Wow. those Abyzz pumps are crazy expensive! I will have to weigh the cost of one, versus drilling a hole into my glass sump, which I am not keen on doing. Obviously drilling is a much cheaper option, unless I crack the bloody thing. I do have a 3/4" diamond glass cutting bit I could use, along with some bulk head fittings. Would 3/4 be too small for a PanWorld?
