1) Turn off water, depressurize. Done.
2) Put one wrench on the large nut.
3) Put the other wrench on the collar to the right side of the nut (closer to the filter)
4) Turn the large nut "up" (meaning clockwise from the perspective of the filter).
5) Eventually, the nut will come off the nipple for inlet side of the filter head.
6) Repeat (in mirror image form) on the outlet side.
7) Unscrew the nipples. Clean the nipples. Reapply tape to nipples.
8) Rescrew nipples (not so tight, this time).
9) Replace filter unit.
10) Align the threads on the unions and tighten nuts.
11) Turn on water at shut off--very slowly--and hope for the best.
