HELP Bulkhead for 55 gallon

[Fijikid]

Hello!

I know there's a ton of information on bulkheads out there but can some one tell me from experiecne what size of bulkhead fitting they recomened for a 55 gallon draining into a 29 gallon sump?

Thank you!!!!!

I had a 1" but it almost was too small. I would go at least 1 1/4" (in a 55)

A 1 inch bulkhead will handle about 800 gph I think (atleast that's what the CPR overflow rated for 800 gph uses). I've always used 1 inch drains that worked fine running about 700-800 gph of flow. If you want to be safe, I'd go probably a half size bigger and that should be sufficient for that setup. Just a thought...

im gonna do two 1-3/4" bulb heads in my 150

Use this Calc to determine size. Figure how many GPH you want and go from there.

So far it sound like one bulkhead that is 1 1/2" through the back of tank would be sufficient. What do you all think? Do you think there would be any noise issues with this size?

Thanks again!

I would do a 1 1/2" It is easy to slow it down. Increasing it is another story.
Also depend on what pump you plan to use for a return.
