Where is the Kitchen Grey Water Tank Handle ?

[mrochin]

I have come up with an issue of my sink backing up in the kitchen. I have snaked the whole line and found no blockage, which leads me to think that there is a separate grey tank for the kitchen. We purchased the trailer in November and quickly skirted it for winter. I can not find a second grey tank lever. I don't want to unskirt the back of the trailer to find it. Can anyone help with the possible lever location for this second grey tank? 2008 Cyclone 4012 with only one bathroom

Mine has 3 drains, Black water, Gray water, and another drain for the galley. The galley drain handle is mounted right next to the hose connection

This is where my kitchen pull is.

Mine is in the same compartment at the back of the box.
