personaly i would braze it, better safe then sorry


(Interesting. I remember seeing a post on here that said that a typical solder joint would be rated to about 3000 PSI, including safety factor.)
very true^

i have personally tested regular water supply soldered joints up to 800 psi, no leaks with a hydrostatic pressure test( hook it up and pump water in at high levels of pressure)

and no blow outs

so regular solder will hold well on 1/2" copper pipe at 150 psi? I'm getting a mixed input here.
