So I just swapped into a new CCP520 filter shell, but when I re-attached my existing plumbing to the inlet, I have a slow leak no matter how tight I set the attach fitting (outlet connection is just fine, BTW). Should I lube the o-ring? If replacing the o-ring is the better answer, would anyone have a part number for it? Thanks!

If you reused the old o-ring, replace it. Lube it with a non ptfe lubricant like Magic Lube 2. Bulkhead o-ring is Pentair #86006900.

The part number I gave you was #22….where the bulkhead inserts into the filter housing. Is this indeed where you are leaking or are you leaking at the union itself? #16/17?
