Good question...I'm pretty ignorant too about this....anyone?

Couldn't you add ball valves to all the returns, and dial the ones closest to the return more closed, with the ones at the end fully open? Tweak until you get even flow? I've also wondered about this, and it's the only solution I can work my mind around.

Thats what I was thinking as well. However of every photo I've seen, nobody has used ball valves or anything, they all look like Harveys setup.

No ball ball valves required if you use a pressure rated pump.

Hey Danny, can you explain this? I'm a pressure rated pump dummy
