2015 Cyclone 3100TH. Waste water tank pulls

[Wyndryder]

Need to know which PULL is for Black tank, Grey tank1, Grey tank 2. Dealer never showed us. Want to make sure emptying properly.

I would suggest getting 3-4 different food colors and dump about 5 gallons down each drain. Hint write down what color was dump in which drain or you could end up doing it again, I know.

Even if somebody told you which is which valve, your rig could be different.

Thank you David, great idea.
