Hey Rory, I think in that "RDSB in a bucket" thread, they were referring to uniseals but just calling them "curved bulkheads".
I'm using 1" uniseals externally in my RDSB-in-a-bucket and in three months there hasn't been a leak. It could just be that some are better than others? But what I had to do is really reef the pipe into the uniseal to give pressure on the seal keeping it watertight. However, this may not be a fair comparison as it's a low-pressure situation. Then again though, a skimmer isn't exactly a pressurized vessel .. I don't see why it wouldn't work.
The one concern, I think, you may have still after that, is that if you bump the pipe you might dislodge it and then you might have a leak on your hands, since it's just a pressure-fit instead of a solid welded connection.
So anyhow ... What I'd do, is consider using bushings. They can be used like bulkheads but are less bulky. You'd have to seal the bushing with something like weldon-16. It won't be going anywhere after that and will be watertight. Something like a 1.25 slip to 1" threaded, then you thread your pump attachments to that piece, and you're done.
But if you want to try the uniseals, I think I have some extra 1" uniseals, since they were a pain to find I ordered more than I needed just in case someone in Calgary ever wanted any. The only drawback is that you'll need a bigger hole for the uniseals than you will for a bushing, so there's kind of no turning back. Well, that's not entirely true .. you can always patch in the hole using the plug you cut out, welding it in place with weld-on 16. I did this (I didn't like where I had cut my first hole), it works fine, it's just not very pretty.
