2020 292BH Gray tank valve

[Papa22]

We are camping in our 2020 Passport 292BH. I believe the gray and black tank valves are labeled backwards. Can someone that has one confirm which one, front or back valve is the gray tank valve?

You could just drain the tanks, run 5 gals. of water into one, pull the handles and see which one it comes out of???

Our Passport 239ML wasn't labeled at all (and both handles were black). Turned out the black tank valve was to the rear/right of the sewer connection (where the black tank is directly below the commode) and the gray was to the left of the sewer outlet.

I have e a 2020 Laredo 311BH. both handles are exactly the same (a pet peeve). Grey is on left, and black handle is one on right....for my 2020 rig.

Agree with others, a clear 90 degree attachment should let you visually see which is which upon emptying.

My 2020 Passport 2600BH is also the same... grey water on the left and black water on the right... both are labeled on the side of the TT but ironically the labels are no where near where the valve handles are... lol...
Guess Close was good enough... :lol:

Seems like the consensus is gray to the left. Now that at I say that, someone will tell me otherwise on their unit... therefore my CYA statement is this, “Open valves after connecting to a sewer source and I take no responsibility as to what comes out of which valve!” Fair enough? :D

[Sarge2]

I'd say that's the way to know for sure... If tanks are empty now, put water into sink shower and whatever else is on that gray tank and let er fly.... :)

Are labels are backwards. To tough a task for someone.

[uechikid]

Ours were backwards too.

This is NOT a post "in defense of the Keystone assembly line workers" (stastically, there's 2 valves and they get it right 50% of the time) but rather a post to explain why they are "often wrong"....

Typically, a trailer frame is pulled into the factory "upside down" and the belly is assembled. That means the tanks, wiring, insulation, axles, tires/wheels are all installed. The VALVES are installed on the tanks and the Bowden cables are routed to the top (which is on the bottom at this point). After completion, the coroplast is installed and the frame is "turned right side up" with the Bowden cables (for the tank valves) visible. Next the floor is put on the frame, screwed into place and "those two Bowden cables" are routed "together, through a little hole in the floor".... It's only after the inside walls are secured and the convenience center is installed that someone crawls into the space to put the Bowden cables in place on the convenience center wall or on the frame rail. So, what they're installing is "done in the blind" because the valves and cables are "hidden inside that little hole and not visible to the worker.

Should Keystone, in all these years, figured out a process to mark each Bowden cable ??? Heck yes, but it's "engineering, manufacturing, line chief responsibility, not "Jacob who drove his buggy to the plant at 4AM" who's responsible for making that change. Don't put all the blame on the workers, they screw up enough by themselves without being responsible for what "management hasn't resolved"... A simple piece of tape, applied to the black tank valve would assure it's always placed in the black tank hole in the convenience center, but so far, management, not the workers, have not authorized using that piece of tape.....

And folks, that’s Made In America!

We purchased a 2019 Passport 197RB last year and the labels were reversed. I removed the labels and painted the gray tank handle gray.

I've been trying to figure it out on mine, as well. Just sanitized the fresh water tank, and flushed the rest of the winterizing out of the system. When I got ready to drain, I couldn't figure which valve was which. Looked underneath and I THINK the black water tank is in the rear, which would be the rear valve as well. The surprising part was that the pipe to the valve on one tank is narrower than the other. I would have thought they'd use the wider diameter pipe for the black water, but what do I know?


I am going to try the suggestion above and see which valve drains when ONLY the grey water tank has water in it. Then, I will PAINT the flippin' handle on the BLACK valve.

[LadyFaire]

OK, using the 'only put water in ONE tank' method, I find that the rear valve (smaller diameter pipe) is indeed, the GREY water valve. So, I just need to mark the BLACK water valve to remind myself. Funny how that information is nowhere in the owner's manual....


Thank you to everyone for helping me figure this out. I have so MUCH to learn about my 'new' camper.

2020 Passport 197RB with labels installed backwards. Right now I'm just 'remembering' it. Have to address it sometime.

It’s common to use a 3” drain and pipe for the black tank, allowing the solids to flow. Gray is commonly 1 1/2” as it’s usually just liquid draining. I have seen 3” used for both but I have yet to see 1 1/2” used for the black tank drain.

[LadyFaire]

That was how I thought, too. Looking up from underneath, the fresh tank is easy to identify - the grey and black? Not so much. As it turns out, the larger pipe IS the blackwater. Glad that is all cleared up on mine.
