This novice would greatly appreciate any help from the educated posters in this forum. I have a 1/2 HP Flotec shallow well pump that I use for a small cabin. The pump is only 5 months old, and has worked well all summer. This weekend, for some insane reason my dad took out the priming plug to prime the pump even though it was running fine. The pump is now not drawing water from the well. And numerous attempts to prime the pump as I have always done in the past were unsucessful because the pump will not take anymore water. When priming, the water does not draw down, but I don't get a prime either. And after doing this for about 20-30 mins the pump will start to get very hot. Any idea why I can't get the pump to take in anymore water to prime it? Or am I missing an obvious reason? Very grateful for any advice.
