Fresh tank fill leak
Sunseeker 2860DS. Went to fill up our water tank for the first trip this season and when I started adding water, I got a big leak coming down into our wet bay where the black/gray tank valves are. Could it be a check valve problem or a leak? I looked at the water tank under the bed and didn't see a leak there so I am guessing it's before it gets to the tank. How can I access that area to see if a hose is leaking?
