Gray and Black waste pipes

New Owners of Shasta Oasis 18BH. We only had the trailer for a week and we've been spending some time getting to know it better. We came from a pop up so there are some things we are not familiar with, one being the gray and black water tanks and piping. We've been watching videos on dumping the tanks, how they function and how to keep the tanks in good shape. But there is still one thing I can't find an answer to....which pipe is the gray water and which pipe is the black?
I've attached a picture (hope I did it correctly ), is the right pipe normally the black water?

My black pipe is larger in diameter. Also the toilet will sit over the Black tank. That should be a clue. Otherwise get a clear pipe connector for cleaning tanks and you can view the drainage that way.

hard to tell buy the pic. that fitting and hose clamp lead me to believe someone did some after market work to your unit. My unit has a 4 inch line for black and only an 1 1/2 line for grey. Easiest way to prob tell is your floor plan and where your toilet is based on its position to the drain.

Or you will figure out real quick first time at dumpstation. always drain black first so you can clear your line out with the grey water. run the black tank flush or save a little fresh water in your tank to run and clean up after dumping.

Both gray and black will exit that pipe. The gray is likely on one side and the black is the other- see how they "T" together? You control what comes out by pulling the handles on either side of the cap.

If it helps you, when the tanks are empty and clean- run some fresh water into each and then pull the handle to see how it works.

Well if you take that big black cap off and get real close to it and look inside while at the same time pulling the handle on the right......you will know very soon if that is the gray or black tank. Honestly just look at your floorplan. Is your toilet to the left or the right of the main drain.

Many units have decals on the body side that says what handle is for what tank. They are not always correct but mostly are.

As ependydad said, and since you've not used it yet, take the cap off, and pour some water in the sink or shower, go out and pull one of the handles and see if water comes out. If not, pull the other handle and see. You could alternately dump some water down the toilet and accomplish the same.

It's easy to see if you click and expand the picture. The valve on the left is the black tank and the right one is the gray tank.

Both pipes going into the sewer port appear to be the same size.
As do the blade valves themselves.
How'd you come up with that?

geez...such an easy solution, not sure why I didn't think of it. Guess since the trailer is at a storage lot in our community I wasn't thinking about emptying the water on the ground. Soooo... I will be dumping some water in my sink and then pull one of the values to find out which one is the gray water.
Thanks all for the quick replies.

From the layout with your toilet in the rear I would guarantee it's the pipe going to the rear.

I'm on a laptop, I click on the picture twice and it expands to full size. It's easy to tell which pipe/valve is the larger.

I'm on a desktop computer with a 27" monitor. I expanded the pic as much as I could and still can't tell any size difference between the two sides.

Not trying to one up you but I have a 40" monitor here at work and double clicking the photo makes it larger than life. Importing the photo into a quality editing program and even changing brightness and contrast definitions, I see no difference in pipe or blade valve sizes.

I need scrapper's eyes!

Here is the layout of his camper and the top right arrow is where the sewer drain is. So there is no doubt about it that the pipe on the right is the black tank drain.

Guess we'll have to wait for the OP's test!

My bad. Looking at the picture again it looks like you are right. It also looks as though there is a rubber connection clamped onto the pipe which I would think is not a good thing for the black pipe.

The black tank will be directly beneath the toilet. Looking at the outlet in the picture, is the toilet to the left or to the right in your camper. The black tank drain valve will be on that same side of the outlet as the toilet.

black or gray

I look at my screen close and what I thought was the number 2 now looks like a number 4 on the right pipe so I would open it last to check in storage.

I did the "test"...dumped a gallon of water in my kitchen sink, went outside pulled the "gray water" valve and ....a gallon of water came out. I let that drain, closed the valve and opened "black water" valve...nothing.
So...left is "gray", right is "black".
Our first camping trip in the new trailer is end of May, hopefully everything will go well....I've read everything I could find about using, taking care of, and dumping the grey/black water tanks and I've watched way too many videos...some are down right hilarious.
One thing I still have a question about and it seems people handle it in different ways.
After the black water is emptied, I use the gray water to "clean" out the hose BUT how do you clean out the black water tank while you're at the dump station ?
Do I use a bucket full of water and dump into the toilet as I empty the black water?
I don't have a way to clean it out at home so any type of cleaning that I need to do will need to be done at the dump station.
