Not leaking too bad. The question I have for you is that it leaking at the connection right behind the main filter, on the bottom of the filtration unit. Is that the push lock female (PL-1002)? What exactly does the push lock do? Is it supposed to spin? That is where I think it is leaking. I know its a pretty bad explanation, but guys w/ a 150 gph may know what I am talking about. Anyone have problems w/ this?
