We do it all the time. You can use a 'mouse' designed for the specific
purpose made from foam rubber, or you can take light string (like 90# kite
string) and tie a plastic baggie like a bread bag on it. It takes some
practice to get the right size, but it works well for several hundred feet
assuming a good shop vac and tight conduit. When that doesn't work, we do
almost the same thing with a high volume compressor and blow the string
through (and the water out if needed.
