[TowerTalk] Questions about Irrigation Pipe for Verticals

[k1xx at cfl.rr.com]

Pat:
For 3" irrigation tubing, I used EMT conduit bought at a local 
electrical supply house.  At this time, I do not remember the exact 
size I used.  However, one of the standard sizes fits very nicely as a 
splice.  If you check, make sure you get the OD measurements since I 
think this was another potential ID/OD, pipe/tubing issue.  I also seem 
to remember the conduit coming in 8 foot lengths.
