Bulkhead advice...

BBoley24 · Oct 17, 2012

Ill be moving to a new apartment soon so I will have an opportunity to change out the bulkheads.  Unfortunately Deep Blue Professional does not have a phone number and won't respond to my emails so I am stuck trying to find out the exact diameter of the standard holes that they drilled.  All I know is that one is 1" and another is 3/4".  I want to go sch80 as i am tired of the stupid thing slipping and the rings popping off of the stock bulkheads.   Does anyone know of the official diameter cut from a deep blue 75g rimless edge tank? I ordered both hayward sch80 at 1 7/8" for a 1 inch bulkhead and a corresponding 3/4" and I ordered on the safe side the standard LifeGuard 1 and 3/4" bulkheads just in case those don't fit. Input?

Schedule 80 bulkheads have a much larger outside diameter so they will not even come close to fitting in standard size sch 40 bulkhead drilled hole sizes. You should be able to find the standard and sch 80 hole sizes at glass holes . com

Yeah, I got an email today from DBA. They claim their hole sizes are 1 1/2 and 1 3/4. The sch80 is 1 7/8. What a bummer. Hopefully the lifeguard standards will meet my standards!

You can always redrill them, I bought my drill bits at BRS. Just drill a piece of plywood slightly bigger than the new drill bit and use that as a guide to get you started. Or do what I did . I went from a 75mm to 85mm hole which is only about 3/8 bigger. Tip the edge of bit where you want it to get it started then slowly level it off to go straight thru the glass. GL
