I'm just sitting here and wondering what the benefits of having the manifold system for the water is. I realize that if I have to repair a particular water appliance or have a leak with it, I can shut off that line.
On a Buddies Berkshire The hot water hose in the kitchen broke the first day of a one week vacation. Nether of us had a toad. Just turned off that one line and enjoyed the week. Without the manifold the whole coach would have been without water and the trip ruined.
In both my house and past RVs, one of the first things I did was to install shutoff valves at every water source. Nothing worse than having to shut off and in many cases drain a large portion of the system before starting repairs. Leaks very seldom happen at convenient times ... the Berk manifold is a beautiful thing
