Hi again. Going on 4 weeks now without a pump. Been doing lots of internet research to find what I think will suit my needs but I have hit a snag. The pump I want does not come with a power cord. I have seen other pumps offered with 3', 6', or 25' power cords. My old pump cord has the standard 3 prong plug, but the grounding prong broke off a couple of months back, so I can't re-use it. Currently I do not have the set up or funds to hard wire a pump so I need a cord. How do I make sure I am getting the right cord for my pump? How do the cords typically connect?
