    Flexible conduit for service line?
    I'm an owner-builder and am getting ready to run a service line to a house I'm building. Rather than deal with schedule 40, which doesn't allow much flex, I'd like to get some of the flexible conduit that the electric companies use. I'm figuring this is a 2 inch line. What is this material called and where might I get it?
    I prefer the flexible conduit because in the places where I might need turns, I'd rather have a gentle turn, than have to put in fittings with schedule 40 and have more drastic turns. Plus, the flexible conduit usually comes in long lengths, so it could be continuous, which would make it more water tight. It's to be buried.

    Sorry, but there is no flexible conduit for DB that I know of, the one I can find wants to be concrete encased.

    The flexible conduit you see, is it orange? That is Innerduct, widely used for tele-data, esp fiber.

    We do gradual bends with PVC Sch 40 all the time by digging gradual bends in the trench, and good planning.

    PVC joints when done properly actually weld the plastic together, so leaks should not happen. Keep in mind, all UG conduit can get water in it. Code even calls for a drain hole at low points. And all wire must be rated for wet locations.

    If what you have seen is rated for 600 volts, standard electrical rating for conduit, it should be available at your local electrical distributor.

    PVC is the way to go. You can heat with a Hot box, torch or any heat source. DON'T burn conduit. This will allow it to run in a smooth course, as if it were flexible, but then hardens when cooled.
    Some have put in their exhaust pipe to heat up. Don't know if I would recommend as there is a possibility of forgetting, melting or burning. Good Luck
