Outdoor Kitchen Sink won't drain

We have a 2015 Vibe 268RKS. The inside kitchen sink drains fine. The valve under the slide is open. However the outdoor sink isn't draining. Any thoughts? Much appreciated!

Look for another valve to open. Some have been under the camper with no handle and a couple of reports of them in side of the underbelly.

If no luck I would contact dealer or FR for further information.

Try opposite side from ok sink on frame. T handle kinda hard to find. May have to lay down to see if can't locate by feeling around.

Is your outdoor kitchen sink draining to your black or grey water tank? On our 8312SS, the outdoor sink is plumbed to the black tank. After the black tank fills to just over 2/3, the outdoor sink will stop draining freely.

He may have one of the weird ones that have no tank and drain to a gate valve. Valve has to be open to drain sink. I guess either full hookups or a sewer tote is required for that type.

I have the same trailer - 68 RKS have had the exact same issue. Look underneath the sink on the pull out unit and there is a black pipe with AP trap in it. After the P trap it goes into a black horizontal PVC pipe. Where the P trap enters the pipe there is actually a one-way rubber valve, almost like a condom boot. Unscrew the P trap and get to the straight section of pipe and push the rubber boot back in so that it's in line with the black pipe. The reason this valve switched on you is the grey water tank filled up by your kitchen sink, which is lower than you're outside sink. It stops it from backing up the sink and running outside.
