Washer Drain

[cman]

I have a 2005 3670RL We are think about installing a washer & drier
in it . People said the drain for the washer dump in the black tank.

I have a washer/dryer in my 3670 and the waste water goes into the grey water tank. By-the-way, always make sure the dump valve is open before that washer hits the spin/drain cycle or you may find geysers in places you never intended.

Some have the W/D drain in the grey tank, some in the black tank. Mine happens to be to the black tank. Personally I feel like the grey tank would be the proper of the two. It would be anyone's guess why the differences. I think in my case, the black tank was the closest to make a connection as the potty is just a couple feet from the W/D drain.

When my trailer was new I drained all tanks closed the valves and then started water to the W/D drain, let it run a few minutes and then opened the valves one at a time until I saw water from the drain hose.

Our washer/dryer drains into the gray tank.Like others have said leave your valve open when using the washer/dryer.

We had a lengthy thread on this question a few months ago. We have a label on the wall where the washer/dryer is located that says it drains into the black tank. However, I had the bottom off the trailer because I had a water leak, and heard the washer draining into the gray tank. I don't know where it drains, but we open both tanks on wash day to be safe.

Our 04 3670 drains into the gray tank. You REALLY want to open the drain while using the washer!!!

ours says it's in the black tank but when i install washer dryer i am going to run a water hose into the drain pipe and open the valves one at a time to find out which one it is.

Our early '05 3670RL goes to the grey tank, but later ones could be different, so check to be sure! (Our washer closet is in the bathroom, I think they moved it in later models).

Gbutler, your tank will hold a washer or two worth of water. You could watch until the water starts draining from the washer, then open one valve at a time to see which one contains the wash water. I'd start with empty tanks to make sure. I can tell you from experience (twice) it takes two or three loads before your tank overflows. So, there is time to figure it out. Each holding tank (other than fresh water tank) holds 38 gallons.

we have had no problems with our washer/dryer but i have found that it drains into the black tank so the wife has to empty the tank before she washes
