Loosing pressure -troubleshooting please- got the answer

[Texreefer]

Dang, I would have been the winner if I didn't have to work so much. Glad it is working for you now. And in the future a kick is always good if the impeller doesn't start up right away, loosens the salt residue on it. Different symptoms than what you had. I did know the answer to this one without peaking at Kevin's answer. I feel smart, even if I didn't win.

Just for future reference if anyone sees this... I knew the pump was starting but it can also run without pumping..(cavitate= 1. The sudden formation and collapse of low-pressure bubbles in liquids by means of mechanical forces, such as those resulting from rotation of a marine propeller) sometimes giving it a bump will clear this problem and it will start up. was not the case here but a likely scenario
