 clearing conduit blockage

Well, winter is in the air, and I've just finished building my 'Murf tube' for the front of my FEL. (Thanks Murf!).

Now, I need to get power down my hill to run a small (300w) tank de-icer for the horses. When my excavator blasted for the water line, he left a shelf on the side of the trench for me to throw a conduit in (yet not have it at the same level or position as the water line in case we had to service either.).

In this trench, I put a 1" sch 40 grey PVC running from my garage down to where I need to put an exterior outlet. My plan was to pull a 12-2 with ground and put a single outlet down there, with the GFCI protection for it in the garage so the whole run is 'protected'. The run is about 270 feet.

Now, today I hooked up the shop vac, tied a small piece of baggie to a monofilimant line, and started to feed it up, as my electrican had done with the service feeder conduit (3"Wink yeah right.

The end at the house had been capped, but the end of the run that terminated outside was covered with duct tape, which had weathered and fallen off.

I'm convinced I have a partial blockage at around 150' or soo (guessing by how much string I was able to feed up). I tried clearing it with compressed air, etc. I finally glued on an elbow and started flooding the run with water from a garden hose (but our water pressure is low up on the hill). The water cleared out some gravel that appears to have gotten in during assembly.

Ideas for clearing it? I guess my alternative is going to be to try to measure the approximate length of the run until the string/bag hits the blockage and dig it up (which if I do, I'm going to put in an access/intermediate pull box like there should have been in the first place).
