problem drain clog - advanced

17 years ago

I have a customer with this issue: kitchen waste is again backing up in basement bathroom lavatory. Basement toilet flushes fine. Presumably this would mean the clog is in the smaller line, which I snaked two months ago, and all was well. And now it's back. How would you handle this?

Last time I was there, I used 25' of a 1/4 hand snake accessed under the bsmt. lavatory. That was as big as I could safely get past the bends into the floor lateral, and there's no clean-out. The toilet was previously pulled by rooter guys, but I don't see that being the solution, since presumably it's just downstream of the obstruction.

The roof is not an option (for me, anyway) since it requires a 40' ladder on a fairly steep slate roof. While I do have the ladder, the stack is out of reach from the edge.

Today I'm thinking of using a 3/8 hand snake (either 25' or 50'), entering through the kitchen above, which maybe I should have done last time. What do you think? Any other ideas? (Sulfuric acid time? Foaming drain cleaner time??)
