How the parts in high pressure aeroponics system are put and work together

[kosmonaut89]

Hello!
I'm wondering how the parts in HPA are connected . How does the schematics look?
I've read: http://thehotpepper....ure-aeroponics/
but I'm not sure if I understand it.

Where does the water enter to begin with? As far as I understand the water comes through the solenoid (3) and let water into the pipes which is then pressurized by the pump into the accumulator. When the accumulator lets off water it goes through the (2) pressure relief valve but what mechanism makes it not go back to the white pipes??

Thanks
