    Air chambers in N.Y.???????????? P.S. I'm not being a smart A$$ for once.
    Dude are you hitting the sauce? Your posts don't make any sense? Have you been to the doctor lately? I'm being serious. We must take care of the elderly

      N.Y. What's Your problem DUDE?
      I can build anything You want , if you draw a picture of it , on the back of a big enough check .

        Re: wood framing and shrinkage

        this building is one i do work at. but not this project. i was asked to inspect this before the work is done to advise them of my findings.

        there are no air chambers on any of this work. in all the years of large scale new construction worked on, i can count on 1 hand the amount of air chambers we ever installed. hammer arrestors are a different story.

        in the old buildings/ homes, i do come across air chambers on water and drip legs on gas.

        remember out here we don't install air chambers, drip legs on gas, and we do use both black and gal. on gas

        truthfully i do believe that pex will overtake copper in the coming years.

              we've had discussions over the past few months talking about double drilling and wood shrinkage in new building construction.

              here are a couple of photos that show a shower ruff from 1987 on a 4 story wood framed building built over a 12'' thick raised slab/ garage.

              keep in mind that this is type m 3/4'' copper and is from the 3rd. floor that is under renovation.

              the reason why the 1/2'' hot, 3/4'' cold risers are bowed is because the shower valve had no expansion joints/ flex to allow for settling as the wood shrunk from all 4 levels. the valve being tiled into the wall had nowhere to move. if it had an expansion joint/ flex line, it would have allowed the pipe to move separate of the valve being dragged down.

              when i did new construction in this same city, we were required to double drill all the horizontal holes and also use a flex copper connector on the tub/ shower valves.

              a concrete and steel studded building would have not shrunk.

              rick.

              Could you elaborate on the definition of double drilling. Maybe I missed it.

              Thanks.

                    on any horizontal line that run through a stud, you whould be required to drill a hole followed by another hole just above it. this would allow for an oval stacked hole that the pipe would sit on the bottom hole and the upper hole would allow for movement/ shrinkage without putting any stress on the piping.

                      Rick, why not just drill a 1" hole for 1/2" horizontal runs? Wouldn't this accomplish the same thing faster?

                        We drill 1-3/8 then use isolators for 1/2,3/4 and 1".

                          this is from a 4 story building built in 1991 wood framed. owner complaining of excessive noise when other units above or below would run their shower.

                          the building actually shrunk so much to shear and bend the piping. i was able to cut it back and restore the proper alignment.

                          notice that the line had been repaired 2 times already due to leaks.

                          i cut out the pipe on the 2nd. floor unit and replaced with propress. also installed acoustoclamps to isolate the pipe from the framing as recommended by the acoustical engineer they brought in to consult about the noise. for $25,000 a month, i guess he deserves to sleep without being awoke to the sound of a shower in the stack

                          i was able to attach to the risers in the first floor unit. the third floor was just remodeled and they were not going to let me open it up.

                          the engineer will be taking sound readings tomorrow. so far without drywall or insulation, it sounds much better.

                          rick.
