Washing machine drain plugged?

[bertschb]

I just ran our washing machine for the first time and when it started the drain cycle, water started pouring out of the front of the RV (318RST). The drain pipe is plugged. Has anybody else had this happen? What could cause the washing machine drain pipe to be plugged? Help!!!

On my previous SOB the washer drained straight to the dump tube. If it wasn't connected to sewer, it would back up

I'm connected to the sewer with the gray valves open.

Ours didn't have a trap, it had one of those duckbill things which was installed upside down. We bought that trailer from CW and picked it up in Lowell, AR. They assured us they tried the washer. It flooded our bathroom first time we ran it

Can you get a small plumbing snake from your local home improvement store and run it down the pipe?

Do they have a trap or the duckbill thing? I'm not familiar with the Reflections

OK, here's the update. I called GD support and he said that drain line has some kind of trap as others have suggested. He said when they pressurized the lines it may have flipped it backwards. Anyway, to fix it I ran a coax cable down the pipe (that's all I had available). The valve is about 3' down the line. I kind of crammed the coax cable up and down several times and felt something give way and the water flowed out. I just started a new load in the washer. We'll see what happens. BTW, if anybody has a picture of what this valve may look like, please post it as that might be helpful to others.

Word to the wise - check your drain line before you use your washing machine for the first time!!!

Mine was white PVC, about 7" long. Had slip nuts on both ends. Sorry I don't have a picture

Thanks for posting that LC. Very helpful. Now that I know what kind of valve that is, I found this:
