YHSublime February 22, 2014 Share February 22, 2014 So I borrowed a 1 3/4 drillbit for my 1" bulkheads in the 20 gallon. My issue is, and I don't remember it being like this the only other time I've worked with bulkheads, is that the retaining nut slides right into the hole... perfectly. The rubber gasket is only slightly bigger than the hole I drilled, so it obviously makes a seal, just seams like either I have the wrong size bulkheads, or I'm being over cautious. Thoughts, before I start attempting to plumb this bad boy? Link to comment Share on other sites More sharing options...

Der ABT February 22, 2014 Share February 22, 2014 If the outlet ring doesn't sit outside the exterior glass than either its the wrong bulk head nut or hole size Link to comment Share on other sites More sharing options...
YHSublime February 22, 2014 Author Share February 22, 2014 If the outlet ring doesn't sit outside the exterior glass than either its the wrong bulk head nut or hole size That's what I figured. The exterior ring slides perfectly into the drilled hole. I know the bulkheads are 1", I wonder if it's just the wrong size nut, came from QR when I was setting up the 150, bought extras just in case.

YHSublime February 22, 2014 Author Share February 22, 2014 I don't know when I'm going to learn my lesson about measuring first. I just measured the drillbit I had borrowed, and I've drilled 2 perfect 60mm holes, not 45mm like I thought. Looks like I'm looking for 1.5" bulkheads, there's the problem. Didn't I see Home Depot graced us with bulkheads recently? Link to comment Share on other sites More sharing options...
zygote2k February 22, 2014 Share February 22, 2014 best way to ensure you're drilling the right hole is to have the drill bit and the bulkhead on hand at same time and see if the bulkhead gets stuck in the end of the drill bit if you try to push it in.

Origami February 23, 2014 Share February 23, 2014 Two 1.5" on a 20. Awesome! Seriously, though. Watch how much load the plumbing is putting on the glass. The plumbing for 1.5" schedule 40 is a lot heavier. Sent from my LG G-Pad 8.3 Google Play Edition Link to comment Share on other sites More sharing options...
