Grease is the number one cause — it goes down warm and liquid, then cools and solidifies on the pipe wall. After that: food scraps (especially starchy and fibrous ones), coffee grounds, soap scum combined with hard water minerals, and garbage disposal misuse.
Grease Is the Main Problem
Bacon fat, oil, butter, and the grease rinsed off pans all pour easily when warm. A few feet down the line they cool, congeal, and coat the pipe wall. Every subsequent bit of food debris sticks to that layer. This is a slow accumulation that ends abruptly — the drain works fine until the day it does not.
Pour grease into a can and throw it away. Wipe greasy pans with a paper towel before washing. Hot water and dish soap do not solve it; they just move the grease a bit further down the line before it cools.
Food Scraps the Disposal Should Not Get
- Coffee grounds — they clump and settle like sediment
- Pasta, rice, and bread — they keep absorbing water and swelling
- Fibrous vegetables — celery, artichokes, corn husks, and onion skins wrap around disposal blades
- Potato peels — they turn into a starchy paste
- Eggshells and bones — they grind into a gritty sludge that binds with grease
A garbage disposal is not a trash can. It handles incidental scraps, not a plateful.
Hard Water Makes It Worse
Albuquerque’s dissolved calcium and magnesium scale the pipe interior, roughening and narrowing it. Soap and grease then have far more surface to cling to. This is genuinely why local kitchen drains clog faster than the national rule of thumb suggests, and why a water softener reduces drain problems along with protecting your water heater.
What Actually Clears It
Cabling punches a path through. Hydrojetting scours the pipe back to full diameter, removing the grease layer a cable leaves behind — which is why it is the right answer for a kitchen line with repeat clogs. Chemical drain cleaners rarely cut congealed grease and damage older pipe.
