New Sierra 5th wheel question

[dlarimer]

Just bought a Sierra 372LOK. When I dump the tanks nothing comes out when I pull the handle labeled grey two. The dealer said this tank collects the kitchen sink water and outside kitchen sink water. The level indicator for grey two indicates empty. There is also a galley tank indicator that indicates full. If the grey two tank is in fact empty where does the kitchen sink water going. I turn on the kitchen sink faucet and no water comes out of either valves.

my 381RBOK Sierra has another set of t handles for the galley and rear bathroom grey water. they are located along the frame behind the wheels.

It could be that your tank handles are mislabeled. It wouldn't be the first time that has happened. You may need to experiment a little to determine specifically which handle goes to which tank.

On our 2015 Sierra 360PDEK the outside kitchen and inside kitchen sinks drain into the galley tank. Washing machine, shower and bath sink to gray tank. My handles are also labeled as such. My command center quit working over the spring so I can't tell tank level anymore.

It may be going into your black tank.
