Plumbing Question (with diagram)

I've been unable to find a plumbing diagram for my coach (1997 U320) so I've attempted to make one for myself. (and anyone else who wants it). My question is...is this diagram correct? I'm not sure if I have the water heater and outdoor faucet connections correct or reversed. Either way there seems to be no way to cut off the water to the outdoor faucet when shore water is present. Is this correct?

Chaz,

On our '97 U320 the "shore water inlet" connects right at the fill valve. Basically just turn it over from it's present position & attach it to the bottom side of the fill valve. Our hot & cold from the outside faucet is connected to the bottom valves on the "Manabloc" We also have a check valve (back flow preventer) in the fitting right where you hook up your hose to.  Other than these things ours is the same.

My 98 U270 has the outdoor faucet connected to valves on the Manabloc.  Those lines run up and over the top of the waste tanks.  The shore water inlet is separate and runs underneath the waste tanks which will freeze solid if you are in subzero temperatures a lot.

Thanks for the replies. It does seem odd that my outdoor faucet runs off a pair of tees instead of out of the Manabloc since it does have an unused pair of outlets.

Ours goes thru the Manibloc valves so can be shut off from both sources (which it always is)

Our water fill valve is under the sink and is "Tee'd" off of the cold water side of the Manibloc shower valve. I am going to add a solenoid valve for the water fill and remove the Tee from the shower line. I rerouted the external faucet under the grey tank and they run alongside the city water inlet.
