Sewer lines are one of those hidden systems in a home that most people don’t think about—until something goes wrong.
In Potomac, Maryland, the mix of older homes, mature landscaping, and variable soil conditions creates a perfect storm for sewer line damage.
Whether you’re dealing with recurring drain clogs, a soggy lawn, or a nasty sewage smell, it could all point to issues brewing beneath your feet.
This article dives into the top causes of sewer line damage in Potomac homes, how to spot the early warning signs, and what homeowners can do to address problems before they turn into full-blown disasters.
One of the most common causes of sewer line damage in Potomac—especially in older neighborhoods with large, established trees—is tree root intrusion. Tree roots are naturally attracted to moisture and nutrients, which makes your sewer line an ideal target.
Over time, even a tiny crack in the pipe can invite roots to infiltrate, grow, and create a tangled blockage.
As the roots grow thicker and longer, they can cause significant structural damage to the pipe, cracking it or even causing complete collapse in severe cases.
The roots also trap debris, which can lead to slow drains or backups inside the home.
Many homeowners don’t realize this is happening until it’s too late. Regular sewer inspections are key if your property is surrounded by trees or shrubs.
Potomac is home to many beautiful older houses, but with those properties often come outdated plumbing systems. Sewer lines made from materials like clay, cast iron, or Orangeburg (a bitumen-based pipe used widely until the 1970s) are especially prone to wear and tear.
These older pipes can crack, corrode, or disintegrate over time. Cast iron pipes may rust from the inside out, while clay pipes are brittle and susceptible to pressure from above-ground weight or shifting soil.
As these materials degrade, leaks and collapses become more likely.
A video inspection is usually the best way to confirm the condition of your sewer line if you’re unsure of the material or age.
Although it’s not always talked about, soil shifting plays a big role in sewer line problems in Potomac.
Our region experiences seasonal changes in temperature, occasional freeze-thaw cycles, and varying moisture levels in the soil—all of which can cause the ground to expand and contract.
When this happens, sewer pipes may shift, bend, or break. In extreme cases, the pressure from shifting soil can cause misalignment in joints or completely separate sections of piping.
This kind of damage is often gradual, making it hard to detect until a major failure occurs.
Homes built on slopes or with recent landscaping changes are especially at risk. Proper grading and drainage around the home can help reduce this type of stress on your sewer system.
You’ve probably heard it before, but it bears repeating: never pour grease down your drains.
In colder weather, which Potomac sees a fair amount of, grease can quickly solidify inside your pipes, sticking to the inner walls and catching passing debris.
Over time, this forms thick blockages that restrict water flow and increase pressure inside the line.
Aside from grease, everyday items like paper towels, hygiene products, and even so-called “flushable” wipes don’t break down easily.
These materials can accumulate, causing clogs that put strain on your sewer line and potentially lead to cracks or breaks.
It only takes one major clog to back sewage up into your home, so being mindful of what goes down your drains is a simple but crucial way to prevent damage.
Not all sewer lines were installed with the same level of care. Some older homes in Potomac may have pipes that were laid using outdated methods or installed with minimal slope, preventing waste from flowing properly.
Poor pipe grading can result in waste pooling in the line, leading to increased corrosion and deterioration.
Also, patchwork repairs from previous plumbing jobs may not hold up over time. For example, a section of pipe that was replaced using inferior materials or fitted incorrectly could become a weak spot.
If the joints aren’t sealed tightly or the replacement didn’t restore full pipe integrity, the result can be chronic leaks or collapses.
These types of issues can be hard to detect without a professional inspection, especially if you’re not the first owner of your home.
Finally, nearby construction or roadwork can also impact your sewer lines. Large equipment creates vibrations that can shift soil and damage nearby pipes.
If your home is near an active construction zone—or if you’ve done major remodeling or excavation work on your property—it’s worth checking in on the condition of your sewer line afterward.
Sewer pipes weren’t built to withstand that kind of ground disturbance.
You may not notice damage right away, but subtle shifts can add up quickly, especially when paired with other common risks like aging infrastructure or root invasion.
No one wants to deal with a sewer backup or a costly line replacement. But understanding the root causes of sewer line damage in Potomac homes is the first step to preventing these headaches.
