Fresh Water Tank Pump Not Priming - Solution - LE I

Quick tip: if you fill your fresh tank and then can’t get the pump to pull you can break the suction lock by hooking up to the boondocking port and running water through the pump into the tank. Full details below. Thanks to the authors of several threads that I can't find for the life of me again that suggested the cup fill, city water, and the boondock method that ultimately worked for me. If I can ever find those posts again, I will properly credit them.

Full details 
Picked up Reset LE I Hull 1030 today after first year service at the mothership. Staying tonight at the campground, and since it’s predicted to be 20F overnight did not want to leave a hose out to freeze. 

So, I put a half load in the fresh tank for onboard water needs. I know the pump was working at drop off since we did a Harvest Host night on the way out and all worked fine.
After filling the fresh tank, I started the pump and it ran - but ran continuously. No water flow at the kitchen or bathroom sinks.

Based on posts in this forum I checked filter screen for plastic chips. While there were a few in there it was not enough to block flow completely. I also used the trick of filling the filter screen cup with water to try to get it to prime. No joy.

Of course, service is gone for the weekend at this point, so we are alone on the campground trying to figure out what to do. Searching the forums turns up the suggestion to fill the city water side then switch to tanks. Did that and did not get the pump to prime after switching back to the fresh tank.

Finally came across the idea for breaking a vacuum lock through the boondocking port. Hooked up the campground water to the boondock port with valves in boondock configuration. I turned on the water and ran the pump for about 5 seconds while I could hear the tank filling from the boondock port. Turned off the water to the boondock port and reconfigured the valves to normal and started the pump. Got pressure and flow immediately. Success and no frozen hoses overnight.
