Tank Overflow Pipe Sizing Question 1

[PurewaterGuy]

I have just installed a Water Storage Tank. The dimensions are 140 Gallon Vertical - 70.25" H x 24" W

I have a Reverse Osmosis Unit filling the tank at 2.5 GPM

I am going to Plumb a overflow package to drain.

I'm thinking 1" Bulkhead fitting with 1" schedule 80 pipe

Will this be enough to handle the flow?

The 1" overflow should easily pass the influent feed of 2.5 GPM.

Worked out well. Finished the job today. Thanks for answering.
