ok, heres a basic design that should work well...
your going to want to make two sub-assemblies like this:
and then assemble the two sub-assemblies like this.....
this is if you are using a 3" diameter barrel that is 3' long.......
as for a valve, ide suggest looking into a modded sprinkler valve, a ball valve will work just fine, however a sprinkler valve will give you more consistent results.
Why are you showing 2 T's in the first diagram, but only 2 in the second?
and is it necessary to connect both ends to each other?
second, i might concider the sprinkelr valve, but im trying to avoid using anything automatic. Sides, to they even make a 1" sprinkler valve?
