Regarding the use of compression connected valves on copper lines,is it recommended, or neccesary to anneal the copper?


Thanks

    Back in the good ol' days...

    When I was in the plumbing biz, I never did, and I never had any issues with valves leaking or blowing apart. Technicaly speaking, it is against the code to anneal a pipe. Don't ask me how I know...

    Hi Mark, re: annealing of copper. The code issue is new to me however, my background is hvac/controls (service primarily) generally no inspections. Having said that,it has been a common practice to anneal in order to bend. Just never considered the codes in this regard. I like to do things by code with or without permits. Now I will check with an inspector here in the township. Thanks again.
    I mostly read here on the "wall" I am still interested enough to follow the threads,that is until the math questions and replys make my eyelids heavy!!

    Regards,Fred

    THat's how I got busted...

    I had a "situation" whereby I couldn't make do with conventional fitting angles without making the job look like crap, so I annealed the pipe, and BINGO, the inspector turned me down. I explained my situtaion to him, and he explained his situation to me, and I lost. Ended up tearing it out and coupling in the crappy looking method.

    This was under the UMC.

    Ya just never know...

    the thing that bothers me is

    that you can use soft copper according to most codes, but they squack over annealing copper which is what? heating the copper to take the temper out of it so you get what? soft copper. Oh well.

    Jeff: I agree with you regarding the annealing and in the case of refrig/ac the pressures are much higher,yet annealing is common to the trade. In my own home h/w baseboard system offsets were bent by the installer.
    Actually,the pictures that Hotrod post of the pipe and tubing bends, starts me thinking maybe he could use me for these jobs, ( a 64 year young apprentice)?

    regards Fred
