Hey Brett, this is what I did with my skimmer:
It's a beckett, so high flow. Did the trick for me. I had it with just a 90 before but it was noisy and the skimmer instructions said not to submerse the drain, but I don't like salt creep so this is what I did. The valve just allows you to make it quiet. I cut and added a T. You should have room to do that. Just have to guy fine a sched 80 "T" and a grey John Guest fitting, or a red one so that everything matches.
Since it's in the sump, I didn't even glue anything.
Hope this helps.
