That sounds possible, but how do I know it's not a soldered connection? I've seen sillcocks with hex flats that can be soldered as well.

I would first remove the paint to determine if I could see any sign of threads on the pipe. If no threads are then visible the fitting is either soldered or the threads are called - (buried) - by some Bubba. If necessary you could go as far as removing about an 1/8 or 3/16 inch of a hex flat to see if threads were then visible.

Mr. Bill, did you ever get that anti-siphon hose bib off and how did you do it? I have the EXACT same situation. I have tried brute force and PB Blaster. Did not try heat, because my house has PEX plumbing. I have removed ball joints from 40 yr. old Chevy pickups, but this thing is driving me crazy. Especially when you go to ACE hardware or Home Depot and try to tell them it has NO set screw and they tell you they are 100% sure it does. I am half a mind to saw that @$%^&*% thing off long ways(up & down) in 2 halves just to show it to all the folks that are calling me crazy. Thanks very much for any update.

Home depot was my recession job. Some of the advice I heard given was beyond pathetic. What was worse my immediate supervisor reprimanded me for correcting a fellow associate in front of a customer. Who was telling the gentleman that it would be fine to screw through OSB into the side of another piece of OSB for garage cabinets. Then management got all pissed off when I tried to educate my coworkers about the difference between materials a d best practices. He claimed they had a training program in place for those things. 2 weeks later they gave me a 22¢ an hour raise (which didn't match inflation) that ended my employment with the orange morons. Don't get pushed around by an apron. Just look at them with a straight face and ask if he has 2" nipples
