  • soldering ball valves

    how do you guys solder ball valves- open, closed, or half way

    Re: soldering ball valves

    They used to say that soldering the valve in the closed position would lessen any seat damage so I've done it that way out of habit for years.

      I do it closed in the off chance that solder might drip into the opened valve.
      I've heard arguments for both ways though...not sure if it matters, barring the small chance of solder dripping down a vertical valve.

        done it both ways, as well told by old timers closed, but let experiences rule the day, seen others over solder and others burn joints. now when i use my jet sweats open rules the day,good question makes you realize you can sometimes forget as much as you know{zen riddle}

          I was taught open because any water trapped in the ball during soldering can turn into steam raising the pressure which causes damage.

            I was told closed.Now after 100's of valves either way I call bulls**t

            Just did 3,1-1/2 and 1,1-1/4 today three open for presure relief one closed to keep an eye on alignment.

              Dunno if I speak fer you guys, but I'd really like to hear from someone that has a solid reason for doing it either way.
              The only reason I buy the solder dripping thing is that I have had solder roll into a diverter stem on a shower valve and cause it to stick.

                ive gotten a pretty good burn by soldering one closed and opening it when i was done the steam build up got me.

                  I had one blow when sweating in the closed position, so I can vouch for that happening. Either way is fine though, for the most part.

                  I like sweating with it closed so I don't accidentally torch the handle, and the handle doesn't block my vision.

                    Re: soldering ball valves

                    I was taught to solder all valves in the open position. Since ball valves came out much later, I don't know what they teach, but I still solder all valves in the open position. IIRC, it has something to do with the heat not traveling as far up the pipe. But it's been quite a few years.

                      On stops I don't think there's any argument...always open.
                      The seals melt when closed.
                      Ball valves are a different horse.

                        Re: soldering ball valves

                        gate valves closed.

                        ball valves open. actually slightly in a 95% open. i like a little close to keep any water or steam from getting trapped in the seat/ ball area. this of course is on repair work with water.

                        i forgot, i propress a lot more than i solder valves now. in fact i don't even worry if the water is running

                          Re: soldering ball valves

                          I solder ball valves fully open, never closed.

                            Am I to understand you don't take the gate out when soldering gate valves? Did this cause any negative effects?

                              ben, the gate has to be in the valve to prevent any solder from getting into the cavity and preventing the valve from closing. especially when soldering in a vertical position.

                              a globe valve/ washer needs to remain open to prevent heat damage to the rubber washer. this is very common on tub/shower screwdriver stops and soldered angle stops.

                              do you actually remove your gates?
