I live in a multi story apartment building on the first floor. My washer/dryer are stacked atop each other in a small closet. I've noticed puddles of water on the ground before but did not know the source of where it was coming from.
Recently, I was at home when I heard a noise coming from the closet. I slid out the washer/dryer and saw a large amount of water on the ground with lots of soap suds. I looked inside the stand pipe and saw soap suds inside the pipe. Based upon the soap on the floor and the soap inside the standpipe, I believe the pipe was overflowing.
I haven't ran my washer in at least two weeks prior to the incident. I'm not sure why the pipe is overflowing. There are two apartments above mine with the same floor plan and I assume we all share some type of piping for our washing machines.
Any suggestions on what to do? Could this be a clogged pipe somewhere that needs to be snaked? I contacted management who sent out a plumbing company. They didn't do much except peek around a little and say they didn't observe any leaks. I've only noticed the puddles of water about 3 times in the last year or so.
Thank you!
