CY4000 black and #1 grey tank levers...which is which?

[remoandiris]

My newly received 2014 4000 has one grey tank lever and the black tank lever in the same opening. Neither is labeled. Any idea which is which? The owners manual (yes, read it cover to cover) doesn't say. I expected them to be labeled, just like on my old Jayco, so I failed to closely follow that step during the walk thru.

If all else fails, I'll attach one of those clear tubes to the outlet and pull the lever, then mark as appropriate.

Had the same issue with my 4100, have 3 levers in front, my middle lever turned out to be the black, other 2 are grey...

Left one should be black and the right one gray

If all tanks are empty, you can open all valves and start a faucet in the kitchen to see which valve stops the water flow. Then open a faucet in the bathroom and see which valve stops the water flow. The remaining valve is the black tank and you can test it with the black tank flush.

Turned out the left is grey and the right is black. Black tank handle is on a swivel of some sort.
