I've had my coach now for a few years and noticed that the expansion tank level is always between cold and hot markings, never changes. This week, I replaced the expansion tank return hose which had been separated from the filler neck and replaced the 13# pressure cap then filled the expansion tank to the full mark. After a couple hours running and a cool down period there was no change is the expansion tank level. So now what?

As far as hot showers and other running water goes, my vintage Aqua Hot AHE-100 series works great although I can't say much about the floor vents. The rear seem weak, the mid-ship works great and the front are hardly noticeable. Thanks, Jim E.

 

The AV Expert of youtube fame is shown tapping on cold check valves to unstick them. I believe he states it is a common problem on seldom used coaches.
