Need help picking a bulkhead!

[Sythero]

Hey all,

I will be using this hole (1-3/4in) as a drain to my sump. On the top of the bulkhead will be a Durso, and on the bottom will be PVC pipes to the sump.

Which bulkhead is for me? I don't want my new tank to leak.

Thanks.

You'd want a bulk head that is 43-44mm in diameter and if it's made out of ABS you'll have to use transition glue to go to PVC or buy a threaded one and use Teflon tape so you would probably go with the 1 inch abs from BRS they are sch40 or melvsreef sells sch40 PVC bulkheads there a little more money but you won't have to buy the transition cement

What style would it be? threaded/threaded?

That's up to you if you would rather use a fitting that screws in or if you'd want to glue your PVC directly into the bulkhead, but you'll want to get a 1 inch sch40 bulkhead either way

I'd counsel against glues. I've had to replace a bulkhead connector, 2 of them, just from age, and I was so glad nothing was glued: it all unscrewed. My recommendation is threaded, and with a threaded interior projection that can take a 'cap' screwed on if you have to work on the sump or pump. Capping the interior end means you don't have to drain the sump.
I put the gasket on the inside of the sump, and hand-screw it to moderate tightness: too much can crack the sump wall. A 5' 6" woman can do it without tools, if that's a clue. You may get a tiny seepage from a new connection, but wrapping it in paper towel often suffices: calcium carbonate accretion soon stops the leak.

If you go to Coralvue's website, you can purchase reef octopus schedule 80 bulkheads (1 inch) that fit in the regular 1-3/4 inch hole like the regular black pvc/abs ones. These are way better than the black ones that people tend to have issues with over time. They also use seated o-rings instead if a flimsy rubber washer and they provide an excellent seal. I've used them on 2 tanks now and they are awesome.

Is slip or threaded easier?

So which one do you think would be best?

The reef octopus ones I referred to are slip on both sides. You just pvc glue the dry side, wet side doesn't need glue. Imo, slip is easier and less likely to give you any leak issues like threaded joints can if not done properly. You can add slip unions into the plumbing so you can disconnect some of the piping for maintenance if needed.
