Here the city uses it for runs from the water main into the house.  They 
use the same type of equipment to lay gas lines. The water line comes in 
3/4", 1", 1 1/4", and 1 1/2". I don't know if it comes any larger or 
not.  You don't often see it, but most hardware stores, and even big box 
stores have it...some where.  Shop around as I'm sure this is one of 
those items with a price that varies widely. It's sorta like the PVC 
conduit, but softer and a LOT *longer*.  It's a good idea to work with 
it on warm or even hot days.  It tends to flatten out a bit, 
particularly in the larger sizes when you unroll it.  It comes in rolls 
up to 1000'. Great stuff for network cable runs as well as small coax 
such as RG-6 and 8X.

Just ask for a coil of 1" water line. The larger sizes might be harder 
to find.

Oh! I drop a mothball or two into the junction boxes on each end.  Keeps 
the creepy crawlers out. It the larger, fur covered ones get in, it just 
keeps my cat fed and he's one big cat!

Personally I don't like the corrugated tile, but maybe that's just 
because after having a farm for 50 plus years I've kinda grown to 
dislike working with the stuff although the current crop stands up 
better than the old tile.

And John is right, the vacuum and mouse is a good way to get a messenger 
line into a fairly long run...as long as it doesn't make any sharp 
turns.  Some one suggested using 2 45's instead of a 90 which is what I 
do with large and small conduit.  It just makes life so much easier.
