Welcome to the world of Vintage Overlander ownership!

The unit was sitting for at least a couple of years so could a valve have ceased??? Previous owner was no help.
Appreciate all help.
I agree with John that you likely have one or more open low point drains in your coach. Even with the city water, at least on the Vintage coaches, all of the low point drains must be closed before the water system functions properly either on the demand side or city supply side. The valves that I most frequently forget about on my Overlander are those under the beds mid-coach - - one for the fresh water tank and the other for the water heater.
A second problem that might impact your city water service is a valve that may not have been used by the time your coach was produced. I am not sure when the "City/Demand" water valve disappeared, but if your coach has one, it is typically between the city water supply and the pressure regulator that John mentioned in his post - - adjusting the direction that the handle points on this valve determines whether the coach functions on the city water supply or the on-board demand system. I believe this valve disappeared when check-valves were added to the water pumps.
Good luck with your search for the water system gremlin!
