Weekend (well-FT, I’m retired) worrier here.
I’m pulling wire to an outbuilding through PVC conduit installed over ten years ago and recently extended to the building. I just duct-taped the buried end of the conduit when my son ran it under the sidewalk behind the house, and it’s got water in it.
It won’t be a hard pull – four #8 wires in 1″ conduit over a 32 foot run – but should I run a rag through the conduit a few times to clear the water and dirt?

Water in underground conduit is expected. You can suck the excess water out with a shop vac while you are sucking a pull string through If you think there is dirt in there I would pull a rag through to get as much out as I could. Then suck some lube like "Yellow 77" through and stuff in the wire.
I've wondered about this.... considering that water will eventually be in there due to condensation, should you use something like NMWU or can you get away with regular NMD?
