Most homeowners don’t think about their sewer system until something goes wrong. If you’ve ever had a drain backup or noticed a foul smell in your yard, you might have an issue with your private sewer lateral (PSL). Understanding what it is, how it works, and what to do when there’s a problem can save you time, stress, and money.
What Is a Private Sewer Lateral?
A private sewer lateral is an underground pipe that connects your home’s plumbing system to the main municipal sewer line. Every time you flush a toilet, wash dishes, or take a shower, wastewater flows through this pipe and into the city’s sewer system. The homeowner is typically responsible for maintaining and repairing this pipe for the portion that runs under their property.
In some areas, sewer laterals are divided into two sections:
- Upper lateral – Runs from the home to the sidewalk or property line. Almost always the homeowner’s responsibility.
- Lower lateral – Connects the upper lateral to the main sewer line, often beneath the street. Responsibility varies by location; some municipalities handle repairs, while others require homeowners to maintain it.
Common Problems with Private Sewer Laterals
Over time, sewer laterals can develop issues that lead to clogs, leaks, or even complete failure. Some of the most common problems include:
1. Tree Root Intrusion
Tree roots naturally seek out moisture and can invade sewer pipes through small cracks or joints. Once inside, they grow and expand, causing blockages and even breaking the pipe.
2. Aging or Deteriorating Pipes
Older homes may have sewer laterals made of clay, Orangeburg (a type of fiber conduit), or cast iron, all of which deteriorate over time. Cracked, collapsed, or corroded pipes can cause sewage backups and require repair or replacement.
3. Grease and Debris Buildup
Pouring grease, oil, and food waste down the drain leads to buildup inside the sewer lateral. Over time, this narrows the pipe’s interior, restricting flow and causing clogs.
4. Pipe Misalignment or Damage
Shifting soil, earthquakes, or construction near the pipe can cause it to shift, crack, or collapse. Even minor misalignments can lead to leaks and blockages.
5. Foreign Objects
Flushing non-flushable items like wipes, paper towels, hygiene products, and other debris can quickly clog the lateral, leading to backups.
Signs of a Sewer Lateral Problem
Detecting a sewer issue early can prevent costly damage and repairs. Watch for these warning signs:
- Slow-draining sinks, tubs, or toilets – If multiple drains are slow or backing up, it could indicate a sewer lateral clog.
- Gurgling sounds – Strange noises from toilets or drains may signal a blockage.
- Sewage backup – Water coming up through floor drains or toilets is a major red flag.
- Foul odors – A persistent sewer smell around your yard or home could indicate a leak.
- Soggy patches in the yard – If an area of your lawn is constantly wet or greener than the rest, it could be due to a leaking sewer pipe.
Diagnosing and Fixing Sewer Lateral Issues
If you suspect a problem with your private sewer lateral, it’s essential to call a professional plumber. Here’s what to expect:
Sewer Camera Inspection
A small, waterproof camera is inserted into the sewer line to inspect the condition of the pipe and locate any blockages, cracks, or other issues. This allows for an accurate diagnosis without unnecessary digging.
Clearing Clogs
If a clog is the issue, plumbers can use hydrojetting (high-pressure water) or an auger to remove blockages caused by grease, roots, or debris.
Pipe Repair or Replacement
For minor cracks or damage, trenchless repair methods like pipe lining or pipe bursting can fix the problem without digging up the entire yard. If the pipe is severely damaged, a full replacement may be necessary.
Preventing Sewer Lateral Problems
Taking care of your private sewer lateral can help you avoid costly repairs. Here are some tips:
- Avoid pouring grease or oil down the drain. Instead, let it solidify and dispose of it in the trash.
- Be mindful of what you flush. Only flush toilet paper; avoid wipes, paper towels, and hygiene products.
- Schedule regular sewer inspections. A professional inspection every few years can catch small problems before they become big ones.
- Plant trees away from sewer lines. Tree roots can be a major cause of pipe damage.
- Know your pipe material. If your home has older pipes, consider proactive replacement before they fail.
