The kitchen sink is clogged, probably by food. No garbage disposal. Dual sink. It's been slow-draining for a while now, and recently it got worse, and now it's just terrible.
I tried vinegar and baking soda, since that foams up nice in the pipes, followed by hot water and all. Not much help. I checked the trap, it had some food in there but not enough for a clog. Cleaned it out. Tried more vinegar and baking soda. Then I went and got a snake. The water flows fine until it hits the clean-out port. That's where it all pools up. I got the snake down pretty far and found nothing, but now I can't get it more than two feet.
The landlord is being lame and not answering, but either way, if possible I'd like to take care of this myself before I have to go find the dude and make him fix it. Is there something I can do that doesn't involve drain-cleaning chemicals, or can someone talk about how to snake something properly? I'm immensely frustrated by this.
