      A neighbor walked by and probably thought I was high on something laying pvc fittings out in the street at 8:30 at night, and measuring the air in between them.



      When you guys talk about off sets, if this what your referring too?

      Would the center to center measurement times 1.5 work with a lay out like this?

      I tried and tried and couldn't get it to work out right.

        That 1.41 was on my mass plumbing test i tried using in the field with varying results I think it was no hub pipe that I could not get it to work with. but they may have been my error

          I'm sure my old boss would rather see chalk lines writing and math all over instead of all the couplings and scrap pipe he saw on my jobs.

                Lasco & Charlotte fitting? Might jack up your mojo for consistency Aaron.

                  Your sharp, there's only a few Charlotte fittings left on the truck, all new orders are Lasco fittings.

                    I don't put in a piece of pipe without at least a little math...elevation of tees compensateing for pitch,simple offsets,parallel offsets,rolling offsets,combination offsets,equi-spread offsets..setting manholes,figureing inverts..metric conversions(stupid govnt. prints)...the list goes on.

                    We had a guy we use to call "Lord of the Rings",or "Captain Coupling"..because of the piles of 1/4" wide pipe rings that would be laying around his work area...it was fun,we'd make olympic symbols with them,and glue them to his hardhat.

                    Plumbing (..err well new construction plumbing) is all about the math,then again,you really don't need to read a ruler to string out some pex....
