Sched 80 is so overkill for this, completely a waste. Get a normal "cheapo" and buy an extra frag with the money you saved!

Well, it's comforting to know that if you ever decide to do a 20' tall columnar tank to follow your staircase from the basement to the upperfloors, what size hole you'll need for the bottom bulkheads. :)

(I have seen tanks like this BTW .. I think it was a restaurant chain in the U.S. called "The Aquarium". :lol:)

I agree completely they are overkill, but for $22 versus $13, well worth the peace of mind after seeing the results of a failed bulkhead. Chances are it was from over tightening, but none the less, any bulkhead can fail.

After dealing with cracked bulkheads, both in sch40 & sch80, I will now only use Hayward Sch80s. I'd recommend the same for anyone, and I believey you can get them from Bulk Reef Supply. (they also list hole sizes for each type)

How do people crack bulkheads?? I've never personally seen one crack, either during install or afterwards. I guess to each their own, but most of my plumbing isn't even sch 40.

+1 .. how exactly do you crack a bulkhead?? Are people overtightening these things ten times over?? You realize that amount of tension is bad for the glass too right? ... Hand tighten and then maybe a 1/4 turn with a wrench after that. If it's still leaking, something is wrong. If you're really paranoid, put a little silicone down. Shouldn't have to be anything more than that.

I have a spare from my old 90 somewhere in my "extra parts bin". I remember it costing a small fortune so hopefully it is the better quality one, although I wouldn't be surprised if it was the cheapo.

if some one cracks a bulkhead that is not the fault of the bulkhead, but rather the instalation. you either tightened it way way to much , in which case your lucky the glass didn't break or you tried to force plumbing which placed a strain on the bulkhead, and again your lucky the glass didn't break.

take a look at the PSI rating for Sched 40 and let me know if you have anything on your fishtank that even comes close to 1/4 of its rating.

Sched 80 is a waist of money and is bulky , cumbersome and ugly, I used sched 80 on my old tank and never will use them again if only for the physical size of area clear they need to be able to tighten them.
