Loss of water pressure and water temperature inside the Motorhome?
Here is what we found out as how-to-fix, the issue. At some point, someone (ME) had turned on the outside shower hose cold and hot water. The Problem was that I had turned off the water flow on the shower head (OUTSIDE), I had turned on the Value water, both Hot & Cold. Then turned off on outside shower head. Doing this kept the water heater set to a low temp. How to FIX. Go outside to the OUTSIDE WATER HOSE and turn off using the outside
"VALUES" Hot and Cold as this will let water flow into the heater for heating. Turning water shower out off on hose caps for use only short-term.
BUT ALWAYS TURN OFF OUTSIDE SHOWER VALES and not the SHOWER HEAD.
