Sewer Backup Repair

A sewage backup poses a serious health risk in your home. When your primary drain fails, wastewater can overflow from sinks, tubs, and toilets as it searches for a new path. Preferred Home Services provides emergency sewer restoration across the South Carolina Lowcountry to stop these overflows and protect your family. Our specialists arrive with the right tools to identify the bottleneck and get your drains working again today.
Your home deserves immediate protection. Stop the backup and secure your priority repair before the damage spreads. Request Same-Day Emergency Service!

Indicators of a Mainline Failure
Recognizing early warning signals allows you to act before an expensive cleanup becomes necessary. Your plumbing will usually signal a problem before a total backup happens. If your home shows these irregularities, the system needs a professional look.
- Gurgling sounds exiting your drains indicate air is trapped behind a growing obstruction.
- Foul odors from your sinks or showers indicate that water seals are failing due to line pressure.
- Widespread slow drains occurring simultaneously indicate the blockage is in the main line.
- Water rising in the tub as you flush the toilet is a clear signal of a bottleneck.
- Frequent overflow indicates a deep blockage that a plunger cannot reach.
- Soggy lawn spots over the buried pipe reveal a leak or a crushed line.
Technical Causes of Sewer Backups
Preventing a recurrence starts with knowing why your drains stopped. Most sewer failures in the Lowcountry occur because of three common issues.
Invasive Tree Roots
Roots are naturally drawn to the moisture inside sewer pipe joints. Once they find a tiny crack, they grow into a thick mass that eventually blocks all waste. This creates a physical barrier that only mechanical clearing can resolve.
Accumulated Debris and Grease
Over time, cooking oils and hair collect inside your pipes. This buildup creates a sticky surface that catches more debris until the pipe is completely sealed. Flushable wipes are also a major contributor to these clogs.
Aging or Damaged Pipes
Many older homes rely on cast iron or clay pipes that eventually sag, crack, or collapse. As wet coastal soil shifts, these weakened sections fail, causing a backup. This often requires a more permanent restoration to prevent future failures.
How We Restore Your Sewer Line
We use a high-precision process to clear your lines and verify that the issue is resolved. Our technicians focus on long-term results rather than temporary fixes.
- Mechanical Clearing: We use heavy-duty equipment to break through the initial blockage and restore flow.
- Visual Diagnostics: A high-definition camera travels into the pipe to identify the exact cause of the backup.
- Pressure Testing: We verify that the system can handle the daily wastewater volume without leaking from the joints.
- Action Plan: We provide clear options for repair or replacement if structural damage is identified.
Effective Strategies to Prevent Future Backups
Proactive care is the best way to keep your plumbing system working correctly for years. You can significantly reduce the risk of a sewage crisis by adopting a few simple habits.
- Practice Proper Waste Disposal: Avoid flushing anything other than toilet paper and organic waste down your toilets.
- Manage Grease and Oils: Never pour cooking fats down the kitchen sink, as they solidify and trap other debris in the line.
- Install Backflow Prevention: These valves act as mechanical gates that prevent municipal sewage from entering your home.
- Schedule Regular Maintenance: Yearly inspections can catch root growth before it becomes a total blockage.
Taking these steps preserves the structural integrity of your pipes and prevents unexpected repair costs.
