Clogged washer drain pipe
When we run the washing machine, the drain backs up and water overflows. It only happens during the cycle where it pumps the water out. I snaked the pipe maybe 20 feet. It didn't seem to run into anything or did it have anything on the end of the snake. I used two bottles of professional strength liquid plumber foaming snake. It still is backing up, any suggestions?
Also (a little more info (I noticed a lot of people don't give enough info at the beginning)) our house is about 50 years old, has a basement (where the washer and drying are), and the drain pipe is 1 1/2" pvc. The drain pipe connects to one of two main drain pipes leading to the ground. Also it shares a main drain with the kitchen sink and dishwasher (which is newly updated.)
