How to Keep Tree Roots Out of Drain Lines

Tree root intrusion is one of the biggest challenges for drain lines. They can end up in a pipeline in their quest for nutrients and grow so large that they cause a blockage. Homeowners have to replace their pipes to fix the issue, but preventing it is a much better solution.

In this entry, we’ll list several methods to stop tree roots from penetrating drain lines.

How can tree root intrusion into pipelines be prevented?

The most important step a homeowner can take to prevent tree root problems is to install heavy-duty pipes. When fixing an existing pipe or installing a new one, cast iron pipes are the ideal solution. It is a strong material that won’t develop holes through which tree roots can enter.

Another great solution is PVC. However, it can only be installed if the plumbing code permits it.

Putting barriers around the pipes is another useful strategy. The barriers can be chemical or physical. For instance, residential buildings commonly use copper sulfate and potassium hydroxide as their chemical barriers. This way, tree roots won’t get to sewage pipes and damage them.

Metal and wood are also powerful barriers. Still, their installation can be quite tricky and take a lot of time.

Finally, plant trees with a shallow root structure. Such trees are less likely to damage a pipeline. Large trees with massive roots should be planted as far away from pipelines as possible.

How can you remove tree roots from a drain line?

There are three main methods of eliminating tree roots from drain lines:

Physical action

Removing the roots from the pipes, replacing, or lining them is the first strategy for eliminating tree roots. If the pipes are aging and could collapse, replacing them is the safest way to proceed.

Lining old pipes is also an option, and there are two ways of doing it: slip-lining or using an inflatable liner. Bear in mind that pipe lining is expensive and should be used when tree removal and pipe replacement are unfeasible.

Mechanical action

Mechanical action has to do with cutting roots out of drain lines with cutters and augers. The method can also include pulling scrapers and abrasive brushes through waste lines with winches. However, since trees regrow even harder roots after the old ones have been cut off, mechanical action is often used in unison with another tactic.

Chemical action

Plumbers and homeowners pour copper sulfate into the toilet to combat root growth. However, it isn’t always effective because it doesn’t linger in the pipeline for very long. Filling pipelines with foam containing dichlobenil and metam-sodium is typically more reliable.

Root out your drain line problem

Overall, drain lines need proper protection, such as strong materials and barriers, to avoid being penetrated by tree roots. Nonetheless, if they end up in a pipeline, don’t stand idly by while the roots wreak havoc on the line. Instead, take appropriate action right away and prevent further harm.
