Mike It's been a while since we've talked. I have come across some interesting stuff lately regarding multipurpose systems and wanted to run it by you.
I have plumbers and the mfg rep from Uponor telling me that it is perfectly legal and acceptable to install a normal domestic plumbing system using non listed PEX pipe and non UL listed (1821) fittings and tie it into the sprinkler heads. They say the way they read the code (they haven't been able to identify the code number yet) as long as the fitting with the sprinkler is listed, the 'T' off the plumbing system is listed, and the PEX in between is listed they are legal and conforming to code. This seems wrong to me. It defeats the purpose of requiring the fire sprinkler system to be composed of UL 1821 listed components if 95% of the pipe and fittings between the incoming water and the sprinkler system is not listed for fire.
