Time to tap the brain trust here: I have an exterior sump pump pit for the two sump pumps (plus backup) that handle my foundation drains (no sewer and daylight is 10 feet up). It's 24" in diameter and over 10' deep. Since the cords on the pumps don't even reach to the top of the sump, I remove the plug on the end of the cord, extend it a couple feet with SJOOW cable, and install watertight plugs that plug into mating watertight cord mounted receptacles. All of this is inside the sump. From there, SJOOW cable runs through PVC conduit from the sump to the inside of my basement. On the ends are standard AC Plugs that plug into alarmed GFCI outlets. That's the part I'm unsure about. Essentially have heavy duty extension cords running from the inside to the outside. They are only 6' long, tops. I'm about to pull a permit for some other electrical work right next to this stuff, and I don't want to get any grief from the inspector if the above arrangement isn't OK, code-wise.

I have to pull multiple cat6 cables thru a 200ft underground conduit and then in the worst case up 5 floors. The conduit is four inches, but, due to the length of the run and presumably the hard 90s it makes, even 6 cables cannot be pulled at the same time. It's beginning to become apparent that another conduit needs to be run, but I still haven't use this conduit to some extent. I have cable lubricant, I'm buying a second and third box of pull string to run multiple fishing lines. Are there anything else I can do? I've also tried taping the first 50 feet or so to keep it thinner and reduce friction, but that appears to have been counterproductive. Any help is much appreciated. Presently, I've pulled out 6 cables after almost 300 feet when it just stopped moving, and I'm down to trying 2 at a time.
