What Are The Best Tree Root Killers for Sewer Lines?
Laws vary from state to state regarding the depth of sewer lines, and numerous variables come to play, including the frost depth. The deeper the sewer line, the safer the sewer lines remain (generally).
Some trees cause more damage than others.
Trees that cause especially significant damage include:
Of course, nobody wants to get rid of a gorgeous tree that’s already standing simply to protect plumbing pipes or their septic tank system.
Part of caring for your tree and your home’s plumbing involves keeping tabs on that beautiful tree’s roots.
Tree Roots and Sewer Line Pipe Damage
Trees require nutrients and water in order to grow, of course.
Growing trees and full-grown trees in need of water naturally send out their roots to find water. If your pipes happen to be the nearest source of water, your tree will attempt to infiltrate your pipes.
Pipe sections in the sewer lateral that already contain cracks present more of an opportunity than secure pipes, but roots can break into pipes, even if they don’t have a crack.
Unlike other materials you may find in your pipes such as hair clogs or soap scum, tree roots tend to be more stubborn to remove and cause much more damage due to their size and strength.
This is behind the need for trenchless sewer line repair since pipe damage is often out of reach and otherwise expensive to get to.
Just check out the video below to see the size of the roots some plumbers encounter!
Once roots get into your pipe, they can wreak havoc in the form of a clogged pipe and an underground pipe leak.
If the tree roots clog a drain pipe or main sewer line, you may experience fixtures that won’t drain properly and backflow into your sink or toilet bowl.
If tree roots block or damage a supply line, you may notice decreased water flow into your home until the point of absolutely no water flow at all.
A leak can cause significant water waste, increasing your water bill (if you get your water from the city). It can also potentially flood your yard or damage your landscaping.
Prevent root damage by planting new trees thoughtfully and keeping trees watered. If you suspect tree roots in your pipe, you can use a camera for inspection.
Root killers are never safe around children and pets. Wear protective gloves, masks, goggles, and full-coverage clothing to prevent toxins from causing skin irritation. See this post for more perspective and detail on how to get rid of tree roots in a sewer line.
What Are The Different Types of Root Killers for Sewer Lines?
Foam Root Killer
Foam root killer tends to work much faster and more effectively than copper sulfate. They also don’t damage your sewer system. However, they cost much more, and you need to mix the concentrate with water.
You will need to use a foam root killer if the blockage has already occurred.
Copper Sulfate Root Killer
Copper sulfate root killer provides an inexpensive solution compared to foam root killers, but it can cause damage to your home’s plumbing if copper levels get too high.
Copper sulfate works best as maintenance as opposed to clearing up a stubborn clog.
How Do Tree Root Killers Work for Sewer Lines and Drains Work?
Sewer line root killers use chemicals to eat at the roots that may have gotten into your sewer lines and drains.
You should always apply a root killer at the first sign of a problem instead of waiting for complete blockage.
Always follow directions exactly as indicated on your product.
In most cases, you will use the root killer by pouring it into your toilet or into the affected line directly (if you have access).
Some products only work on living material and may not work on dead roots.
If you have trees near your underground pipes, make a point to use your preferred root killer as directed as part of your regular plumbing maintenance routine.
