I just purchased a 2018 Winnebago Era 70X. I've been learning its ins and outs over the last couple of weeks and have only been stymied by getting hot water to flow in the sink and shower. It has a Trumbi water heater, which definitely fills with and heats water (I can monitor this clearly). That said, I get nothing but cold water from the outlets. So, I'm in search of the water heater bypass valve, which I assume is still on since the rig was still winterized at purchase. For the life of me, I cannot find this valve and I have diligently used the manuals, which indicate the bypass valve I'm looking for is under the couch (passenger side). In this location there are hot and cold water drain valves, but no bypass valve. Does anyone happen to know the location of this mysterious destination (or, if I'm just overlooking the obvious, can someone tell me what I'm missing?)?. Thanks much.
