Ok, so I'm trying to do the math on my new build, and it's... a lot. Here's a couple thoughts I had:
Here's my questions: I'm assuming that 750 GPH is reasonable. 900 GPH is ideal, but 450 GPH is the bare floor.
My plan in my head is to use the 3/4" for a return. Should I actually use the first 1" as the main drain, second 1" as a return, and then use the 3/4" as the dry/wet emergency? This seems scary as the return flow could outpace the drain's ability to keep up.
If I go with the 3/4" as the return diameter, then am I going to run into issues hitting the 750GPH target?
I'm estimating that a VarioS 4 should be able to meet the 750 GPH target in either scenario...
Please, someone help my math. I've googled calculators for two days now. Thanks SO much in advance!
- 90 Gallon Bottom Drilled.
- 2x 1.75" holes (1" Bulkheads) - Source
- 1x 1.5" hole (3/4" Bulkheads)
- 22" linear drain space in the middle internal overflow
- 29 Gallon Sump
- I'll be running the overflow in a Herbie style
- PVC (Schedule 40)
- Gate Valve for the main drain so I can fine-tune
- MAX 62" of Length
- 56" of Lift
- 1x 90 degree
- 2x 45 degree
- Head Pressure should be around 9.3' ???
- VarioS 4 - 1056 MAX GPH - https://reefoctopus.com/product/rodc-pumps-varios/
