Hi Bill - I don't know if I'm missing something here, but the bulkheads I
use are threaded all the way through - can't you use a male connection on
the "pond" side so the nut and rest of bulkhead is "outside" the pond?
Just a thought - Gale :~)
I ran into a snag plumbing the skimmer, I didn't have the piece to join
the bulkead to the elbow. I'm not really crazy about having the bulhead
protruding into the pond (nut in pond), but I don't see much choice based
on the fittings available. I want to be able to unscrew the skimmer in
winter, so I don't want to go the pipe boot route.

Plan A was to put the nut outside the pond and the flange inside the pond,
so that bulkhead was almost flush with the pond. I bought some cheapie
bulkheads for this that are slip/thread and a wee slip after that. But I
didn't plan on the Skimmer outlet being so far down the liner (damn that
JJ); it's something like 2' below the pond's surface. Plus the bulkhead
would be sticking out a long way from the elbow, which will present slumping
issues with this much backfill and my steep sides. So Plan B was to go with
a thread/thread bulkhead facing the other way and a spigot to MPT adapter.
Hence the missing part, I don't have the adapter.

Ideally, they'd make a threaded bushing that I could screw the bulkhead
into, but I've never seen such an animal.
