I have a cousin who wants to replace the pump for his waterfall feature in his backyard. He is tired of submersible pumps that don't last so we are considering going with a centrifugal inline pump. Here's the question... If I wanted to use an inexpensive harbor freight style pump (with no prime pot), how would I keep this pump primed if it is above the "pond' level. I am thinking a swing check at the inlet pipe would keep the pump primed - what do you think? Would this work?
