Quick plumbing question

[ReeferBen]

I have a 110 gal tank, right now the sump is under the tank. It has a center overflow (reef ready tank), with two returns and two drains. The overflow bulkheads are slip with a piece of thin wall 1" pvc slipped in with a flex hose going to my sump. The flex hose slips over the 1" pvc on the sump and on the bulkhead and it held on by a clamp.

I am moving the sump from the stand to the basement. I have to run the drain lines 12' vertically and 10' down. If I just run two 1" PVC pipes up from the sump (both drains, I already ran my return lines) to the tank and slip the flex hose on the pvc with clamps will I be getting atleast 1000gph returning to the sump? If I go to 1 1/4" PVC would that be able to increase the amount returning even though the water has to go through a bulkhead that would need a 1" to 1.25" adapter to increase the return pipe size?

Sorry sounded like a simple fast question in my mind lol, TIA.

The 1" bulkheads are going to limit your flow, but I would still increase your plumbing size when doing a run that far. Just an added layer of protection if one of the lines gets partially plugged up. Both 1" and 1 1/4" PVC are cheap, so it won't cost you much more to increase the size.

a 1" pvc overflow is capable of handling 960gph

#1 FlexPVC®.com PVC presents GPM/GPH Flow based on PVC Pipe Size, ie, How much water can flow through Sch 40 Pvc Pipe Size 1/2" 3/4" 1" 1.5" 2" 2.5" 3" 4" 6"

Flex PVC is not meant to be clamped and will more than likely leak. Just use a 1" coupling couple if you're going to go with the 1" flex or an 1 1/4" coupling with a 1 1/4"X1" reducer bushing and prime and glue just like you would with regular pvc. Best of luck.
