good comprehensive info. the drop link, is that a vertical dropped down section of pipe with a drain plug at the bottom plumbed into the system to drain water? who sells the toilet paper filter? I'd like to try it just for the novelty!
Drip leg can be plumbed right in line, deploying several if you want. Its a Galv T fitting that has your air passing through it side to side, but the bottom part will have a nipple hung off of it (10" should be fine). Ive thrown a union on the end of a nipple ( a union that i speak of here would be female by female thread) and buy a ball valve , then insert a press lock fitting to run a drain line to a container or outside.
