I'm no soil scientist, but I've buried some socked tile in my time and I don't buy it.
Once the socked tile is covered in coarse gravel, with 1 or 2 layers of finer gravel on top of that, I don't see how enough clay migrates down to clog the sock. Clay soils are very cohesive, if that's the right word, and once compacted, it's difficult to believe enough particles would seperate off to clog the sock.
Other particulates could prove a problem, if say lime-stone grit was washing into the trench, but not clay.
Maybe some wall guys-- Bill Schwab, bjr, pennscapes, Stonehenge-- could jump in here?
