Fresh water tank being filled by shore water connection.
To elaborate more, I came home to my 2004 Airstream classic 30 and noticed a puddle of water on the ground just below the fresh water intake area. At this point I unlocked the cover panel and noticed a slight drip out of the over flow “outlet”. Need some assistance in identifying the issue, as of now, I have the shore water off because I figured that is somehow filling my fresh water tank up, previously the fresh water tank was about half full. Now, fresh water tank is completely full and leaking. If you can point me in the right direction, I’d appreciate it! Links to videos or post would be great. I did some research and saw other RV’s with similar issues stemming from a check valve leak??? Steps we took to try and resolve this issue, 1. turned off shore water, 2. turned on water pump for 15 mins or so, 3. open hot water in bathroom sink hoping for air to be dispersed. But nothing happened, but only tried it for a few seconds.
Appreciate any help!
