I am just finishing up one of those. I had to supply them with PE
stamped drawings and coordinate it with their manufacturing process.
What they shipped (18 sections for 9 apartments) was some 1" CPVC
thrown into the truss space and and "supported" with strapping tape
stapled to the truss. Then the whole mess was covered with sheetrock
with a couple of holes. Not even close. What we did was ask for the
plans the factory installed to and then get a rep out there to verify
that it is no good. The factory is now paying to have a new system
installed with CPVC pipe and Decosheild. I started the project in Dec
2005 and installation is going to start in the next week or two.
Welllllll this afternoon I loooked at a "pre-built" duplex shipped
in on 12 trailers to make a 2-unit 3 story building..... ALL piped
in "WIRSBO-PEX-a Tubing"... MAX Pressure of 160PSI @ 73.4 Degrees F.
All piping is 1" size. NOT like in the hydraulic calcs. the
manufacturer supplied. Now to convince the owner the finished walls
and ceilings have to be ripped apart to install a Sprinkler system
since the AHJ is going to require one.
