Leak under outdoor sink.

[Beeman744]

I have found a leak under my outdoor sink. When pump is on I can hear it dripping. I can move the hot water line by reaching in the door where all my plumbing is and it gets worse. The pump is also running short intervals. There is no access to the bottom of the sink. Can the sink be lifted out of the counter top so the hose could be re-crimped? It doesn't seem to be glued down. I do not want to pry on it in fear of breaking it or damaging the counter top. Any help appreciated.

No access to bottom of sink? I would have to look for some way to access the bottom and then look or feel for fasteners all around the outside of the bottom of the sink. I would not expect to find it simply setting in place due to the bouncing an RV takes.
If that is not practical and you can get a putty knife under the rim, it might be worth doing a bit of "feel" to see if there is an adhesive knowing it down. RV are not always made to be easy to maintain but often more built for ease of building.
A call to Winnebago might also get good info if a better answer doesn't show up here?
Just my thoughts without looking at what you have.
