About two days ago my kitchen sink started backing up. I have a duel-y sink, one side having a garbage disposal and the other regular with a very small drain (too small for a snake I've come to find out). I tried two bottles of draino which didn't help. Today I bought a snake that attached to a power drill and snaked it 20' into the pipe. Once again, it didn't help; however, nothing else in my apartment is clogging (shower, toilet, kitchen sink). I have no money to afford a plumber and clogged drains aren't repaired under my lease. Any suggestions??
