Hi! The outlet pipe coming out of my DE filter (FNS Plus 60 sq. ft) has a slow leak where indicated in the photos. From the parts diagram it looks like the leak is coming from part numbers 28 or 29 where the pipe meets the filter. I'd like to detach the outlet pipe from the filter housing but I don't have a wrench big enough (the diameter is large) and it's too tight to loosen by hand. How would you go about removing the outlet pipe from the filter? Do I need a special wrench? Also, does anyone know if there other ways I can try and diagnose/fix this leak? Thank you!!!

Strap wrench worked to loosen the outlet coupling. Unfortunately I wasn't able to fix the leak with re-tightening it with lube on the threads. Now I can't get it to loosen again. I'll try again after I drain the filter to clean the grids.

You should not have to lube the threads on unions, you can/should lube the o-ring/gasket.
Gasket my be bad, pinched, ect. It looks like an o-ring, so you might be able to get one at the hardware store or big box store its its bad.
When tightening, you should do it by hand, hand tight, then another 1/4, half turn with the wrench
