My blue line pump appears to be leaking water from the case. I have it mounted vertically on the wall I nside a cabinet between my 250g and a the inline soft filter. The pressure looks good and flow is good but there is water dripping out of the case on the vent end (this is lowest point - mounted on the wall with the inlet facing up). I've checked the seal around the impeller housing. Before I take it apart (and disable the main filter on my tank) I thought I'd reach out for suggestions.
