sewer backup/ video inspectionIf you’ve ever had a sewer backup, you know it’s more than a minor inconvenience. This isn’t just a drain clog; it’s a full-on house disruptor. Imagine coming home to find your basement or yard transformed into a swamp of murky water.

Not only is it unpleasant, but it’s also costly to repair, can damage your property, and even brings health hazards. In this article, we will explore seven main causes of sewer backups. This way, you can know what to watch for and how to deal with each one.

Key Takeaways

  • Sewer backups are common but preventable with the right knowledge and habits.
  • Tree roots, aging pipes, and non-flushable items are leading causes.
  • Heavy rainfall and blockages in municipal systems can trigger backups even without homeowner error.
  • Regular inspections and responsible flushing habits can go a long way toward preventing sewer backups.
  • Professional plumbing services can provide solutions like root removal, pipe repair, and backflow prevention.

Common Causes of Sewer Backup

Tree Roots

Tree roots are the quiet culprits of sewer line trouble. You might think your beloved maple tree is just minding its business, but below ground, its roots are seeking moisture anywhere they can find it.

Sewer pipes, especially if they have the tiniest crack, can be like a water beacon for those thirsty roots. Over time, roots grow into the pipes, leading to blockages and even cracking them apart.

How can you spot this? Watch for slow drains, strange gurgling noises, or oddly green, lush patches of grass directly above your sewer line. If you’re noticing any of these, a root invasion could be underway.

Solution: Professional rooter services can clear roots from your sewer lines, and hydro jetting can blast them out without harming your pipes. For a more permanent fix, consider root barriers to keep roots away. If you’re planting new trees, keep them far from sewer lines, or pick plants with non-invasive roots to avoid future headaches.

Non-Flushable Items

Not everything can be flushed down the toilet, no matter what the packaging might claim. Wipes, paper towels, feminine products, and even grease poured down the drain may seem harmless at first, but they can create stubborn clogs.

“Flushable” wipes, in particular, are often anything but. Over time, these items can build up in your pipes, causing a nasty blockage.

Solution: Keep a plunger or drain snake on hand for small clogs, but for bigger issues, it’s wise to call in a plumber. To prevent clogs, avoid flushing anything but toilet paper and human waste. Drain screens are also a cheap and easy way to catch debris before it heads down the pipes.

Aging Sewer Lines

Let’s face it: nothing lasts forever, and that goes for sewer pipes too. Older homes often have pipes made of cast iron, clay, or even Orangeburg (a tar paper product), all of which degrade over time. When these pipes start to go, cracks, breaks, and collapses aren’t far behind, making backups a frequent problem.

Common warning signs include slow drainage, frequent backups, and a sewage-like odor around your property. If your home’s pipes are showing signs of age, it may be time for an inspection.

Solution: Depending on the damage, you might need a repair or full sewer line replacement. A professional inspection can tell you what you’re dealing with. Regular plumbing inspections are especially important in older homes where underground pipes have seen better days.

Heavy Rain and Flooding

After a heavy downpour, your city’s sewer system might be struggling to keep up. When the municipal sewer system becomes overloaded, the excess water has to go somewhere, and unfortunately, that somewhere could be your basement or first-floor drains.

You might notice water backing up in your basement or bathroom fixtures during or after heavy rain. This isn’t your home’s fault, it’s often a city issue.

Solution: To help manage rainwater, install a sump pump or backwater valve. These devices help direct water away from your home’s interior and reduce the impact of heavy rain. Regularly cleaning out your gutters and outdoor drains is another good habit to keep flooding at bay.

Sewer Line Bellies

Sometimes pipes don’t lay perfectly straight; they form bellies—dips or sags in the line where water and waste can pool. Over time, these low spots can collect debris and lead to blockages. Think of it as a sinkhole in your sewer line that traps everything trying to pass through.

Signs of a belly include recurrent backups or drains making odd gurgling sounds. If left unchecked, a belly can lead to more serious pipe issues.

Solution: Fixing a sewer line belly often requires a professional to dig and realign the pipe or use trenchless repair methods. Regular inspections can catch these sags before they become a bigger problem.

Broken or Collapsed Sewer Lines

Pipes can break for several reasons: shifting soil, corrosion, and outside pressures all take a toll over time. When a pipe collapses, your entire sewer line could be at risk, and backups are usually a constant battle.

How can you tell if your sewer line has collapsed? Watch for persistent backups, soggy patches in your yard, or an unmistakable sewage odor.

Solution: Depending on the pipe’s condition, trenchless pipe bursting might be an option to replace the line without digging up your yard. In other cases, traditional excavation and replacement are necessary. Keep an eye on any soil movement around your sewer lines, and schedule regular plumbing inspections to catch early signs of trouble.

Blockages in Municipal Sewer Systems

Sometimes, the problem isn’t even in your home’s plumbing. Blockages in the municipal sewer system can lead to backups in multiple homes on your street. You might notice sewage backing up in several drains at once, especially in low-lying areas like basements.

Solution: If you suspect a municipal blockage, contact your local utility provider. They’re responsible for fixing these larger sewer issues. For added protection, consider installing a backflow prevention device to keep sewage from coming into your home if the municipal system backs up.
