I live in a house built in 1960 something. The washing machine is on the enclosed back porch where washer/dryer hook-ups are. When I do a load of laundry, the water backs up into my tub. Seemed to be OK because it always drained quickly from tub. Now it is clogging, and the bottom of the toilet is leaking water, (where the toilet bolts to the floor),also bubbles come up in toilet bowl . I have cleaned debris from the tub drain with a pronged device that cleared a gob of hair out and it's OK for a few weeks, but I never had the toilet leak until a few days ago. The floor of the porch is about 8 inches lower than the tub. I think I should snake the drains but am unsure where to start. I appreciate any help. Thanks
