I've never done conduit in a whole house system though. Just single rooms. I'm pretty sure code doesn't allow for more than 180deg of turns before you provide access and while that doesn't aply to low voltage where I am, any more and friction will prevent a good pull. What are you using for longer runs that may require multiple turns? Hidden access? Access via future drywall repair? I've never tried the Carlon Flexible conduit and I think this could be a good candidate. How's that for friction on the inside?
