Hi All, I am plumbing my new 7’ - 350g aquarium, which contains (2) 30” overflows with 3 holes each for a bean animal setup for each. So I have (4) 1” drains (plus two emergency overflows). reducing down to a single 2” main drain (I only have space fo a single drain to the tank room). Here is the back where the external overflows are
This is the right overflow showing the drain lines (emergency line is in the middle) dumping into the 2” main drain to the sump.
My return pumps are two Iwaki 70s (1536gph x 2 = 3072gph) with two 1” returns splitting to (4) 3/4” lock line returns with duckbills. My question is if I have 4 3/4” returns, will (4) 1” returns reduced down to a 2” main drain be able to handle the draining capacity? I read a 1” pipe can take 2,200 gph, so 2 pipes = 4,400 near peak and a 2” pipe takes 7650gph so it should take it, but not sure about the pressure and if I need to go to a 3” main drain? Let me know your thoughts. Thanks
