I'm no fan of pouring harsh chemicals down your drainage systen. Especially if you have a septic tank. Besides, they only work in TV commercials.
Your 1/4" snake is only effective on small drain pipes.
Rent a sewer machine and snake from the kitchen roof vent. Put out enough cable to reach the base of the stack and about 25' more. Cycle the washer to both test and flush any debris that may remain. good luck, Tom
