Hmm his post is very low so I wouldn't expect him to own up to the issues your having with your pump. I recently bought a SWC180 on MR and I went to his place and checked it out first before purchasing it. I haven't had much issues with mine except it overflows sometimes when I add too much food. Also wet epoxy will make it overflow for a few days if not careful. I can't believe you got screwed with 3 broken bumps. I guess when it sound too good to be true... But I saw on MR that someone is trading for a sk2500 http://www.manhattanreefs.com/forum/sale-trade/118701-sicce-psk-2500-ft.html is that the same pumps your using?
