Clogged Drain Won't Clear
A sink, tub, or floor drain is backed up and won't drain despite basic efforts.
Clogged Drain Won't Clear: A clogged drain that won't clear with a plunger typically has a deep blockage from grease buildup, tree root intrusion, or a collapsed pipe. Professional drain cleaning costs $125–$500. For recurring clogs, a camera inspection ($150–$300) identifies the root cause and prevents repeated service calls.
What Causes This?
Grease Buildup
Kitchen drains accumulate grease, soap, and food debris over time. The grease hardens inside pipes, narrowing the flow path until it blocks completely.
Hair and Soap Scum
Bathroom drains collect hair, soap residue, and body oils. These form tough clogs that plungers can't always reach.
Tree Root Intrusion
Tree roots seek moisture and grow into sewer line joints. Common in older Sacramento homes with clay or cast-iron sewer pipes and mature landscaping.
Collapsed or Offset Pipe
Older pipes can crack, collapse, or shift due to ground movement, Sacramento's clay soil, or age. This creates a permanent blockage point.
Foreign Object
Kids' toys, hygiene products, excessive toilet paper, or 'flushable' wipes (which aren't really flushable) lodged in the pipe.
Can It Wait?
A single slow drain is inconvenient but not urgent. Multiple slow drains or sewage backing up into the home is urgent and may indicate a main sewer line problem.
What Does It Cost?
| Item | Cost Range |
|---|---|
| Single Drain Clearing | $125–$250 |
| Main Line Snaking | $200–$400 |
| Hydro-Jetting | $300–$500 |
| Camera Inspection | $150–$300 |
| Root Cutting | $200–$500 |
| Pipe Replacement (if collapsed) | $1,000–$5,000+ |
Repair vs. Replace
Repair
Clear if: this is a first-time clog or the pipe material is in good condition. Hydro-jetting effectively removes grease and roots.
Replace
Replace if: camera inspection reveals a collapsed, cracked, or bellied pipe. Trenchless pipe lining ($3,000–$8,000) is less disruptive than traditional dig-and-replace.
Rule of thumb: If you're calling for the same clogged drain 3+ times per year, invest in a camera inspection to find the root cause rather than repeatedly clearing symptoms.

Why does my drain keep clogging?
Recurring clogs usually indicate a deeper issue: grease buildup in the line, tree root intrusion, or a structural problem with the pipe. A camera inspection ($150–$300) can identify the exact cause and determine whether you need hydro-jetting, root cutting, or pipe repair.
Is Drano safe for my pipes?
Chemical drain cleaners like Drano can damage older pipes (especially PVC glue joints and metal pipes) and rarely fix deep clogs. They're also hazardous if a plumber needs to work on the line afterward. A plunger or drain snake is safer and more effective.
What is hydro-jetting?
Hydro-jetting uses high-pressure water (3,000–4,000 PSI) to scour the inside of pipes, removing grease, roots, and mineral buildup. It's the most thorough cleaning method and costs $300–$500. Unlike snaking, it cleans the full pipe diameter, not just punches through the clog.
