Gray water valve...

I'm new to RV'ing. I have a Wildcat T26FBS and went out to drain the gray water. There is a black valve and then 2 gray valves. Are there 2 gray water valves, one for the galley and one for the bathroom? I've watched several "how to" videos showing how to drain black water and gray water but none of them showed 2 gray valves along with a black one.

Anyone out there help me?

Some campers do have 2 grey tanks and yours appears to be one of them. The procedure is is still the same. Dump and rinse your black first then dump grey 1 followed by grey 2.

Yes, two grey valves. One tank for the bathroom (sink and shower/tub) and one tank for the galley. (kitchen)

Drain as described above.

My Wildcat 327 ck 2015 has two gray tanks just like yours. We just drain the black and then the grays one at a time when they are full.
