The pump came, and does not connect. According to the diagram online, the attachment kit ( female 1") should just slip on to the input point on this pump ( it is 1/2" female), with only needing a black ring to secure. It does not fot it, is too big. I tried to get an adapeter, and I broke the ceramic post during the process. I am very frustrated. I've gone a week with out a skimmer. I just spent over $100 to get a replacement that did not work. I will take a picture and sent it via email. Please advise...
