Help with Filling Water Tank

We are getting ready to take our '73 O'Lander out for the first time since we purchased it last year. I checked everything out when we brought it home and everything checked out fine. I winterized it and now seem to have issues with filling the water tank with the city water connection. All 5 drain valves are closed (the 2 in the back roadside compartment and the 3 under the sink). When I turn the city water on to fill and pressurize, the water just runs out of the back drain tube. What gives? Any help would be appreciated. Those valves are so confusing.

well...first of all, with the "stock" configuration, you can't fill the water tank with the city water connection. You fill it through the water filler spout.

with the city water connected and all the valves closed, the city water pressure will simply pressurize the pipes. (there's a check-valve that prevents water from getting into the tank; the pump can pressurize the lines from the other end, but water can't flow back toward the tank. there's a check-valve on the other end of the system, as well, just before the city water inlet, that keeps pumped water from going out there). If water is coming out the back drain, either the valve is actually open, or the pressure relief valve is stuck open...or not "stuck" and doing its job of relieving excessive line pressure...which would mean that your on-board regulator isn't doing its job.

you'll have to figure out which drain tube its coming out of; look under the back, and you should see 2. Then go look under the bathroom sink and see if you can deterimine if its the drain valve, or relief.
