550 GPH with 1" PVC overflow?

[rockethippo]

Will a 700 GPH pump (550 GPH with plumbing) be okay with a 1" PVC overflow? By the way, I'm new

Welcome to MFK!

A 1" pipe can flow 600 gph

Welcome to MFK!

A 1" pipe can flow 600 gph

but you have to take bends and other restrictions into consideration. If it's a DIY overflow I would make 2 1" ones to flow that much just to be safe.

plus i hear 2 overflows will prevent water surges in the main tank.

is this just by gravity or if you hook up a water pump to 1" returns will it be restricted to 600 gph aswell?

I'm new too

Anyway,

 

[Dr Joe]

Gravity.

I have a 1" overflow on my tank and a pump pushing 600 gph up a couple feet. I think the conversion brought it down to 500 GPH and my 1" overflow keeps up very well.

so if you have an overflow of 1 1/4" how many gallons per hour does that do? and what size pump do you need to keep up with it?
