And in the really good days, when no one would want to steal our work, this stuff was threaded. Flanged-thread 90's, all the stuff you couldn't expedite, let alone find, these days. I believe you'll find standard couplings are listed for dry-pipe use, just that they recommend the tri-seals now. Chk the listing of your coupling of choice for the answer. glc -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Dewayne Martinez Sent: Monday, December 01, 2008 9:36 AM To: [email protected] Subject: manual dry standpipes - grv cplgs Is it alright to use standard grv cplgs on a manual dry standpipe for a parking garage instead of the "tri-seal" type made by Tyco? I have a fitter that is worried that water will be left in the std cplg after testing that may freeze. What did they do in the old days before Tri-seal cplgs?
