DIY Fixes for a Bathtub Drain Gurgles When Toilet Is Flushed

Everyone needs to use the toilet, agree! But there is nothing more embarrassing when a visitor uses it. They flush the can and the bathtub drain gurgles. Is this happening in your home? There is no need to go into a panic state or feel embarrassed. It happens to everyone, and you can fix the problem. The best is you do not need a plumber to help and can fix it yourself with some simple troubleshooting and tips.

Why Does This Happen That a Bathtub Drain Gurgle When Toilet Is Flushed

A bathroom drain gurgling can be annoying, especially when using it at night waking up the household. The only visible problem is the noise, but leave it be; it can become a huge problem. So if you hear this disturbing sound, it helps resolve it by determining what is causing the concern. For example, a gurgling bathtub drain can result from:

  • Air in the pipes is a common concern that can get clogged by dirt entering the piping system. The valve makes sure no air goes through to the water, but the air moves into the water when blocked, causing the sound.
  • The P-trap piping system provides the right amount of water to exit and traps the air as well. If your bath does not have this function, the air flows through when flushing the pot, making the gurgling sound. The main reason is the air moving in or out of the part, and if the vents are clogged, the noise is more.
  • Lastly, the air is coming out of the drain as the air needs to pass through the vents. This happens when a vent is clogged and the air forces through the drains. It creates pressure on the barrier closing it.

How Do You Solve Your Bathtub Gurgling Drain Problem

The solution is simple, to fix a bathtub drain gurgle when the toilet is flushed. Even if you are not experienced, you can fix it yourself. The first thing is to rid it from anything in the venting system to help unclog the pipe. Here are some tested ways to help quieten your gurgling drains.

Use a Plunger

You can use a plunger such as the Mr. Clean Combo from Amazon comprising a plunger and bowl brush caddy to remove objects blocking the pipe in amenities. Plunging helps unclog your can and removes the stuck air in the pipes. But before you proceed to plunge, close your tub drain first. Ensure that all other drains are closed from your shower to sinks. Next, you can use a piece of tape, allowing the air to move through the vents instead of the drain. Check out this video to help:

Make Sure to Keep the Venting System Clean Regularly

Doing this helps to fix bathtub drain gurgles when toilet is flushed, even if you have no gurgling noise present. It helps prevent problems from arising and allows the air to move freely through the vents and the drains. The important thing is always to check the central vent to avoid the other vents from clogging. Remove obstructions that could cause a clogged drain. You can use a high-pressure water pump or hosepipe to do this.

A Handy Device The Plumbing Snake

Compared to using a hosepipe or a wire, a plumbing snake is a handy tool to have for unclogging any drain around the home. If a clog is deeper in the pipe, this apparatus works better than using a hosepipe. You insert it into the vent slowly and keep pushing until it stops at the clog. You then move it back and forth until it breaks through the clog.

Once broken through, you can run water through pipes to see if it has fixed the problem. If not, repeat the process and push the apparatus until you are happy with the results.
