways, which produces gurgling noises.
The air in:
The bathtub has air vents that regulate air quality. It travels through the pipes. While this is happening, many vents can get blocked, and the air gets trapped within the piping system.
P-traps are installed in bathtub plumbing systems to keep a particular quantity of water in the pipe. Whereas if the bathtub does not have a P-trap, air will easily flow whenever the toilet is flushed, causing a gurgling sound.
How To Fix the Gurgles Sound?
Now you’re aware of the various noise sources when flushing the toilet, let’s take a look at some of the possible solutions.
Pump Air Out Using a Plunger
Air trapped in the pipes is one of the causes of gurgling bathtub drains when flushing the toilet. But using a plunger will remove air from the pipes and drains and unlock the toilet.
It’s really a simple and quick way to solve any plumbing problem without contacting a plumber. To do this, a user needs a few items, such as duct tape and a plunger.
In this process, close the drains with duct tape. It will help to prevent air circulation in the drains and pipes. This procedure makes sure that the plungers are creating force inside the pipe.
Before starting, keep in mind that the plunger’s bowl is completely covered in water. So, continue plunging for a few minutes, flush the toilet and listen for the gurgling sound. If it’s still there, apply it once more.
Plunging removes all air or other blockages that have become locked in the drains or pipes.
Examine the Venting System
Unless there are difficulties with plunging. But you should keep an eye on the venting system. Because of the placement of the venting system, leaves and dirt sometimes get into the pipes and create problems.
In that case, you must clean the vent regularly to eliminate dirt and allow air to flow freely. Cleaning the pipes is not difficult, but it may demand some effort. It is worthwhile to stop the blocked vents issue.
For the consequences, a user may need a plumbing snake and a hose line or other substance that can push water through to the vents. Try inserting the plumbing snake through the vent pipe until you locate any things creating an issue.
Next, use the plumbing snake and work hard to simply eliminate the blockage. If using a hosepipe cannot solve the issue, repeat the process.
In case, someone has never seen a plumbing snake before. Then he may require the support of someone who is knowledgeable.
Raise the Pipe’s Diameter
Increase the diameter of the pipe as another probable solution to the gurgling problem. Excess toilet paper can be a stumbling block for a smaller pipe.
As a result, you must increase its diameter to guarantee that trash goes through without any barrier. Most toilet draining pipes have a diameter of 3 inches. For a better outcome, increase it to 4 inches so that more waste can pass through it.
A 4-inch pipe will also have to be attached to the main pipe. When you are prepared to work, the technique is not difficult. It is a wonderful DIY project that will save you a bunch of money. So, the increased pipe diameter is not just an “immediate approach,” but it can also help businesses in the long term.
