[Land Yacht]

We picked up our coach 3 days ago, Thursday 10-12-2016, as being new to us! :-) We are in Grove, OK only 30 minutes south of Newell. Our first problem seems to be limited hot water. The aquahot is showing around 200 degrees, and I feel plenty of heat coming out of the aquahot and some pipes are warm, so I think it is working OK. I tested the galley sink turning off the cold valve, then hot water valve. They seem to be functioning properly with similar water flows on both hot and cold, but hot side only gets luke warm at best. I called the Newell hotline on Friday and did some troubleshooting with Dwight, and he seems to think the valve under the Webasko black box on the side of the aquahot is calcium-ed up, as I can't rotate the black knob and the aquahot side is warm whereas, the other is only luke warm. My understanding was this was a hot-cold mixing valve which maybe letting in too much cold water and not enough hot water. Dwight said the whole Webasko unit must be removed to get to the valve. Thus, I am heading to Newell tomorrow to see if they can work me in this week. Does this sound right? Any ideas on this issue?

The second issue is poor water pressure especially in the shower. The previous owner said it was never good, and I would like to increase it significantly. Do I need a larger pump or is there an adjustment?

Finally, I had the bright idea of connecting to city water which might get me higher water pressure and maybe could clear some calcium deposits if indeed that is the luke warm water issue. I developed a leak which showed itself at the base of the step up into the rear bath with wet carpeting. I could see water dripping when I looked between the rear 2 wheels. My guess was it is either the washing machine or rear shower, so I closed the valves on both and the leak stopped and I dried out the carpet. Any ideas on this one?

As a newbie your help is greatly appreciated  :-)

Thanks
