Just bought a 2008 Fleetwood terry 295tsrl a week ago and been living in it. This morning my wife started doing dishes and went to drain and it went down about 3" and stopped. Don't wanna unscew the vacuum breaker for fear of it filling my cabinet with water. Went ahead and drained the black and grey tanks and the sink is still full. From reading online it says this thing has 2 grey tanks. But the underside is covered with just the 1 grey and 1 black line coming out and connecting. Then at the back there is a small 1" or so drain I'm assuming is for fresh water as it is directly below the fresh water tank. Went ahead and drained it as well still nothing. Other than that there are 2 small drains with screw on caps and that's all that's below the cover. Is any body familiar with these or where a second drain valve is located? Any help is appreciated. ThanksAlso it is a 5th wheel if that makes a difference. The level indicator says empty on grey and black and full on battery and galley

Disconnect the trap (U shaped PVC) under the sink and empty it. Could be the issue.

I have a rear kitchen model 5th wheel. There is a 2nd grey water drain/tank located at the back of the trailer. In my case, the handle is right behind the slide out. It seems apparent that either you have a 2nd tank, or you have a plugged drain or pipe somewhere.I've located the manual for my Mountaineer on the internet; maybe you can too, if you didn't get one. The model on Keystones is right by the door: mine is a 29RK.Added: the handle fell off my drain once, leaving only a small threaded rod. Maybe the drain handle/rod is more subtle than what you are looking for.

I have a manual that came with it. Very vague to any of the systems in this trailer. Nothing about how to drain any of the tanks, or even that it has 2. Just says to drain the holding tanks periodically

I used to have a Keystone Outback with two grey tanks and the second handle was under the slide (driver's side) between the wheels. PITA to get to when set up in a campground. Your monitor saying that Galley is full would definitely indicate that you have another tank to find and drain.The two small drains with screw on caps are the "low point" drains for hot and cold systems. Used when winterizing the trailer.

If the tank indicator says the "galley" is full then you likely have two grey water tanks. One for the galley "kitchen" and one for the bathroom. You just need to find and open the galley "kitchen" gray water dump valve.

new to campers. kitchen sink wont drain, grey tank is empty

Galley is full. You need to find that valve to pull and empty it. It is likely in another location than your other gray tank valve. On our prior TT it was up under the trailer a little in a very weird location away from black and other gray tank valves.

Ok thanks for all the help. The rod on the valve was actually broken flush with the frame but it is right in front of the driver side wheels under the slide out on this particular model. Hopefully someone else will search for this and find it helpful so they won't have to pull half the cover off the bottom side to find it

If your galley indication is saying full then it is likely your kitchen 2nd gray tank is full. Your drain valve is likely on more rear portion of FW oppisite side of entry. Probably a pull cable. You should see a section drain connection with same type connector you attach your sewer drain hose too.

Thanks for all the replys. It just makes it such a pita to look at anything up under this thing because it's covered. I'll start pulling pieces down and see what I can find and let y'all know how it goes

I don't think I would do that unless I had a container large enough to hold all the water in the sink. My Prowler has the second gray

tank at the rear and from what you stated yours probably does also.
