Drilling 180

[jherrin215]

I am getting my 180 drilled soon as I have decided to go with it instead of my drilled 125. I need to know how big and what spacing I need to get it drilled. I am going to be using a 1 inch sea swirl for the return, and the holes will just be for the overflow. The holes are going to be on the back towards the top. Can someone give me some advice on where to put them and how to plumb them?? I like the way TSwifty has his done but don't really understand the whole setup. I'm new at this so I will take any advice and give it a good once over!! Thanks in Advance!!

You might want to ask this question over in our DIY forum. I'm really not sure how big the holes need to be, but I'm assuming that they need to be at least 1", as that's the inside diameter of the swirl's plumbing. you'll get much better information over there.

A 1" return requires a 1 1/4" O.D. bulkhead, and larger if going with a schedule 80.
I'd be holding my bulkhead in my hand to measure before I selected my drill hole diameter.
A 1" pressure feed line (maxed out) will require a 1 1/2" gravity drain line for out flow.
I hear Tswifty's design is dead silent, which is important to most experienced reefer's.
