Return for a 500 gallon

[david00061]

Will 2 1" return and 2 1.5" drain be enough for a 500 gallon tank size is 109x40x27. I want to add it to the center of tank

tank size down not matter.. what is the GPH of your pumps pushing into the tank?

With the returns i have a Iwaki 100rlt and a iwaki 70rlt (japan). I will ball back the 100rlt. I will be going straight up about 13 feet and over 2 feet. 1" pvc line

i think each 1 inch can handle 600 gph , and each 1.5 will handle around 800 gph if i'm not mistaken. so with the drains u have add it up too around 2800 gph. u might be pushing it close by using those two pumps as just iwaki 100 will be pushing 2000 gph and those things really move water. may i ask why are you using two pumps? one for chiller?

 

[david00061]

so a 1.5" will only handle 800 gph gravity fed?

 

[david00061]

how many gallons per hour will a 1.5" drain handle

 

[geaux xman]

1.5" drain will do about 1500gph.

theres a calculator on RC's homepage.
