Clogged drains and sewer problems are among the most common—and most frustrating—plumbing issues South Florida homeowners face. From slow-draining sinks to complete sewer backups, these problems disrupt daily life and can cause significant property damage if not addressed properly.
This comprehensive guide covers everything you need to know about drain cleaning and sewer services, helping you understand when to tackle issues yourself and when to call a professional.
Understanding Your Drain System
Before diving into solutions, understanding how your drain system works helps you prevent problems and communicate effectively with plumbers.
How Home Drains Work
Your drain system operates on gravity and proper venting:
Fixture drains: Individual drains from sinks, tubs, and showers connect to branch drain lines
Branch lines: Horizontal pipes that collect from multiple fixtures and carry waste to the main stack
Main stack: Vertical pipe that connects all branch lines and vents through the roof
Main sewer line: Large horizontal pipe carrying all waste from your home to the city sewer or septic system
Vent pipes: Allow air into the system, preventing vacuum that would slow drainage
Common Drain Sizes
Different fixtures use different drain sizes:
- Bathroom sinks: 1.25-1.5 inches
- Kitchen sinks: 1.5-2 inches
- Showers and tubs: 1.5-2 inches
- Toilets: 3-4 inches
- Main sewer line: 4-6 inches
Knowing these sizes helps you understand why some clogs are easier to clear than others.
Common Causes of Drain Clogs
Understanding what causes clogs helps you prevent them.
Bathroom Drain Culprits
Hair: The number one cause of bathroom clogs, hair tangles and catches other debris
Soap scum: Combines with hair and minerals to create stubborn blockages
Personal care products: Cotton swabs, dental floss, and feminine products shouldn't go down drains
Medication: Pills and capsules can contribute to buildup
"Flushable" wipes: Despite marketing, these don't break down like toilet paper
Kitchen Drain Problems
Grease and oil: Solidifies in pipes, catching other debris
Food particles: Even with disposals, some foods shouldn't go down drains
Coffee grounds: Accumulate and create dense clogs
Pasta and rice: Expand with water and stick to pipes
Eggshells: Stick to pipe walls and catch other debris
Main Sewer Line Issues
Tree roots: The most common cause of main line blockages in Miami
Bellied pipe: Sections that have sunk create collection points
Corrosion/collapse: Aging pipes deteriorate and block flow
Foreign objects: Items flushed or washed down that shouldn't be
Scale buildup: Mineral deposits from hard water
Warning Signs of Drain Problems
Recognizing early warning signs prevents major problems.
Signs Requiring Attention
Slow drains: Water taking longer than normal to drain
Gurgling sounds: Air bubbles indicate venting or blockage issues
Bad odors: Sewer smells suggest buildup or blockage

Frequent clogs: Recurring problems indicate deeper issues
Signs Requiring Immediate Action
Multiple slow drains: Suggests main line problem
Sewage backup: Raw sewage coming up through drains
Water around floor drains: Indicates main line backup
Toilets won't flush: Complete blockage present
Sewage smell in yard: Main line may be broken
DIY Drain Cleaning Methods
Many minor clogs can be handled without professional help.
The Plunger
For sink and tub drains:
- Remove stopper or strainer
- Cover overflow hole with wet rag
- Fill sink with 2-3 inches of water
- Use cup plunger with firm, consistent plunges
- Check if water drains freely
For toilets:
- Use a flange (toilet) plunger
- Ensure the flange is extended
- Create seal over drain opening
- Push and pull firmly 15-20 times
- Test flush
Drain Snaking
For clogs beyond the plunger's reach:
- Feed snake into drain opening
- Turn handle clockwise while pushing
- When resistance is met, continue turning to break through
- Pull back slowly, removing debris
- Repeat if necessary
- Flush with hot water
Natural Cleaning Solutions
Baking soda and vinegar:
- Pour 1/2 cup baking soda down drain
- Follow with 1/2 cup white vinegar
- Cover drain and wait 15-30 minutes
- Flush with hot water
Boiling water: Effective for grease and soap buildup
- Pour slowly in 2-3 stages
- Allow water to work between pours
- Do NOT use on PVC pipes (can soften joints)

Frequently Asked Questions
How often should drains be professionally cleaned?
For most homes, annual preventive cleaning is sufficient. If you have trees near your sewer line, every 6-12 months is recommended. Commercial properties typically need monthly service.
Is hydro jetting safe for old pipes?
Hydro jetting is adjustable and can be safely used on most pipes. However, a camera inspection first is recommended for older homes to assess pipe condition. Very deteriorated pipes may not be candidates for high-pressure cleaning.
Why do my drains smell bad?
Drain odors usually come from buildup in the pipes, dry P-traps (run water in unused drains), or vent problems. Professional cleaning and inspection can identify and resolve the source.
Can I use chemical drain cleaners occasionally?
We recommend against chemical cleaners entirely. They're hard on pipes, dangerous to handle, and often don't solve the underlying problem. Natural methods or professional service are safer and more effective.
What's the difference between a drain snake and hydro jetting?
Snaking punches through clogs but leaves residue on pipe walls. Hydro jetting scours the entire pipe interior, removing all buildup. Hydro jetting is more thorough but not always necessary for simple clogs.
