Dazed and Confused!

Help! We're new at this. We are trying to get the hot water to work on our 34' 93 Excella Classic and we thought it was working then it wasn't. The more we tried to figure it out the worse things got. First we hooked up the city water, turned the switch on and the Atwood propane only hot water heater fired up, but alas no hot water... Then it shut itself off. Then we thought maybe it was the bypass valve under the right twin bed. We opened that and water started running out from underneath the trailer white hose at back. So we shut that and decided to open the valves under the Bathroom sink. There are four and as soon as we did that, all hell broke loose under the trailer were the grey and black water flush is. So we turned all those off. We are not using the toilet and and had everything bypassed for winterizing last November. Not sure which valves should be open and which should be closed. The manual is not helpful. We need one of you experienced 93 excella owners to talk us through the de-winterizing and hot water heater set up. Do we even need to mess with any of the valves under the bathroom sink?

It sounds like the low point drains under the trailer may be open. My '89 Excella had 3. Two were under the kitchen area and another was below the city water connection at the rear corner of the street side. Find them and close them. The newer trailers seem to have petcocks on the belly pan. Mine had valves accessible from inside the trailer. You may not have had water in the heater due to bypassing for winterization. My Excella had a box on the water heater with a lever that would only go in 2 positions - bypass or normal use. The newer trailers have a 3-valve set up for bypass or normal use. Figure out the bypass and then turn the water on again. Oh, yes, make sure the water heater exterior drain is closed or plugged.

Cross-over valve closed, supply lines open. Valves are probably under the bed (Water will be filling the hot water heater)
Low point drain valves closed (I'm not sure where those valves are in your AS but it sounds like the low point valves are still open.)

I don't know about the valves under the sink. If there's 4 they probably do more than feed that sink. Can you upload a picture?
