set the reservoir up the same way. only one brass screen in the female barbed fitting will be needed. the rest is the same.
while waiting for the wet test to finish get an awl
and murder up the chocolate milk jugs
the milk jugs are gonna go inside the bucket sites and are a root guard. you won't need one for the reservoir. between the jugs, and the added brass screens, there should be no problems with the return lines becoming plugged by roots or other debris that collects in the system.
after the buckets pass the wet test the milk jugs will just press on to the inside of the union.
next we'll build a simple manifold for the return and start putting the system together.
back soon...
