Hey everyone: I got my Mr. Moisture and I'm about to order my custom sized Hex tank. I will have the tank on a program of spraying, so I will have to have the tank drilled for a drainage hole. I can't remember how this is done. I remember reading about it before but now that I have everything, I can't remember where I read it. So could anyone point me to any info on everything I have to do to get a hole drilled(size, fittings to buy), the tubing connections back to the resevoir-just all the plumbing info I need. Sorry for the redundance. I appreciate your guidance again.
