Been there done that and all that! This one is small with no way anybody will ever crawl it let alone access it, not even Larry.

We'd tented for years, but after a couple lions got us while camping out, we stay inside. We've done everything but put the insulation in for some guys and they still screw it up- not to mention when Larry the cable guy comes thru in a couple years with the newest cable type for some new Comm7R protocol and steps on my pipe. I don't care who ya are, that there pipe is busted. glc -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Bob Knight Sent: Tuesday, October 23, 2007 7:06 PM To: [email protected] Subject: RE: CPVC in Combustible Space with Insulation Scott and George, Around these here parts we commonly "tent" the insulation. This is a very standard practice within the local industry and has shown itself to be very effective over many years. The only draw back is when someone collapses the pocket and the insulation can then fill in around the piping. In this instance the "attic" space in question is very shallow with no room to move around in it. There should be no difficulties with this one.

If you put the CPVC in the insulation, above the ceiling, it will freeze.

"CPVC pipe and fittings are not intended to be installed in combustible concealed spaces where sprinklers are required by ANSI/NFPA 13, 13R, or 13D as applicable." "CPVC pipe and fittings are intended for use in areas where the maximum ambient temperature does not exceed 150°F. If the ambient temperature is expected to exceed this limitation, refer to the manufacturer's installation instructions for additional information on methods to reduce the pipe exposure temperatures. These pipe and fittings are not intended to be installed in outdoor applications." This would be similar to installing CPVC in a flat roof made of TJI's, and filled with Insul.
