Flooded: TW in conduit

[fmtjfw]

I have a building that was flooded. The branch circuits are TW in conduit.

Would you replace the TW with THHN/THWN?

Would you add grounding conductor on the chance the conduit joints (some sort of connector with no visible set screw or compression nuts (Chinese fingers for all I know?)) have been compromised?

Would you replace the switches and receptacles that had been under water?

Might as well rip it all out and start over if you start doing all the work you are asking about.

TW is rated for wet locations, so I would not be worried about it.

I would not be real worried about the conduit as an EGC either.

The switches and receptacles probably should be replaced if they were actually under water.

having said this, if the building flooded, there is a lot of gutting and rebuilding that would likely be going on that might make it practical and economical to just rip it out and start over.

Structure is fine, brick outside walls and tile "bricks" inside. Fine silt in electrical boxes and on devices (and in panel).

I see no reason to redo boxes or conduit.
