Bulk head flow rating??

[reefchaos]

Does anyone know the flow rating through a 1", 1.25", 1.5" and 2" bulkhead. I am trying to plan for the flow through my overflows, and was curious if anyone knew this information or had a link to it?

Thanks
Erik

1.00"=~600GPH
1.25"=~910GPH
1.50"=~1325GPH
2.00"=~2350GPH

It's safe to say these numbers are under perfect conditions, which don't often happen in real life. It's always better to go too big and have to restrict via a ball valve than to go too small and have to call a professional to repair the flood damage

Heres another link with some useful info. http://dslinux.dyndns.org/~denise/aquarium/DIYPlumbing/futureindex.html#drilling

Those are pretty easy numbers to hit and well within reason.

Man, thank you everyone for such a fast response!!!
This is just the info I needed. Planning a setup utilizing a Sequence Snapper, and I want to make sure I have enough flow to support the pump.

For flow at the bulkhead itself, sure. Take into account 90's, 45's, and runs of pipe and the numbers decrease a bit.

That has nothing to do with it. It does however effect pumping. Gravity and negetive pressure literaly sucks the water through the pipe. The numbers posted are more than doable and with proper durso tuning can easily be exceeded.

Yeah, easily exceeded. I have ~900gph being drained out of a 3/4". Totally surprised me.
