Pete,
Thank you! I figured it out I think. My leak was where the cold water entered the heater. I shut OFF the water to the heater as you said, the leak stopped and I was able to check for other leaks, none found, water pump did not cycle after 2 hours so, maybe a good sign.
Connie questioned my having a "pro" fix the tiny leak. It really is right in front of my nose!
But, my luck is like this:
Shut off the supply to the heater. Cool! Turned on water pump, water everywhere! I did not put the water filter back on. Realized that. Shut it off and jumped inside the storage bay with towels! Hit my head and ear on the over hang. I have a blood blister on my right ear and a headache now.
I did survive checking the battery fluid levels. Found both positive wing nuts loose and black plastic grounds all over the batteries where the factory drilled holes in the covers for the wires and vent hoses to come out. The levels were right where they should be and my experience with water says leave it alone.
Just another RV prep day. I am learning slowly.
Almost one year now as member and we thank all of you for your help, and fellowship at the one tiny rally we attended.
Just want to hook up and go!
Walt
