I have a 2014 Thor Citation Mercedes Sprinter. It appears to have a leak in the plumbing system. When I try to load water into the tank, a large portion leaks out from underneath. When I try to use the water in the tank, the rest pours out from underneath as well. There are no leaks inside the cabin or underneath the main bed, where the pump resides.
How do I fix this leak? Any thoughts and suggestions are very, very welcome. Also if you know of a good RV Service place in Denver, CO let me know. I've had very poor experiences at Camping World in Golden, CO. You can contact me directly at email@example.com
