Grease, oil & food residue
Poured down warm, it cools and sticks. Layers build until the opening is a fraction of the pipe's diameter.
Education
Why sewer drains clog
Most sewer drain blockages build slowly. Knowing the causes makes the warning signs easier to catch.
Common Causes
What actually blocks the line
Soap scum & hair
Bath and laundry lines collect a film that catches hair and lint, forming a mat that traps everything after it.
Wipes & non-flushable items
So-called flushable wipes, paper towels, and hygiene products don't break down and snag on any imperfection in the line.
Scale, sludge & debris
Mineral scale roughens the pipe wall and soft sludge settles in low spots, both slowing flow long before a full blockage.
Tree roots & external intrusion
Roots seek moisture and can enter through joints or cracks, then catch passing waste and grow denser over time.
Aging or damaged drain lines
Older pipe can sag, offset at joints, or lose interior smoothness, giving material a place to collect.
Heavy use & recurring buildup
Large households, rentals, and food-service kitchens push far more material through the same line every day.
Warning Signs
Catch it before the backup
- Slow drains in one or more fixtures
- Gurgling from drains or toilets
- Bad odors near drains or a cleanout
- Water backing up into tubs or floor drains
- Clogs that return again and again
- Multiple fixtures acting up at the same time
Schedule drain cleaning or a camera inspection
If the drain is warning you, don't wait for the backup. We'll clear the line and can show you what's inside.
