You guys have me totally bummed! I had hoped that my PS4 just needed to break in...then thought I would empty the sump, clean the pump, put in some 45's to replace the 90 and hope that would fix it! But according to you...it's a whole lot of work for nothing!....
Perhaps I should just look for a new return pump???????????
