Hi folks - the ABS drainpipe that comes out behind my washer spouts water when the washer drains into it. This has occurred since we moved into our new home. I thought that the problem was that the flexible black drainage hose from the back of the washer (the drain hose which has been there since I bought the Maytag washer over a decade ago) was in at a bad angle causing the water to splash back out but adjusting the hose didn't help. It is almost as though the water comes out at such a high rate that an air pocket in the drain pipe causes the water to back up the pipe and into the wall (then leaking through the floor underneath).
Has anyone seen this problem before and, if so, any tips on fixing it? Thanks!
