    Hey need some help !

    Looking at bidding re pipe of lg. Commc. Factory with 40' high ceiling roof line

    Everthing has to be raised hauled up to this working level

    trying to get a cost comparison between

    silver solder (braze) 2" and 3" pipe and

    joints versus propress same pipe and

    fittings,

    already have torch and rosebuds for

    silver versus buying new propress

    jerry at 40' i would want to get in and get out

    last thing i want to do is silver/ braze large joints and try to maneuver in the air. not to mention fire sprinklers, flux and potentially leaks

    depending on the quantity of work you need to do, renting might be a better option.

    i know someone with 7 machines and would probably rent one to you at a reasonable cost

    what is the scope of the project. footage, fittings and working environment?

      Jerry are you still in Houston???IF so, How was the Masters exam I go may 11th?? If 40 ft was all there was to it and there wasn't any fire sprinklers to worry with I would probaly just silphos and be done.Just my 2 cents.

        The supply house will more than likely let you borrow the propress machine due to the fact you've just spent thousands buying material from them.They can get a demo from a rep.

          this is a existing 3" galv. Water main that

          then reduces to 2" galv. That needs to be

          repiped with copper,

          2" and over to be silver soldered by code

          below 2" regular solder

          what is most cost effective way working

          in a overhead area

          already have full torch capability to

          silver solder,

          but time wise plus material cost

          which way is best any cost numbers

          on 3" and 2" propress fittings from

          ferguson ?

            Jerry,

            I think it's a no brainer. You ProPress this job. (Did you think about victaulic? Just spitballing here.) Less chance of leaks, and the joints take less time. Although your costs go up.

            I don't know about in Houston, but up here there's a plumbing wholesale house that will rent a propress unit. $40 a day. Maybe it's the same down South there.

            On the off chance that you're an adventuresome soul...
            Check this out. I don't think it's legal here in Minnesota, and have never seen it in person but it might be just the ticket for your job. http://www.streamtechsystem.com/ Maybe you can administrative approval to try it, and have the Rep "guarantee" it won't fail.

              thanks for the link geno

              interesting concept. looks like a propress fitting.

              problem i see is that the glue has a 20 minute working time and needs 3 hours for testing.

              i don't see how you could not bump or move the system for 3 hours.

              also for service work, no way to keep the water out of it.

              give me propress and i can work in water and be done in 5 seconds

                  Without seeing the job it's hard to know about the space involved, but maybe they can leave the current piping in place and run a new main next to the old one with takeoffs where they need to be. Later do the runs after the old main is out.

                  There may be other considerations, such as the plant can not be without water for longer than "X" period of time. In which case the ProPress is, again, the way to go. What's faster than ProPress?

                  As I'm sure you're well aware, often in commercial settings the cost of material is down on the list of considerations. "Uptime" may be far more critical. Going back twice (preinstalling a new water main) may be cost prohibitive too.

                  As for service work, I wonder how much water the "O-ring" will hold back?

                  Personally I don't think I would trust something like the Mueller-3M system unless it had a TON of documentation and history. Although... 3M came up with an adhesive that goes between sections of airplanes. Yep. They glue the aluminum sections of some airline components together. They put the sections in a huge vacuum chamber, and there may be some heat involved but I don't recall exactly. Anyway, the aluminum will rip itself apart before the glue joint fails. Who knows, maybe this will be something similar in adhesive quality.

                    Few fittings. Torch, torch, torch.

                    Many fittings. Press, press, press.
