Hi Everyone

Quick question ... After replacing the manifold on my filter I have a steady leak coming from the belly clamp. I want to open it up and re-seat the o-ring. Can I simply bleed our the air and open filter, re-seat o-ring and put the pump back on? Or do I need to backwash/rinse filter and then open it up? Do I need to replace all of the DE I just put in?

Any suggestions? Thanks
