Second water hookup.... What is it for?
Hello everyone. I'm new to rv'ing and just bought my first 5th wheel a month ago. While hooking everything up I noticed a second water hose connection. My freshwater connection and my holding tank spout are side by side but this one is lower on the trailer, between my black and gray water tanks. Also, it has a one way valve inside of it. Is this to flush the tanks? The trailer is a 1991 holiday rambler aluma-lite.
