bulkheads and diameters and stuffs

[christyf5]

Hey guys, hopefully someone knows what I'm talking about here and can help.

If you have a hole drilled in a tank for the overflow and its 3 inches in diameter, is there any way to tell:

1. how big of a bulkhead you need (ie. is it just a 3 inch bulkhead?)
2. what diameter your overflow piping will be? (are you stuck with
whatever a 3 inch bulkhead offers?

Christy get ahold of Mr Alberta AKA Harvey he knows the sizes for you, i ,but im a little unsure of the bulkhead sizes. so i wont add anything..

Christy a 3" hole is for a 2" bulkhead.

A 2" bulkhead will give you a 2" drain pipe. If that's too big you can always add a reducer to it.

Thanks guys!

I figured as much. The bulkhead I have now seemed rather large for a 1-1/4" pipe, I can see theres a reducer on it but its all been glued together so I can't get it apart to see whats going on.

With the sch80 bulkheads I always use both 1.5" and 2" bulkheads require 3" holes.

Also Christy, if you look at the bulkheads on J&L's they tell you what size hole you need for theres, so you can always use that as a referance.

They don't sell the *really* good ones. As spshelps mentioned, Schedule 80 !! Sure the cheapo black ones get the job done, but hand-in-hand compared to a schedule 80 you know you will have peace of mind with sch80 bulkheads

Glass-holes.com are also really good for info and they have decent prices too. I've ordered hole saws and bulkheads from them in the past.
