Washing Machine Drain Problems
by Sherm Turner
I have a problem. When the washer spins, the water backs up into kitchen sink. Both run in 1 1/2" pipe to a 1 1/2" copper "y fitting" and then to drain stack 10 or so feet away. I have tried a snake with no clog found. I used the snake on vent line and didn't find anything. What could cause this back up? The water needs to travel back up 1 1/2" from "y fitting" to sink about 10 feet from crawl space. Do I need to move washer line to larger drain like toilet (4") drain line?
The 1 1/2" piping and 1 1/2" size trap should be at least 2" or larger with a 36" stand pipe, 2 or 3 inches in size. You're simply trying to push too much water through too small a pipe.
