6 Signs You Need Sewer Line Repair
June 30, 2026 · 5 min read
Your main sewer line carries waste away from your entire home, so when it starts to fail, the whole house feels it. The tricky part is telling a sewer line problem apart from an ordinary clog. These six signs point to the main line — and mean it's time for a professional look before a small issue becomes a backup.
1. Multiple drains are slow at once
A single slow drain is usually a local clog. But when several fixtures — sinks, tubs, and toilets — are all slow or backing up together, the blockage is likely in the main line they all share.
2. Gurgling toilets and drains
If your toilet gurgles or bubbles when you run the sink or the washing machine, air is trapped in the line — a classic sign of a main-line obstruction.
3. Sewage odors
A healthy sewer system is sealed and vented, so you shouldn't smell it. Persistent sewage odor inside the home or in the yard often means a crack or break in the line.
4. Soggy or unusually green yard patches
A leaking sewer line acts like fertilizer and moisture underground. If one patch of your yard is suddenly lush, sunken, or soggy for no reason, the line beneath it may be broken.
5. Recurring, whole-home backups
If you're plunging and snaking the same backup again and again, the real problem is probably deeper in the main line — not the fixture you keep clearing.
6. Sewage backing up in the lowest drain
When wastewater comes up through the lowest drain in the house — often a basement or a ground-floor shower — the main line is blocked and needs attention right away.
What causes sewer line problems?
- Tree-root intrusion — roots seek moisture and crack older clay or cast-iron pipe.
- Aging pipe — decades-old lines corrode, crack, or collapse.
- Bellies — a section that sags and collects waste over time.
- Grease and buildup — years of accumulation narrowing the line.
