Tiffin water drain lines question
I've been away from IRV2 for awhile. I have a question about water drain lines. In the photo (hopefully attached), there are three drain lines. I think the one on the right is the fresh water tank drain. It takes quite a while to drain. What are the other two for? Is one connected to the hot water heater? Thanks for any help!
