Bulkhead/Drilling tank

Hey all, im in the process now of planning a new build. it will be a 29 gallon (downgrade from my 55). I would prefer to have it drilled because i would like to have a close loop on this tank. What i would like to do is have a 3/4" drain in the middle of the back wall and id like to have two 1/2" returns drilled in the left and right corners. Ive been calling around to have it professionally drilled but im unsure of the hole sizes i should have drilled. So my question is what size hole would i need for a 3/4" and 1/2" bulkheads? Thanks in advance!

 

You will need to find diameter of bulkhead you are buying to size hole correctly.

 

Your standard schedule 40 1/2" bulkheads need a 1 1/4" hole, 3/4" requires a 1 1/2".

Hope that helps

 

Ha! good call. didnt even think about that =0)

So yeah, 1 1/4" and 1 1/2" will work?
