My kitchen sink has a garbage disposal, and its drain crosses the entire house within the height of the first floor joists. With 9 1/2" joists, that's at most 7" drop over 23', or a hair over the minimum 1/4" per foot slope. However, I've had clogs in the past, and I'm guessing the slope isn't constant (the basement ceiling is plastered so I can't check).
I've stopped running eggshells and onion peels down the disposal, but I'm still worried about clogs, and I'm thinking that once the drain is blocked it'll be a lot harder to deal with (and a "have to deal with it right now" situation to boot).
- Buy/rent an auger and clean the drain out every few years
- Hire a service to do the same
- Fill the sink with hot water and then run the disposal to rapidly drain it and clean things out
- Don't worry about it until (and unless) it fails.
What's my best bet?
