Grey Tank 2 Question

All-

I have a 13 Infinity 3470RE. My question is when we have gotten to use our trailer (twice in 12 months... It has spent over 5 month in the shop over the last 12) grey water tank 2 never takes on waste water. So, my black is filling normally and grey 1 fills quickly but grey 2 does nothing. I was told by CW that grey 2 is only for a washer dryer? This is very different from my previous experience. Is anyone else's Infinity trailer plumbed this way?
