Question Water System Woes

Have been working to fix up our 1991 25' Excella and have run into a perplexing problem that I think is valve related. I'm hoping that some of you AS experts can help this new AS owner out!

When hooked up to city water my system works perfect, we have hot and cold water on demand. Now the problem -When using the water pump, the water doesn"t flow out of the cold water side but flows out the hot water side, and the water is cold. If I turn the bypass valve at the water heater to the bypass position, the water flows from both the cold side and the hot side and water stays cold. What am I missing here? Could there be a check valve or a bypass valve that I don't know about? Or is this a malfunction of some kind?

Any input would be appreciated,

It sounds like your water heater has a bypass system for winterizing. There are posts in the Winterizing and Storage section on this forum. The first post is a sticky and shows the three valves for a bypass system and what position they need to be in. Hope this helps..."Mac"

Unhappy Water system woes

Thanks Mac- but I've checked all the bypass valves and that doesn't seem to be it. With the bypass valve in the "normal" position water does not flow out of the cold water side. With the valve in the "bypass" position it flows out of cold and hot side but doesn't go through the hot water tank, i.e. there's no hot water! Again, this is just running off the water pump, everything works fine if we are hooked up with a hose.
