Washing Machine Overflowing-How to fix?
We live in a 1900 farmhouse where the washer and kitchen sink drain goes into the side yard instead of our septic tank. During the spin cycle, the washer water sometimes backs up into the kitchen sink. Lately, the washer has overflowed several times and water comes out of the standpipe. The water seems to flow steady for about half the spin cycle any I can see it inching up to the top of the standpipe. Then, water goes on down the pipe out of sight. Then it quickly fills back up and overflows.
The plumbing for the washer is as follows: 2" vertical pipe from back of washer through floor (about 3' long), then pea trap in crawl space under house, 2" pipe runs 8-10' horizontally, kitchen sink y'd into drain line, 2" pipe continues to run underground for about 100-150 feet then drains out into the yard.
When washing clothes, there is almost always a bad odor and we noticed that the drain tube going from the washer into the vertical standpipe had crud in it so we changed it and put a new one on. Maybe that will stop the odor. We'll see after we get the overflow problem fixed.
Got any suggestions on what we need to do to repair this? Thanks,
