I have a March pump which I purchased from Midwest Supplies. It works great once it gets primed. I use it to pump hot wort through a counter flow cooler and into a corboy. The problem I have I can't prime the pump whin it is hooked up to the CFC. I have to disconnect the the hose from the CFC then get it started by pumping a small amount intp a pitcher then hooking it back up to the CFC after that it pumps great. I'm afraid I'll get burned from hot wort one of these days. The pump is several feet below the boiler outlet. Any suggestions?
