Thanks to everyone for their suggestions. I tried all of them except the plunger, which I also thought was a good idea but did not make it to the hardware store. Nothing worked, I could not get the pump to prime up again. My pump is labeled as a Dometic model 336185 which turns out to be manufactured by March Pumps and the March model number is LC-3CP-MD-115. I downloaded the March owners manual and installation manual and that is when I discovered the problem. My pump is mounted 12 inches above the raw water strainer. The installation manual is clear that this pump cannot self prime and the suction inlet must be flooded. How can Four Winns not know that? Please do me a favor and let me know if your pump is installed with a flooded inlet, or even better post a photo of your pump installation relative to the raw water strainer. Thanks, RD
Not sure if this is still an issue for you but I bought a mini plunger from amazon and it worked great. 3 pumps on the AC water out thru hull and the AC system fired right up spitting water. Got to love a $10 solution and minimal effort to solve a problem !!
