[Double Venom]

Jery,
We built all our lines with 1" black pipe, nipple off for the dryer then run the dryer off of that. The new shop will most likely be 1" schd. 90 plastic! Cheap, don't need to be a plumber and easy to make any "drops" that you might need.

If you really want to be cool, at the end put in (make) a long sideways "T". The air will come in from the top of the little leg, remember I said sideways, the dryer will come off the long leg, and the bottom you can put on a "faucet" if you will. Then when you think your lines have water in them, just open the faucet to drain!

DV...wish I kew how to use Windows drawing program better!
