Laundry standpipe overflow
The standpipe that our washing machine drains into recently started overflowing. It's only a small amount at a time, creating a tiny puddle that runs in front of the machine. It seems to happen during the rinse cycle. There's no noticeable odor or sudsing. Any idea what could be causing this problem?

You are developing a partial clog in your drain line. You need to run a snake down the standpipe and past the trap to clear it. If it persists or gets worse there is a "last resort" fix that I had to use at my place and just passed on a few minutes ago to another asker with the same problem. This is then advice I gave him, "I had the same problem at my house the washer pump discharged with so much force that it sometimes backed up. I cured it by attaching a 2 X 1 1/2" compression fitting on top of the stand pipe and making a water tight connection between the hose and stand pipe. Your trap and stand pipe are 2" aren't they? If your trap and standpipe's 1 1/2" simply purchase a 1 1/2 female X 1 1/2" compression fitting and install that. Good luck, Tom
