Root access issues can be extremely baffling and costly to determine. Fortunately, root problems can be managed with copper sulfate or Foaming Root Killer (FRK). You need to pick the one that suits your particular circumstance. These two root killer products kill obtrusive roots yet don’t “consume” or “erode” the underlying foundations of the framework. When the root has been destroyed, organisms will begin to deteriorate in this microbes-rich climate. I will discuss the foaming root killer vs. copper sulfate.

If you have a septic tank and a drainage channel or a floor drain opening and have root problems, you should try the Foaming Root Killer (FRK), regardless of whether they are already blocked or not.

Foamy Root Killer vs. Copper Sulfate

Foaming Root KillerCopper Sulphate
It contains Diclobenil which kills the roots and prevents newCopper sulfate is a chemical made from copper compounds in combination with sulfuric acid.
Foaming tree root killer is a more modern invention used nowadays.It is a traditionalized Product used before the advent of foamy root killer
It self-foams in contact with water. If the foamy root killer can’t get to the roots, it can’t kill them.It accumulates as a heavy metal precipitate once it is applied to water.
The foam sticks the root-killing herbicide to the top of the pipe and roots above the flow.Copper Sulfate will kill roots if it gets on the roots, however since it sits at the bottom of the pipe the flow in the pipe will continue to move the copper out of the pipe
It should take foamy root killer from 2 days to 1 week to clear your line) Your system must have some flow in order for the foaming root killer to work properly.After roots have accumulated copper sulfate takes usually 3-4 weeks before the roots will die and begin to decay, and water flow should increase.

Copper Sulfate

If necessary, copper sulfate can be used to destroy irritating roots and restore the system’s normal functioning. This product works without affecting the surrounding trees, ground cover, or natural bacteria in the septic tank or cesspool. However, if your system has no flow, it will need to be mechanically cleaned before the copper sulfate treatment is performed. The reason is, if copper sulfate can’t reach the roots, it can’t kill them. Copper sulfate should clean the root system for 2 days to 2 weeks. The time required depends on the severity of the underlying problem and the location of the problem. If you need to root the system, wait 3-4 weeks before applying copper sulfate.

Some of you may be using Foaming Root Killer. If you have a septic tank and the roots infiltrate the main drain line (the pipes through which the sewer pipe enters the septic tank) or the reservoir itself, you will need to use Killer Root Foam to kill these pipes invasive roots.

Foaming Root Killer (FRK)

This unique foamy sulfate-free root remover foams in contact with water for better results. This product also contains ingredients that help accelerate the breakdown of the roots it kills. This allows you to solve root problems quickly. (You need Foamy Root Killer, 2 days to 1 week to clean the line) Your system must have a specific thread for Foamy Root Killer to work properly. If the foamy root killer can’t get to the roots, it can’t kill them.

To prevent roots from pushing up and damaging paved structures, trim the edge of the structure 3 inches or more and pour the Roebic Foaming Root Killer onto a thin strip. Repeat this process every year to prevent surface root growth along sidewalks and side streets. Between the roots and the sewer pipes: With water or a mechanical drilling machine, several small holes can be drilled to prevent long-lasting roots from growing the tree into the sewer pipes in the ground next to the dangerous tree or outside seams of the tree sewage system.

Add Roebic Foaming Root Killer to the holes and cover with soil. Make sure the hole and the depth of the hole are between the floor drain and the sewer pipe.

With regular use, both copper sulfate and root foam will keep the system root-free and prevent the discomfort of root clogging, such as overlaps and surface cracks.

Instructions on Homemade Root Killer for Sewer Lines

Sewage can be a waste for you, but the roots that grow near the sewer pipe are nutritious and need one of the small holes in the pipe to reach this spot. Once they are big enough, toilets and waste tanks have been created that run slowly. Plumbing professionals should handle the most effective killing chemicals, but you can make your available root killing chemicals to combat them.

Clear root killers

The roots usually penetrate the top sewer pipes, so chemicals that bind to the water can pass through the entire pipes without contacting them. Professional plumbers fix this with a foaming mixture of chemicals, and you can buy a less toxic compound than most home and garden centers online use. It contains diclobenil, which is also safe for septic systems. If you don’t want to inject this chemical into a septic tank or municipal waste disposal system, you can use one of the traditional alternatives – rock salt or copper sulfate.

Crystal Root Killer

The situation should improve both copper sulfate, which you can buy in crystalline form at the hardware store, and rock salt, which destroys the roots on contact, and if the pipe runs slowly, throw it in one of the lower toilets in the household. Copper sulfate is best when you pour around 1/2 cup of precious stones into the latrine and flush it a few times. The same amount of rock salt is also effective, especially if you take the time to break into smaller crystals with a hammer before rinsing. These chemicals are especially effective in clay pipes because they penetrate the clay and prevent new roots.

Homemade foam root killer

You can add a foaming effect to the saline solution by adding baking soda and vinegar. To make this organic carrot, mix a cup of table salt, baking soda, vinegar, and boiling water and immediately pour it into the toilet. 

After mixing, baking soda and vinegar begin to swell, and grinding allows the solution to fill the pipes so that salt can enter the clogged roots. The solution will kill the roots on contact, but the dead tree roots will disappear slowly, so you won’t notice immediate results.

Prevention of root invasions

Once your roots block the gutter, you can kill them, but you cannot remove them quickly. To prevent further blockage, it is best to keep the roots aside. One method is to saturate the soil around the pipeline with a root remover such as copper sulfate. To do this:

  • Dig a small or deep hole or row of holes near a flat piece of pipe.
  • Insert a 1.5-inch tube into each well, pour copper sulfate crystals into the tubes, and pour boiling water over the tubes.
  • Cover the tubes and leave them in place so that the treatment can be repeated regularly.
