Common Sewer Line Problems We Fix ( On a Regular Basis)
Call Charlie PROBLEM SOLVED!
Sewer issues don’t start with a bang; they creep in. One drain slows down.
A weird smell hits the bathroom.
Then, suddenly, all your bathroom drains are non-functioning
And you’re left wondering what went wrong. Here’s what we look for when diagnosing a sewer line repair in San Diego:
Slow Drains, Foul Odors, Gurgling Sounds, Frequent Stoppages, and Exterior wet spots on the ground.
I removed and replaced the plumbing in a kitchen and a bathroom because they were experiencing frequent stoppages in the apartment image to the right.
Slow Drains in Multiple Rooms
A single slow drain may require a quick drain cleaning, but if you’re noticing slow water flow in the shower, kitchen, and bathroom all at once, that’s a more significant issue. It typically points to a blockage or partial collapse in the main sewer line, not just a localized clog. We inspect the entire system to identify and resolve the root cause, not just the symptom.
Foul Odors Inside or Outside the Home
If your home smells like rotten eggs or something is off in the yard, you’re likely dealing with a sewer gas leak. This occurs when cracks or breaks in the line allow gases to escape, particularly in older, corroded cast-iron systems. We locate and repair the source quickly, and if necessary, replace it with clean, corrosion-resistant ABS piping for long-term peace of mind.
Gurgling Toilets and Bubbling Drains
Toilets that gurgle or sinks that bubble are usually signs that air is getting trapped due to blockages in the sewer line. This pressure imbalance can result in partial blockages or inadequate venting. It’s a subtle sign but a big one. We’ll inspect vents, cleanouts, and lateral lines to ensure your system isn’t backing up slowly. If necessary, we can coordinate repairs with a toilet repair service.
Backups in Showers, Tubs, or Toilets
If flushing the toilet causes the bathtub to back up, that’s not normal; that’s an emergency. It usually means the main sewer line is either entirely blocked or severely damaged. We handle these emergency calls 7 days a week. Our crew arrives equipped to clear the line or dig in fast if the pipe is broken. We can also check for related issues during the visit, such as hidden leaks or slab damage.
Wet Spots or Lush Grass in the Yard
If one section of your yard is consistently wet or greener than the rest, and you’re not overwatering it, it could indicate that your underground sewer line is leaking. These leaks can erode soil, cause sinkholes, and even damage your foundation. We’ll inspect the line with a camera, locate the break, and offer options for repair or full replacement using modern, code-compliant repipe solutions.
