well I couldn't get into the sewer for any help so I decided to try sewer's aid!
actually I put mine in the tub (12X18) went to work, came home 5 hrs later and drained, dried, and "played it". you know, hold by each end and bend back and forth fast, made a nice noise and felt pretty flexible. I didn't think to try it before tho! LOL if nothing else it did get the lint off.
