The good thing is that some of the methods we will be discussing here are pretty easy, while you may find one or two of them complex. 

Bottom line is that you are sure to find a method that you will be able to handle comfortably.

Let’s get get started!

 How To Unclog Sewer Line Through Toilet

1. The Hot Water Trick

Yep, I bet you didn’t know that something as common as water can be used to dislodge clogs in your sewer line. Even if you do not have all the other tools in carrying this duty out, as long as there is water, you have all that you need in some cases.

Get sufficient water and bring to a boil then, pour it through the drain line. Do so for about five minutes. 

We advise doing so periodically all through the day. This way, if there is any grease or any form of debris at all, it will be loosened by the hot water. The hot water strategy can suffice if it is the only option available however, it is not always guaranteed to work.

It usually works better if the sewer line is not blocked. Hot water can help to salvage the situation if the clog is not so tough.

2. The Plunger Method

Do you know about the force ball plunger? It is a magical tool used in loosening very tough clogs that hot water night is not able to handle in sewer lines.

The plunger can clear up clogs in your sewer line due to the super tight seal it develops with the drain. This tightness and the pressure it creates, aids in ejecting the clogs no matter how tough they are, out of the drains.

Ingredients needed for this procedure include the ball spring plunger and some water.


The first step you must take in unclogging the sewer line with a plunger is to check that there is sufficient running water in the toilet bowl.

This is because using water alongside the plunger is an effective combination in the removal of blockage from the main sewer lines.

They work together in dislodging the clog and clearing it completely.

For best results, use the plunger continuously until you are sure the clog has not only loosened but cleared successfully.

3. Unclogging Sewer Lines Using Baking Soda

In this method, we will be showing you how you can get sewer lines unclogged using a readily available household material – baking soda.

There are other natural remedies that you can use in unclogging sewer lines, however, the edge baking soda has over them all is that they are very potent and loosens even the toughest of clogs.

The ingredient needed for this procedure is baking soda and vinegar. A cup of it is all that you need, plus a cup of vinegar.


Step 1: Take a cup of baking soda and pour it down the drain.

Step 2: As soon as the baking soda is poured, follow up immediately with a cupful of vinegar.

Step 3: Exit the sewer line drains and wait for about 15 minutes for both the baking soda and vinegar to react within the drain and work on loosening the clogs.

Step 4: Return 15 minutes later and pour down some hot water into the drain. 

Hot water will help to fully clear away the clogs that must have been broken down by the baking soda mixture.

Another way to unclog sewer lines through the toilet is to not just do anything at all.

A novice going to unclog sewer lines with little or no skills or expertise will only compound the issue and rake up more expenses for themselves.

The only reasonable option to follow in this case will be to contact an expert to come to check it out and have it fixed subsequently.

This way, you can be sure that your sewer line will be properly fixed without you having to pay extra fees for self-inflicted issues.

4. Power Washer Method

This list would have been incomplete without a mention of one of the most trusted ways of dealing with clogs in main sewers.

The procedure might seem a lot to take in at first, but anyone who patiently reads and assimilates it will be thankful they did upon its implementation.

Two different methods can be used with the power washer. 

We will try and simplify it as much as possible below:

Method 1

Put on the water on your pressure washer. 

When you do this, the same water would not be able to run back via the sewer line.

Now that the water is on, slowly increase the water pressure. As you do, swing the better back and forth till the clog is cleared.

Doing so will make the power washer clear out the blockage completely from the main sewer line in due time.

Method 2

Carefully scrutinize the pipes to see where the screw on the cap is located. A heads-up will be to check the drainage lines or around the basement for the clean-out pipe.

As soon as you spot it, place a bowl under it then, open it.

The logic behind putting a bowl under it is so that you do not have a messy spill on your hands when it is removed. Instead, the wastewater pours into the bowl.

The next step will be to get your power washer’s trigger gun and connect a sewer jetter to it ensuring as you do, that it is lowered carefully into your home’s main sewer line. The key is to continue lowering until you get to the clog.

Once you get to the clog, the rest, as they say, is history.


Plumbing issues can be very disturbing! What is even more annoying is the fact that they are bound to happen no matter how careful one is as a result of mistakes and accidents here and there.

When there is a clog in your sewer line, the wise thing to do is to carefully observe to know the exact cause(s).

We would always advise that you get a professional to come get it fixed as they tend to be very skillful work but, familiarizing yourself with one or two proven methods would save you from spending so much on common plumbing issues such as this.
