Is This a Sewer Backup?
A sewer backup means your main sewer line is so blocked that wastewater has nowhere to go but back up through your drains — into your basement, bathroom, kitchen, or wherever the lowest drain happens to be. It’s a biohazard. It causes water damage that escalates by the minute. It needs immediate response, not a ‘call us tomorrow’ delay.
🚨 STOP = active sewer backup. Stop using water. Call us immediately. ⚠ = warning sign. Backup likely if not addressed quickly.
| Sign | Symptom | What It Means |
|---|---|---|
| 🚨 STOP | Sewage coming up through floor drains, tubs, or showers | Active sewer backup. STOP using water. Call immediately. |
| 🚨 STOP | Black or brown water rising from any drain | Wastewater is reversing direction. The line is severely blocked downstream. |
| 🚨 STOP | Strong sewage smell from any drain | Untreated sewage is escaping the system. Health hazard. |
| 🚨 STOP | Water comes up in tub when toilet flushes | Classic backup — main line so blocked that toilet water has nowhere to go but up through tub. |
| 🚨 STOP | Multiple drains overflowing simultaneously | Whole-home sewer failure. Call 24/7 dispatch — biohazard. |
| ⚠ | Gurgling drains + sewage odor + slow drains | Pre-backup warning. Backup likely within hours/days if not addressed. |
| ⚠ | Recent heavy rain + drain backup | Possible city sewer main overflow or yard drain saturation. Different cause than a typical blockage. |
Bottom line: if anything is coming UP through any drain, you have a sewer backup. Call (323) 742-4665 right now.
🚨 STOP — Do These 6 Things Right Now
While we’re on the way, these steps minimize damage, protect your family from biohazard exposure, and preserve your insurance claim. Most of these take 5 minutes total.
| 1 | STOP using water | Every drain, every flush, every faucet. More water in the system = worse backup. Tell every person in the house immediately. Turn off appliances that use water (washing machine, dishwasher). |
|---|---|---|
| 2 | Don't touch the sewage | Raw sewage is a biohazard. Bacteria, viruses, parasites. Don't try to mop it up, don't move soiled items barehanded, don't walk through it. Keep pets and children out of affected areas. |
| 3 | Move valuables out | Lift anything you can off the floor in affected areas. Get electronics, paperwork, photos, and clothing away from sewage exposure. If you can move furniture safely without touching contamination, do it. |
| 4 | Open windows for ventilation | Sewage fumes contain hydrogen sulfide and methane. Open windows in affected areas. Don't use ceiling fans (spreads contamination). Run a window-mounted fan blowing OUT if you have one. |
| 5 | Take photos and video | Document EVERYTHING before cleanup begins. Multiple angles. Every affected area. Timestamps. Insurance adjusters require this. Photo the source if visible (e.g., overflow point at a specific drain). |
| 6 | Call Maverick | We dispatch immediately for active backups — typically 60-90 minute response. Stay out of the affected areas until we arrive. |
Don’t try to clear the backup yourself with a snake or chemicals — both can make the contamination worse. Just stop the water, document, ventilate, and stay clear until we arrive.
What Causes Sewer Backups in LA Homes?
Sewer backups don’t happen randomly. After 15+ years of LA emergency response, here are the causes we encounter most often:
Cause list
- Tree root intrusion — #1 cause in LA homes with mature trees. Roots grow through cracks in aging clay or cast iron sewer lines and eventually completely block flow.
- “Flushable” wipes accumulation — the modern menace. Wipes don’t break down. They accumulate over months, combine with grease, and eventually create complete blockages.
- Pipe collapses in aging lines — pre-1980 LA homes with original clay or cast iron sewer laterals reach end-of-life. Collapses create immediate, severe backups.
- Heavy grease and food buildup — usually from kitchen drains over years.
- Foreign objects — toys, sanitary products, paper towels, anything that isn’t toilet paper.
- City sewer main issues — sometimes the problem is downstream of your property. We diagnose this and can liaise with the city.
- Storm runoff overwhelming the system — during heavy LA rains, especially in older neighborhoods with combined storm/sewer systems.
How Maverick Responds to Active Sewer Backups
Step 1 — Emergency Dispatch
Call (323) 742-4665 — a real person answers 24/7. We gather symptoms, your address, and confirm whether this is active backup (top priority) vs slow drains (regular priority). Truck dispatched immediately for active backups. 60-90 minute typical arrival.
Step 2 — On-Site Assessment + Documentation
Technician arrives in marked Maverick truck with main-line snake, hydro jet, and HD camera. Before clearing, we photograph the affected areas for your insurance documentation. We assess the access point and discuss the clearing approach with you.
