There is a third parallel leg for c02 injection that is also merged....Had to think about this for a second because I did not understand the excessive plumbing.
Hm... OK 1 return pump and 2 canisters.
I have heard of people being tattoo happy and trigger happy but...
I couldn't come up with a more elegant way to DOUBLE the # of 1" intakes from 2-4, NOT clog the intake, and to feed in and out of a SINGLE pump.
Plus, each COMPONENT can be either shut off OR removed for maintenance, and the system could still be run. Well, as long as the component was not the pump itself
The 5 way cone distributors allowed me to merge the 4x1" inputs to a 2" pvc pipe that matched the pump connection directly to allow for optimal flow TO the pump. It also allowed me to split the pump OUTPUT for the 3 legs, a relief leg for unused flow and to reduce back pressure, as well as a capped off port to drain water quickly via the pump if need be. At least as far as the standpipes in the wiers.
The wiers themselves hid the extra over the wall 1" intakes.
Other outlets were over the wall in the back. This allowed me plenty of flow as well as control, since ball valves existed on ALL outputs. So, I could control how much flow went to each outlet as well.
