Best Sewer Line Root Killer

Now and then people come across the issue of sewer roots. The obstacle of sewer roots, clogged drains, and tree roots infestation will cause trouble for you.

If you leave this issue without any further action, the growing roots from the trees will ultimately clog the drains. Even further, the roots from the trees can destroy and collapse the sewer lines. It surely can cost you a thousand dollars for a fix [Fletch-Barney, LLC]. Instead of being ignorant, doing some flushes regularly can save you some money and prevent such a loss.

These 10 picks are the best sewer line root killer products that you could use to kill those roots.

They are actually divided into two types of root killer. One is by using rock salt or copper sulfate [Terry’s Plumbing], and the other is by using foaming dichlobenil pesticide. It could be hard to reach the top side of the pipe by using the copper sulfate. In contrast, a foaming root killer can reach that area [Chris Deziel, Hunker].

You also need to consider the best sewer line root killer for your situation. Some chemicals can kill the entire tree while others don’t. And some products can work significantly but they may be harmful so that proper care of use is required.

How to Choose the Right Root Killer for You

When it comes to removing the roots which penetrate into the sewer pipe, it’s hard to do with a knife or other sharp tools. However, things become so much easier when we use a particular chemical product that is designed to kill the roots. There is some consideration when selecting the right root killer for the sewer system.

1. Type of Root Killer

You have to define your sewer issue before deciding to buy a root killer. Are the roots really clogging the system? That means if the roots accumulate heavily in the pipe, then you have to dissolve them as soon as possible. In this case, a copper sulfate-based product can solve the issue.

However, when it comes to preventing the roots from growing, the foaming root killer is the best choice to pick because it’s able to reach every side inside the pipe.

2. Check Whether It is Permitted in your Region?

Some chemical productS may be banned in a certain state inside the US. You have to make a proper check before buying whether the root killer you are going to buy is permitted or not.

3. Will It Kill the Tree?

You may be concerned that this chemical-based root killer will kill the tree as well. The best sewer line root killer has to kill the roots, not the tree.

4. Is It Safe for Human?

Some products may contain these chemical compounds such as diquat dibromide and metam sodium. Metam sodium is restricted to use for sewer root from 1996. This is due to the potential health issue it can cause to humans, animals, and the environment. [Source]

What if the Root Killer doesn’t Work?

If you find the roots very stubborn to kill, you may need some further inspection. Perhaps, it’s not root that clogs your sewer line.

You could use a sewer camera and a sonde locator.

The camera will inspect what happens inside the sewer line by capturing the image and recording the video.

While the sonde locator functions to locate the position of the clog. This locator will pinpoint the position of the sonde that is attached to the camera head of your sewer camera. As the camera is close to or even exactly at the clogged point, pinpointing the sonde means pinpointing the clogged area.

A cheaper way can be done by using a flushable sonde. The kind of sonde will be flushed along the pipe. It will float on the water and stop at where the clogged point is.

These are the example of flushable sondes:

  1. Prototek FTP-8 (the affordable one)
  2. Ridgid 19793 Floating Transmitter (more expensive one)

The combination of these two tools is very critical for your sewer line maintenance. To be honest, if you compare the price of hiring a plumber to the price of purchasing a unit of a sewer camera, you’ll know buying the camera is way more saving. The price of a sewer camera is about twice of hiring a plumber. If you regularly inspect the sewer pipe, then this is a good investment.


The sewer roots, dirty ponds, algae, pests, and fungus are all filled with bacteria. If not taken care of properly, the bacteria can outburst. Therefore, it is important to clean the ponds, kill the sewer roots, and control the pests as well.

However, you do not want to harm the environment, as well as the trees. Therefore, it is better to find a sewer roots killer that can work effectively and safely to kill the sewer roots but does not harm the trees. You can find multiple products on the market, that can fit your specifications.

The above list of the best sewer line root killer will help you find the best quality, effective sewer root killer. But, if you are still struggling to find your best one, then we would prefer to suggest Sanco Industries Root Destroyer Copper Sulfate Pentahydrate as we have mentioned before. It’s effective, easy to use, and affordable. However, if you are not happy with the result, you expect to kill all the roots, then RootX foaming killer can kill all the roots with its foaming method.
