The whole process is based on producing tons of foam once the product mixes with water. This foam then goes through the pipe, covering the entire length, and then it starts killing the root(s) once it touches it.

What stands out about this foaming agent is the capacity to kill the roots on the pipes without harming nearby trees. Similarly, it stops new root growth by affecting the living tissue of the root to keep it from growing in the same direction.

And if all that wasn’t enough, you still get the chance to use it on any type of plumbing. Along with easy liquid composition, it becomes a real piece of cake to use.

  • Factors to Consider While Buying a Sewer Line Root Killer

    It takes some experience to get the best sewer line root killer for cleaning your sewer line. But getting this experience can take a lot of time, especially if you don’t have much to spare. Luckily, we can save you all that time with this guide.

    Below, you’ll find all the factors to consider before picking a sewer line root killer.

    • Formula & Ingredients

    There are two types of formulas to consider. These are copper sulfate and foaming root killers. Both options are pretty effective, but they work entirely differently.

    Copper sulfate, for example, is the most popular. But it is essential to know that copper sulfate comes in crystals. It is an excellent choice if the root problem is not too big, but you still need an effective product.

    Then you will find foaming roots that also come in a powder-like or liquid presentation. Similarly, you will have to pour it into the sewer line to get the job done. But it works better for difficult clogs that copper sulfate may not be able to fix.

    Don’t overlook those formulas with extra ingredients like dichlobenil, which can help to get the job done faster. These ingredients are pretty corrosive, though, so you’ll have to be careful with products that contain these.

    • Method of Action

    What’s the method of action of the product you’re getting? Here, it all depends on whether you pick copper sulfate pentahydrate or foaming killer.

    The first works effectively when flushed through a toilet that connects to the sewer line. It usually gets the job done within 2 weeks.

    The foaming killer is almost the same. This one becomes foam when it gets in contact with water (this process takes a few hours) after you flush it. The advantage is that it covers the entire pipe, killing the roots on the bottom and top of the line.

    • Effectiveness & Power

    The effectiveness of both formulas is pretty high. However, you’ll want to know whether it works fast enough.

    That’s why foam root killer is often the way to go if you’re looking for a fast product. It gets the job done a bit faster than copper sulfate and usually covers more surface area too.

    But copper sulfate has a lot more to offer than just killing roots. It also works as a metal cleaner, getting rid of not only the root but also grease and gunk in the sewer line. After using it, the pipes will be a lot cleaner and less likely to clog in the future.

    • Overall Safety 

    Apart from all that, be sure to know that all these products are super-toxic. But some are a bit more toxic than others, as well as more difficult to apply. You’ll have to be careful with those.

    We recommend going for easy-to-grab and pour bottles. You don’t need to pick something that will eventually be too hard to use or become a potential danger to your health.

    • Container Size 

    Lastly, consider how big of a container you’re going for. It is important to note because, in either foam or copper sulfate presentation, you’re likely to use about 1 pound of the product per application. So the more you have, the more it will last, and the more times you can use it.

    That’s why we heavily recommend options that offer between 2 to 4 pounds of the total product. That doesn’t mean a 1-pound bottle is not worth considering, but it will probably only last one application. And usually, you need more than that.

    Do Root Killers Work in Sewer lines? 

    Yes, you can use a root killer for pipes and clean them off any obstruction that may be clogging the pipes.

    Of course, the killing won’t be immediate, and the root will probably grow again after several months. But even then, a root killer will get rid of most small roots inside your sewer plumbing without problems.

    How do I Get Rid of Roots in my Sewer Line? 

    If a root killer doesn’t get the job done, there are many other methods you can try to get rid of the obstruction. Here are some of them:

    • Mechanical Auger

    Let’s say you know where the roots are located, and you have close access to that part. In that case, nothing will help you more than a mechanical auger.

    It is like a standard auger but with a mechanical system that cooks roots and other solid materials on the sewer lines. You can use it after the root killer for flushing the remains out.

    • Hydro Jetter

    The machine sounds weird, but it works wonders. It uses a pump with pressurized water to push the roots out of the piping.

    This machine gets the job done when you have thin roots on the sewer line alongside other obstructions. Alongside a root killer, this machine works like a charm.

    • Digging the Pipe Out

    Also known as the trenching method, it is all about digging a hole in the house wherever the clogged pipe is located. Then, you will need to get it out and replace it with a new one.

    This process is not only more exhausting, but it could also be a lot more expensive. However, it is always only useful if the pipes are already broken from the roots. Otherwise, try the other methods first.

    • Hire a Plumber

    If you don’t want to do the job, then you can always hire a professional to do it for you. An expert plumber could be precisely that.

    Using tools like cameras and augers, plus his knowledge and experience with sewer lines, a plumber may be costly but will save you tons of time and effort.
