  • Kallista shower head thread

    I've recently moved into a house which has a lot of Kallista fixtures. The shower has what appears to be a Kallista for Town shower head which is plumbed from the wall up to the ceiling with a ~ 1 inch brushed platinum pipe which is equipped with a thread I can't quite figure out. This is the point at which you would screw on a shower head with standard 1/2 NPT thread.

    I got several new shower heads with the 1/2 NPT and they just barely start on the Kallista pipe. I tried cleaning it up with a 1/2 NPT die to no avail. I thought for a while that maybe they used a 1/2 straight pipe thread, but that doesn't seem right either.

    The thread measures 0.830 inch OD and seems to be 14 TPI. This is real close to the spec for 1/2 NPT but it just won't mate to it.

    Thoughts?

    thx

    Did Kalista use some weird thread to force you to buy their shower heads.

      Kallista = Kohler

      I wouldn't put it past a Kohler engineer to decide to change the thread pattern on a product that has worked fine for a hundred years.

      They probably want you to buy the $400 showerhead to match so you can't put the $12 one that Aunt Marge gave you last Christmas

        What would one change a Kallista brushed platinum shower head too that's an improvement?

        This sounds strange to me. And a pretty expensive showerarm is now f'ed up.

        3/4"-14 NPT.

          duh, 3/4 NPT not 1/2 NPT.

          The Kallista head was gone and a cheapo was installed.

          thx
