    I need to solder a 3/4 copper pipe that will run at about 50 PSI @ 180 deg F.

    It is my understanding that your average homeowners solder for copper pipe will not work.

    I know how to silver flos? (done it a few times) but dont know what the name of the rod I was using is called. Some type of silver?

    Can someone point me in the right direction here please?

    Thanks!!!!

    That is within the realm of 50/50 or 95/5 plumbers solder used on hot water in homes and businesses every day.

    Stay-Brite is another solder that is the "same rolled" as 95/5 sold but rated for higher temps and pressures...flows the same...same flux clean pipes(flux)and give the solder a quick slide thru the sandpaper and dip it into the flux prior to hitting the pipe!

    LOL..
    "Good" ?? Umm.. its not rocket science eh? I didn't find it difficult to understand.. It was much more like welding that soldering. Now welding I'm good at I've done more welding than I can remember.

    Thanks for the info.. This site rocks!

    The 50 psi is for the other side of the heat exchanger.
