Okay so if anybody has been following my new adventure lately I decided to use a Quiteone 4000 High head for my overflow/sump.
I just picked up a Little Giant 4-MDQX-SC which is a circulation pump, which is rated at 1225@3' and 1080@6'. I"m not 100% sure what size piping to run to get it into my tank.
The input and outputs are 1" so I figured I'll run 1" PVC
pipe from the overflow box or from the tank and run that down to the pump. For the output I was thinking of 1" pipe run up to the top of the tank, then T off into two 3/4" pipes one going to the left side of the tank, one going to the right side. Then each 3/4" pipe would split off into two 1/2" pipe. One 1/2" would go in at the top of the tank and the other at the bottome on each side of the tank.
Does that make sence and would this work? I was told that these pumps should not be throttled back with a ball vavle, will the reduction in the piping be okay that I'm planning on? I was also thinking of using a SQWD like Logan suggested but that might be too much flow comming out of just two returns at a time?
