Outside Kitchen Drain??

Not a big deal just surprised when my sink backed up so fast. I already have a t and now just need like 20 more feet of Rhino Flex and another clear shut off for that tank and just leave it open when the gray and black are close to the outside kitchen just flows from sink to sewer.

No need for Rhino Flex - or draining onto the ground - (YIKES!..:()
(Depending on location, that *may* result in a citation & fine)

Use a cap with a garden hose fitting on the trlr kitchen drain pipe.

Use one of the (very common) 3" sewer connection elbow (the one that goes into the campground's in-ground sewer drain) *which also has a garden hose connection*.

Note - those usually have a "knock-out" inside the garden hose connection.

Use whatever length of cheap-o garden hose (not white) you need, swap the male fitting to female.
(The sewer drain cap -at the trlr- for the garden hose, and the elbow connection for the garden hose, will both be male)

If you don't want to drain your other tanks, just cap off the 3" connection on the fitting until you want to use it.
Of course, you can leave both connected if you wish.

BTW - my Jayco RK has a separate gray tank for the kitchen, but I usually do the above - - 'cause it's quick, EZ and no big deal..:W

Think they all have there flaws, my issue for sure no deal breaker just an adjustment and fixed, still love my new 5er.

Perhaps it has to do with the height of the top of a gray tank, versus the bottom of an outside sink? Gravity!

Mountaineer is not the only manufacturer to NOT drain the Outside Kitchen in to a tank.

My friend just bought a new Mountaineer and his outside kitchen sink drains directly to the sewer outlet like you described. The only thing we could think of was that it had something to do with the OK being on a slide out. It really isn't a big deal as the water would not be real dirty. Still though, direct draining of grey water does not go over well at some CGs. I guess one could put a 5 gal pail under the outlet.

You could install a twist-on valve at the outlet, open the tank valve, and the waste would be captured. Then dump at a convenient time.

Our friends also have a Mountaineer and the only thing I can figure is that it was done that way to drain into the ground. Most of the things you will put in it are just rinsing glasses, washing your hands, etc.

I don't know, but I thought it was real strange, too.
