A sewer backup is one of those plumbing problems that doesn’t give you the luxury of waiting until Monday. If sewage is coming up through your floor drain, shower, or toilet in your Del Rey home, it means wastewater has nowhere to go — and it’s reversing direction back into your living space.
Del Rey sits in a low-lying pocket of the Westside between Playa Vista and Culver City, just south of Ballona Creek. The neighborhood’s proximity to the creek and relatively flat elevation means the soil here holds more moisture than higher-ground areas, and that creates ideal conditions for tree root intrusion into older clay sewer laterals. Many homes in Del Rey were built in the 1950s and 60s, and plenty of them still have their original sewer lines running from the house to the city main.
Warning Signs That a Backup Is Coming
Most sewer backups don’t happen without warning. If you’ve noticed any of these over the past few weeks, your sewer lateral is probably telling you something:
Your toilets gurgle when you run the washing machine. Multiple drains in the house are slow at the same time. There’s a sewage smell coming from your yard or near your cleanout cap. You’re seeing dark green patches in the lawn above your sewer line — that’s leaking wastewater fertilizing the grass from below.
When a single drain is slow, it’s usually a localized clog. When multiple drains act up together, the blockage is in the main sewer line itself.
What Causes Sewer Backups in Del Rey
Tree roots are the number one cause. Roots seek moisture, and a hairline crack in a clay or cast iron pipe is all the invitation they need. Once inside, they expand and catch everything flowing through the line — grease, paper, debris — until the pipe is fully blocked.
The second most common cause is grease accumulation. Kitchen grease poured down the drain doesn’t stay liquid — it cools, hardens, and coats the inside of the pipe over time. The Los Angeles Bureau of Sanitation has been running public education campaigns on grease disposal for years because it’s one of the top contributors to sewer blockages citywide.
What We Do When You Call
When we arrive at a Del Rey home with an active sewer backup, the first step is always a sewer camera inspection to see exactly what’s causing the blockage and where it is. No guessing, no exploratory digging. If the clog is from roots or buildup, hydrojetting will usually clear it. If the pipe is cracked, collapsed, or badly deteriorated, we’ll talk you through your options for sewer line repair or replacement — including trenchless methods that don’t require tearing up your yard.
We’ve handled hundreds of sewer backups across the Westside, including in Mar Vista and Westchester. We know the soil, the pipe materials, and the common failure points in this part of LA.
Don’t Wait on This One
A sewer backup isn’t a “schedule it for next week” problem. Standing sewage is a health hazard, and every hour of delay increases the risk of damage to flooring, drywall, and personal property. Call New Pro Plumbing at (310) 663-7666 any time of day or night. We offer 24/7 emergency service and we’re less than 10 minutes from Del Rey.
