Toolbox or Accessories for Toilet Gurgle Fixes

I know you don’t want to do this work but this is very important for the better functioning of your toilet.

So before getting into this you need some basic tools to work comfortably like:

  1.  Toilet Plunger
  2. drain snake combo

Moreover, If you don’t want to put lots of effort into this then the Chemical drain dissolver  is the right choice for you to clean the drain pipes. Alternatively, toilet bleach and brush is not also a bad idea to clean this mess and I think you have these.

Be also prepared with below just in case:

  • Need a towel and rags to prevent spills of water
  • Make sure to seal off the drains before plunging the toilet
  • You can use duct tape to seal the drains or if you have more pluggers then this also a good choice.

So these are some of the basic tools that would help you to solve your toilet problem. After you figure out what is the main problem behind this gurgling and bubbling noise.

Then you might need some other things, for example, you have to replace the water inlet line and flushing system if you notice that this is the main source of all the problems.

But first, let’s check out what things make your toilet gurgle and bubbles.

What Makes Toilet Gurgle, Bubbles How To Fix Them

If you feel that your toilet drains slowly, make bubbles and gurgles this indicates that you have a blockage in the drain pipes and you need to clean up.

In short, this blockage causes negative air pressure or suction in your plumbing. That’s why air comes back into the toilet and this will make gurgling and bubbling noise.

But this is not the only one cause you have to face, you need to consider the other problems as well.

#1: Fix the Air Bubble In The Toilet Drain Pipes

Air bubbles are also a very normal thing that makes a very important role in our plumbing system. Thanks to the P-trap and S-trap. That is the standing position of your toilet that prevents gases and smells that come from the sewer.

These traps are working as a barrier in the toilet system so that all the wastes can’t come back to the toilet. Then where are these air bubbles coming from?

So these bubbles are coming from the toilet tank and that pipe that brings water to the toilet. Not the pipe that brings the waste to the sewer.

That’s why you are hearing these bubbling sounds coming from your toilet. But wait is this reason also responsible for the gurgling sound?

I am pretty sure this sound is coming only when refilling the toilet tank otherwise it is not supposed to be produced.

So when you are refilling your toilet tank, these bubbles would find their way to disrupt the water source. How you can fix them so just follow these ways:

It is very easy to come out these bubbles just turn on the faucet then the water line keeps them out until you stop this faucet.

But the next time you will do the same then that gurgling sound most probably can’t come out or if it is still coming then the pipe may have an issue.

Next problem, please.

#2: Empty Clogged Vent Stack

If everything seems good in the drain pipes then this problem might be coming from the vent pipe so you need to check the pipe.

These types of vent pipes that connect to the roof are especially seen in the American standard toilets. I suggest you cover the top of the vent pipe from forged because in most cases small little birds made their nest on it, or bats also made this place for their sleep.

Before getting over the roof you need to check the pipe first because reptiles also might be there in it. This type of pipe is a good place for any small animals, especially reptiles. So be careful!. These types of things will definitely restrict the airflow in the vent pipes.

After looking at the vent pipe now it’s time to clean it. What you will need is just a flashlight, rope, air compressor (if you have one).

1st Step, Tie the flashlight with rope and let it down in the vent pipe, and check it carefully. Is something in it or not? After checking if you notice something is in the vent pipe then let’s move on to the next step.

2nd Step, as you know air compressor pushes high-pressure air so if something in the air vent then it will definitely go out through the sewer. If you have the air compressor then you can use otherwise normal water pressure can also do the same work.

Your work finished in the air vent cleaning, now it’s time to check the toilet clog.

#3: Identify the Reason and Fix Toilet Clogs

This is one of the common problems why your toilet gurgling at end of a flush, most people face this problem in their toilets.

Why do they face this problem so it might be breaking the flushed water passing through the pipes? That’s why you see something is coming back in your toilet at the end that your toilet started gurgling.

This will happen because of a weak flushing system but the modern toilets have a dual flushing system so that nothing will clog into the drain pipes. But if you don’t have these modern systems then read it fully.

Realistically, you can solve this problem without any plumber because this is not a big problem. Just follow these steps below and you will solve it. You need some tools that I have listed above, toilet plunger, drain snake combo, and chemical drain dissolver. These tools will help you with it.

After packing the toolbox let’s jump to the easy steps:

1st step, seal all the nearby drains and plunge your toilet because this will increase the air pressure inside the pipe.

Note: make sure to seal all the drains in the sink, bathroom, shower, and so on.

2nd step, tap the toilet drain by taping by rubber plungers. if it doesn’t work then you need a drain snake to dislodge the toilet pipe. This will 100% work.

Note: do not flush anything if that doesn’t look like waste or toilet paper.

Let’s move to the next step.

#4: Remove the Calcifying Elements

After solving these 3 problems if your toilet is still making these gurgles and bubbles then something is not good in your toilet tank and you should check it. 

So just open your toilet tank and look into the walls and the watercolor in the toilet tank, if it is not looking normal. I mean if your toilet tank walls and watercolor got reddish. Then you are facing sediment buildup or you can also say calcifying elements.

Basically, if the water in the toilet tank contains iron, magnesium, or calcium so it is not a good signal. You need to clean it very soon because this will increase very fast and it could block the water from entering the tank.

Also, it will cause a gurgling sound when you fill the tank. But this is not the end you need to clean it weekly because your water has these elements that’s why it will build again. 

Don’t worry this is a normal problem and you can do it so follow these ways:

  1. Just put a scrubbing brush and bleach solution then clean it properly so it should break down the bacteria and these minerals as well.

Let’s jump to the 5th and last problem.

#5: Quickly Fix the  Faulty Tank System 

How do you know if your toilet tank system is not working properly? This will make your work hard because you don’t know how a faulty tank system behaves. Watch this video and you will understand the working of a proper running tank system.

After watching this video now you probably understand how your toilet system works. There are simple 2 main mechanisms in the toilet tank: the first one is for releasing the water to the toilet bowl and the second one is for refilling the tank.

Both activate when you tap on the flush. This first is also connected with the valve and the flush and the second one is connected to the pipe so when you press the flush lever both work at the same time.

So your whole toilet tank depends on these 2 elements then you need to check them first if the gurgling sound is coming out.

As seen in this video, water is spraying in all directions because of its faulty fill valve, however, it might be the cause for this bubbling sound also.

If you find this is the main reason behind this gurgling and bubbling sound then you should use these Universal fill flapper repair tool kits that will help you in this work.

So if you find a solution to your problem then this is great. 

After solving all these problems if you still notice the same problem then you have to call the plumber to fix the issue. As we discussed the major problems, not all the problems.
