      just had a 40 minute phone conversation with robert

      probably has me confused with the other handsome plumbers

      as i don't shop at fergusons and i don't know the rep.

      robert went to the swap meet photo and the guy said it was the one eating ice cream. i think he was jealous

      i guess that's what happens when you get famous or infamous

      now 40 minutes talking ridgid tools would just get me started
      phoebe it is

          For once, I'll actually agree with you on something, propane does make for a more clean, evenly soldered joint...just takes all day.
          Acetylene & MAPP have a tendancy to "bake" the flux if you're not used to using them, or not paying attention. You can burn the flux and effectively create a dirty joint that won't take.
          I put the most intense part of the flame right on the fitting until it's almost hot enough to melt the solder, then back away just enough to maintain that temperature.
          As for solder, your also correct in my opinion, I use Silvabrite 95/5, other brands don't melt and flow as evenly...as long as I use this solder, it seems like I could use axle grease for flux and still get a decent joint.
          Ask ten plumbers how to solder, you get ten rituals...we all have our way.
          Part of mine is to heat the center of the fitting, not the pipe, because the flux chases the heat, the solder chases the flux.
          As for taking advice from sales reps, I liken that to taking medical advice from a pharmaceutical sales agent.
          Now you know why I come here.

            I take to heating the joint to right before the burnoff on the back side of the flame is turning green. IOW.....never seeing green.

              I'm sure we all have a little different method and I have not even tought about it in 20-years as it just seems natural anymore. That said the text book method is to heat the pipe first then the fitting then back to the pipe the distance of the fitting socket away from the socket and add solder.

                This is the exact opposite of my method

                Have I been doing it wrong for 25 years?

                  Here is a link to the CDA method which is very similar to our requirements listed in the UPC Installation Standards.

                      Just got in from fixing three four inch fitting leaks(existing).There were 16 four inch joints to be soldered,Two plumbers had one leak apiece,the fittings wear very loose tolerances.I've soldered plenty of large diameter pipe.The fittings are so tight sometimes we have to beat them on.I thought todays fittings going on so easy was a good sign untill I started soldering.The final product was gapped horribly.I would like to improve my capping skills.Anyone have any advice.

                        Yes we all call it silver soldering (erroneously) but I would say anything above 2" should be silver brazed. I had to do a 5" repair one night (13-story condo) and only had solder on my truck. Boy what a mess that was and it took two rolls of solder before I filled the thing up.

                          Of course I agree with Mark but for a different reason. Solder flows because of the capillary action so the tighter the fitting the better. Brazing works with capillary action but allows for much looser tolerences.
                          Buy cheap, buy twice.

                            I thought anything over 3" had to be brazed???

                            If I have a large gap, I tend to work the solder, hit it with flux, let it set about 30 seconds to cool, then hit it again with the torch, repeat if necessary, works great

                              Aciually Ben I think we agree for the same reason.

                                I use Bridgit solder. Saw a demonstration at a phcc trade show, seems like an excellant product. Supposedly it has good filling and capping capabilities. Manufactored by the Harris co. Would like to try thier flux but nobody carries it, so Everflux for now ( no complaints on the Everflux).
