While camping this past weekend I noticed water dripping from the fresh water tank. Upon inspection it looks like there is a crack around the drain plug where it meets the bottom of the tank (see pic). From the pic it also looks like there is a failure in the silicon (or other caulking material) that binds the flange of the plug to the tank. But I’m not sure about this, maybe the crack is a brittle failure of the tank plastic.
Anyone knows what’s going on here? I’m contemplating slapping some silicon caulk on there to see if it holds.
Also, I was hooked up to city water at the time and the tank was empty prior. I thought city water supply bypassed the holding tank? Am I misunderstanding something here?
Thanks
