I need to get a heating wire into an underground water pipe (plastic 1" NPT) that likes to freeze up when it's really cold outside.What would be a good way to get the wire in there securely without leaks?I'm envisioning some kind of a straight female-female coupling with a rubber gland on the side, where I can snake the cable in along the full length of the pipe, then caulk it into place.Received a quote from a pro, and it was north of $1000, which I'm not prepared to spend without looking at DIY alternatives.Thanks for any hints. via /r/DIY http://bit.ly/2U6TuYH
