Water leak?
Hi guys, took out the 2018 for it's 1st shakedown trip last week and when I got home and dumped the grey water tank noticed a slight drip coming from underneath the belly pan by the valve. Is this considered "normal"? I have an appt with Airstream next week to drop it off and have them do a slight floor repair that was mentioned at PDI. Any input would be appreciated.

Hard to tell from the picture. Could it be condensation from something? Have you crawled underneath to see what's above it? Is it just coming from the belly pan?

It's coming from the corner of the pan after I flushed the grey tank. Not condensation. The larger wet spot to the left is nothing. I had rinsed off the trailer of some dirt and was from that.

The tank enclosure should not have a drip, unless you towed through rain. Both the gray and black tank are inside that metal enclosure (that enclosure is not the belly pan)
If you took warm showers during cold weather that could create condensation inside the enclosure, then it is possible for it to accumulate inside the tank enclosure which could drip.
If there has been no rain or conditions creating condensation, then something inside the tank enclosure is leaking.
To test, fill both tanks with water. If there is no recurrence of the drip, then there is no problem

Flushed gray tank? If you ment flush black tank with the tank flush system you could have a leak in the flush system. Not uncommon. There is a screw on connection inside the trailer that can loosen. Hand tighten it if loose and you are good to go.

Do you happen to know where this screw on connection is located? We have a 26 RBQ flying cloud.

It will be inside the trailer just behind where the flush is on the outside. Looks like on your 26FC it would be Streetside closet area.

Put different colored food coloring colored water in the black and gray tanks and see if the water dripping matches.

The black flush system has a vacuum breaker just inside the trailer from the exterior hose connection, these are notorious leakers and the one in our 2011 Bambi was no exception.
it spewed water in the cavity behind the lav sink where its located and would eventualy run down under the trailer.

That is how I determined both of my holding tanks were leaking at the valve to tank adapters.
