Plus the PVC or conduit will provide physical protection for the

shakes my head

Water and gas lines that cross streets in PEX have no "conduit".

more likely someone someday might install a post or try to plant a
bush PVC is cheap protection from future troubles.

I agree completely.... I had thought it a good idea to put the PEX
inside
of some cheap Sched 80 PVC for the same reason, but not make
the joint connections -- just slip the PVC over the PEX and walk
it through---- just to use it for the added protection when I stick a
shovel
in the ground to plant a bush in the wrong place....

I routinely use that technique when burying UF electric for the same
reason....-- it's a pain to have to do splicing to replace a nick in
an
underground electrical cable....

I don't know whether code allows it or not -- I think it does --- but
it's a great idea nevertheless and gives me great peace of mind...

Your 3 inch conduit could be that cheap drainpipe stuff, and you could
pull stuff thru it in the future. A very good idea in my opinion, but
maybe
a little costly......I guess it depends on the length...
