Conduit in parking garages?

[jusme123]

We'll have to agree to disagree on that one. I've personally strapped PVC every two feet and still seen it sag. Only like it for underground...

...if strapped that close it shouldn't sag , especially if pvc straps are used and expansions where required.

Rigid conduit rust after time , regardless what you do, especially at couplings (at least in North East).
