holding tanks.

sorry new to this and camper
2007 couger 289bhs 5thwheel

the display panel in the kitchen (isn't accurate) says

Galley
grey
black
fresh
batteries

I only see 1 grey tank handle, 1 black tank handle, and the main discharge handle at the outlet. is there a galley grey handle or do those tanks work together?

The Keystone specifications reflect your trailer was "built with" the following:

Fresh Water 45 gal
Waste Water 38 gal
Gray Water 76 gal

Typically, when the gray water capacity is "double the waste water capacity" it's contained in 3 equal size holding tanks... In your trailer, I'd suspect that either you've not yet found the third handle, the valve failed and someone opened it "permanently" and removed/lost the handle or modified the trailer (without modifying the status panel)....

I'd suspect the two handles you've found are located in the same vicinity ???

If so, EMPTY YOUR GRAY TANK and close those two valves, run water in the kitchen with the sewer cap removed and see if water flows out of the sewer connection... If it does, you've got a third handle that's open or missing. If it doesn't, then open the gray tank valve and see if water is released...

Remember that you'll almost always have a "residual trickle" so don't confuse the "cup of water" with the 10 gallons you ran down the sink..... You "should have" a nearly equal amount "down the sink" and "out the sewer"...

My guess is, you have simply overlooked the galley gray tank valve handle... It's typically "well hidden" either through the frame rail, just in front of, just behind the tires or even "between the two tires, above the equalizer that supports the axle springs.... Seldom are the two gray tank dump valves co-located in the same area.....

ok- so I think you were right on-

grey and black handles side by side before the tires, grey galley handle right in front of tire at discharge outlet.
