Short answer
Drains keep clogging when the buildup was only punched through instead of removed, when something structural catches waste (roots, a sag or a broken pipe), or when the same materials keep going down the drain. Repeat clogs in one fixture are usually buildup; repeat clogs in several fixtures point to the main line.
One drain or many?
Start by noticing which drains are slow. One sink or tub on its own is almost always a local clog. Two or more fixtures, especially the lowest drains in the house, mean the main line. That single observation decides who to call and what tool is needed.
The usual culprits by room
- Kitchen: grease, starches, coffee grounds, disposal overuse
- Bathroom sinks: hair, toothpaste, soap film
- Showers and tubs: hair and soap
- Toilets: wipes (even 'flushable'), paper towels, too much paper at once
- Main line: all of the above plus roots in older pipe
Why clearing doesn't always last
A cable machine opens a path through a clog. If grease coats the pipe walls, the path closes again within weeks. Jetting removes that coating. If a camera finds roots or a sag, repair is the only lasting fix.
Habits that prevent repeat clogs
- Wipe greasy pans into the trash before washing
- Use strainers in sinks and tubs
- Flush only toilet paper
- Run plenty of water with the disposal
- Skip chemical drain cleaners; they don't remove grease or roots
Fixture clog or main line problem?
| Pattern | Points to | Next step |
|---|---|---|
| Same sink clogs every few months | Buildup in that branch line | Professional cleaning, then better habits |
| Different fixtures take turns clogging | Main line restriction | Main line cleaning and camera inspection |
| Clogs after heavy rain | Root intrusion or groundwater entering the lateral | Camera inspection |
| Clogs began after a remodel | Drain slope or venting problem | Have the new drain run checked |
Why snaking alone often isn't enough
A cable punches a hole through a clog and restores flow, but grease, scale or roots stay on the pipe wall and catch the next round of waste. That's why the clog returns in a few weeks or months. Jetting the line removes the coating; a camera inspection shows whether a physical defect such as a sag or broken joint keeps trapping waste. Fixing the cause costs more once but ends the cycle of repeat service calls.

Frequently asked questions
Do enzyme drain cleaners work?
They can slow organic buildup with regular use but won't clear an existing clog or roots.
How often should drains be professionally cleaned?
Most homes don't need scheduled cleaning. A line that clogs repeatedly should be inspected rather than cleaned on a schedule.
