copper flex in main line


is there any code violation if there is a short (18") piece of flex copper pipe (one generally sold for connecting water heaters) in the main supply - downstream of the main shutoff but before the supply splits up to for distribution?

i had to rearrange some piping and the final connection will be lot easier with a flex rather than trying to align with multiple elbows
thanks

Only place I can use flex of any kind is at fixtures- after the shut off valves. This includes water heaters.

Some places even require hard pipe to water heaters.
Flex on main piping is frowned on

That's a question for your inspector.
Would be no problem here, but that does not count.

That changes everything---depending on the code in your area, pex could be used for all of the run ,or just a section----

the new houses in my neighborhood have all (or most) pex...so i think it is legal.. the dilemma i have is that all my piping is currently copper so an 18' pex section would look odd.
