I have a 1993 33'breakaway and am trying to find a switch valve etc that would allow me to either fill the tank with water or use land source water. I know this is a simple question but we are new to the MH and this would help. I'd love to find an owners manual for my specific unit to refer to in these kinds of situations.
Thanks

Look at your control panel. Does it have a switch that says "Auto Fill"? Our previously owned '93 did. To fill the onboard tank, we turned one valve under the sink where most of the plumbing lines are and where the on board pump is, and then pressed the "Auto Fill" switch (rocker). To use shore water, you just turn the "Auto Fill" off, turn the valve off, and you're on shore water.
