Well, to be fair, the pump kit doesn't include all the o-rings
(e.g., the GO-KIT38 doesn't have the two drain plug o-rings).


Jump off the porch and try something for the drain plug O-rings.

Replace the old O-ring with faucet stem packing. Couple or less
wraps around the thumb screw, then tighten snug.

My solar panels inline pump pipe T-stat had and O-ring go bad and
leak. I used the stem packing to replace the O-ring. The pool guy
was impressed.. never a leak.
