My name is Rich, I live in Colorado, I’m recently retired a bought my first RV. It’s a 2000 Jayco Eagle 26P Class C with a Slide out. I’m trying to learn how everything works. The RV came with no manuals but I’ve managed to find almost everything online. The one manual I lack is the water system. This RV has one water hookup that takes care of the tank and city water. There are 2 valves with blue handles but I do not know what position they need to be in for different situations like Travel, campsite, winterizing and anything else. The RV does not have a water port to just stick a hose in to fill the tank. I’ve tried contacting the Jayco people but they won’t respond. Hoping someone on this site can help.
