Washer dryer hookup

[Ranchhand]

So my 2019 cougar 369BHS has a washer dryer hookup that we don’t use. I winterized a couple of weeks ago and realized last weekend that I forgot to winterize the washer hookup. I got the hot and cold faucets done but I am unsure what the black pipe is in the picture. I assume it is a drain for the washer so it would have a trap and should have some antifreeze dumped down it. Is this correct or is the pipe for something else.

The black pipe is the drain for a washing machine. However, if you have never had a washing machine hooked up, there's no water standing in that line anywhere. Nothing to worry about. You're good.

It's the wash machine drain. Should have a plug in it, not open ended. If in doubt pour a cup of anti freeze down it.

Looks capped to me.

It has a cap on top of the pipe. What do you mean not open ended. I guess another question would be that I have is where does the drain go. I assume to a grey tank.

That means it's capped or plugged not an open pipe.
Yes Chuckster appears to be a cap, all I've had there was a threaded collar with a plug in it, guess they've found a cheaper way.
