Conduit for low-voltage wiring is flooded


I buried some 3" conduit for a couple ethernet & coax runs to my garage last month. Pulled wire today and discovered that the conduit is somewhat flooded.

Pretty discouraged right now. It took a lot of work to dig & bury the conduit, not sure I'm up for digging it back out again.

To be clear, no high-voltage wiring will be run through it.. just coax, ethernet, and maybe an alarm wire. All the cable I have is shielded.

What options to I have, apart from giving up or digging the conduit back up and redoing?

Can I just pull some waterproof cabling through it and call it a day?

Underground conduit is considered to be a wet location and needs wet location listed cable regardless of whether it ever floods or not. So yes, wet location cable is what you want. I don't know what the cable types would be, but they have to go through underground conduit, so I'm sure somebody makes it.

Yeah, that's normal. Underground conduit is assumed to be wet. Even if it doesn't actually leak (and it usually does), condensation will eventually make it wet. Any cable you put in a buried conduit must be wet-location rated.

Will it hurt to use what I pulled for the time being?

Yes and No depending on the rating of the conductor you have there as long they are listed for wet location it is NOT a issue at all but dry location then yes you will have issue.

Just leave the conduit there it perfectally fine and yes you will see water in there from condesation which I have see it pretty often.

There is wet rated data cable and Coax cable etc.

Merci.