Step 3 — Clear the Backup
Most active backups clear with motorized main-line snake in 60-90 minutes. Severe cases require hydro jetting at 2,500-4,000 PSI to scrub the line. We focus on stopping the backup quickly so cleanup can begin.
Step 4 — Camera Verification + Documentation Package
After clearing, we run the HD camera through the line to verify flow AND check pipe condition. You receive: digital camera footage, photos of the backup, written report with timestamps, and recommendations — everything formatted for insurance claims.
INSURANCE CLAIM SUPPORT
Documentation Built for Your Insurance Claim
Standard homeowners insurance often doesn’t cover sewer backup unless you have specific sewer backup coverage as an add-on. Check your policy. Regardless of coverage, we document every backup we respond to: photos before clearing, HD camera footage of the line condition, written report with timestamps, identification of the cause. The documentation is yours to use however you need it.
What's included in documentation
- Photos of affected areas (multiple angles)
- HD video of sewer line condition before AND after clearing
- Written report identifying the cause (root intrusion, blockage, pipe damage)
- Timestamps for arrival, work, and completion
- Recommendations for any follow-up repair needed
When a Backup Means You Need Sewer Repair
Many sewer backups have a deeper cause — a damaged sewer line that allowed roots in or developed cracks that grew over time. Once we clear the active backup, the camera tells us whether the pipe is healthy or damaged. Healthy pipe = clearing solved it; healthy line going forward. Damaged pipe = repair needed to prevent recurrence.
If camera inspection reveals pipe damage, we provide a written quote for the repair separately. You decide whether to proceed with us, get a second opinion, or schedule for later. We never pressure on-site decisions — you have all the information.

Sewer Backup FAQs
What should I do if sewage is backing up into my home?
First, stop using all water in the home — every drain, every flush, every faucet. The more water enters the system, the worse the backup gets. Don’t touch the sewage (it’s a biohazard). Move valuables and pets away from affected areas. Take photos for insurance. Then call (323) 742-4665 — we typically respond within 60-90 minutes.
Is sewer backup dangerous to my health?
Yes. Raw sewage contains bacteria, viruses, parasites, and chemicals that cause serious illness. Don’t touch it, don’t breathe the fumes, don’t try to clean it yourself without proper protective equipment. Keep children and pets away from affected areas. Open windows for ventilation. After we clear the backup, professional sanitization is typically required for affected surfaces.
How long does sewer backup cleanup take?
Clearing the backup itself typically takes 60 to 90 minutes from our arrival. Sewage cleanup is a separate process and depends on how much sewage spread, what materials were affected, and whether walls or flooring need replacement. We focus on clearing the backup quickly so cleanup can begin. Larger contamination usually requires a specialized sewage remediation contractor.
Will my insurance cover sewer backup?
Standard homeowners insurance often does NOT cover sewer backup damage unless you have specific sewer backup coverage as an add-on. Many insurers offer this for a small additional premium each year. Check your policy. We document the backup with photos, video, and written reports formatted for insurance claims regardless of whether your coverage applies — the documentation is yours to use.
What causes a sewer backup?
Sewer backups happen when the main sewer line is so blocked that wastewater has nowhere to go but back up into your home. Common causes: tree root intrusion through cracked pipes, accumulated grease and debris, foreign objects (wipes, sanitary products), pipe collapses in aging clay or cast iron lines, city sewer main issues, or storm runoff overwhelming the system during heavy LA rains.
Can I clean sewage backup myself?
Small amounts on hard surfaces — possibly, with proper PPE (rubber gloves, mask, eye protection) and proper disinfectant. Anything beyond a small spill should be handled by professional sewage remediation specialists. Saturated carpet, drywall, or furniture typically can’t be safely cleaned and must be removed and replaced. Health risk isn’t worth the cost savings.
How do I prevent another sewer backup?
Three preventive actions help: 1) Annual professional sewer maintenance — camera inspection plus hydro jetting if needed catches issues before they cause backups. 2) Don’t flush wipes (even ‘flushable’), feminine products, or grease. 3) Address recurring drain issues immediately — recurring clogs often signal the early stages of a future backup. Older LA homes especially benefit from preventive maintenance.
What's the difference between a sewer backup and a clog?ake to clear a main line clog?
A clog is a blockage. A backup is what happens when the blockage is severe enough that wastewater reverses direction and comes up through your drains. All backups start as clogs, but not all clogs become backups. If you’re seeing sewage coming UP through any drain, you have a backup — call immediately. If a drain is slow but nothing is coming up, you have a clog.
