A sewer line problem is one of the most disruptive—and costly—issues a homeowner can face. Unfortunately, many people don’t realize they have a failing sewer line until it’s too late. As a trusted plumbing company serving Sunnyvale and the surrounding South Bay Area, we’ve seen it all—from minor clogs that escalated into full-blown backups, to collapsed lines that could have been repaired earlier with a simple trenchless solution.
At #1 Honest Plumber Inc., we’re here to help you avoid disaster by recognizing the early signs of sewer trouble. Below, we break down the top 10 warning signs your sewer line may need immediate professional attention, what causes them, and how we fix the problem fast.
1. Multiple Slow Drains or Backups
If one drain is slow, it could be a local blockage in that fixture. But if multiple drains throughout your home are slow—or backing up—that’s a red flag pointing to a main sewer line issue. Toilets, showers, and sinks may all struggle to drain properly. You might even notice water backing up into the tub when flushing the toilet. This isn’t just a nuisance—it’s a sign of a partial or full sewer line obstruction.
Common Causes: Root intrusion, collapsed pipe, grease buildup, or foreign objects.
What to Do: Call for a sewer camera inspection immediately to identify the root cause.
2. Frequent Toilet Clogs (Despite Proper Use)
Toilet issues are common—but repeated clogging in one or more toilets (especially if you’re not flushing anything unusual) is a major red flag. If your plunger is working overtime, it’s time to investigate further.
What We Check: We look for line bellies, improper pitch, and root intrusion—all common in older South Bay homes.
Solution: Hydro jetting for soft clogs, or trenchless sewer repair if damage is more severe.
3. Sewer Smells in the Home or Yard
That unmistakable sewage odor isn’t something to ignore. If your home or yard smells like rotten eggs, raw sewage, or sulfur, it’s likely that gas is escaping from a crack, break, or faulty vent in your plumbing or sewer line.
Risks: Health hazards from methane gas and water contamination.
Repair: Depending on the location, we can seal vent leaks or use trenchless technology to reline the pipe.
4. Patches of Extra-Lush Grass
Noticed one section of your lawn growing faster and greener than the rest? That may not be a landscaping miracle—it could be a leaking sewer line acting like an underground fertilizer.
Why It Happens: Leaking sewage adds nutrients to the soil, but also creates unhealthy bacteria risks.
Next Step: We perform a video inspection to confirm leaks and determine the extent of damage.
5. Yard or Basement Flooding
Any standing water in your yard—especially near where your sewer line runs—is cause for concern. In homes with basements or crawl spaces, sewage leaks can cause water to pool inside, resulting in mold growth and structural damage.
Warning: This is often the final stage of an unresolved sewer line issue.
Emergency Service: Call immediately for containment, cleanup, and pipe replacement.
6. Gurgling Sounds in Drains or Toilets
When a drain or toilet makes a bubbling or gurgling noise, it means air is getting trapped in your plumbing—often due to a blockage. You may notice these sounds when using a different fixture in the house (like the tub gurgling when the dishwasher runs).
Cause: Restricted sewer venting or mainline clogs.
Inspection: We use real-time camera feeds to identify airflow disruption points.
7. Toilet Water Level Changes
Is your toilet bowl water too high one day and unusually low the next? Fluctuating levels indicate inconsistent pressure in your sewer line, usually from a clog or partial blockage. This may be an early-stage sign before complete backup occurs.
Don’t Wait: The longer it’s ignored, the worse the blockage becomes.
8. Cracks in the Foundation or Driveway
When a sewer line leaks underground for an extended period, it erodes the soil around your home’s foundation. This can cause cracking in concrete, brick, or tile flooring—even your driveway or patio.
How to Tell: Cracks that appear suddenly and continue to widen over time.
Repair Approach: We use trenchless pipe bursting to replace the damaged line with minimal excavation.
9. Increased Pest Activity
Rodents and insects are drawn to sewage leaks. If you’re suddenly seeing more bugs or vermin around your property (especially in the yard or crawl space), your sewer system may be compromised.
What We Find: Rats entering through damaged vent stacks, cockroaches drawn to moist environments.
Fix: Repairing pipe entry points and ensuring complete pipe sealing.
10. Unexplained Mold or Water Damage
Sewer leaks inside walls or under flooring can create humid, hidden conditions perfect for mold growth. If you see bubbling paint, warping walls, or a musty smell near bathrooms or the kitchen, a hidden leak may be to blame.
Common in: Older homes with cast iron or clay pipes.
Detection: Our leak detection tools pinpoint exact pipe failure zones.
