OK here's the deal I have this company call me up today to see if I could un-freeze a pipe for them. I don't see why not I told them. I am off to try to un freeze it for them tomorrow morning. Here is the tricky part it is a six inch pipe that only runs water through it. It is a staight shot not turns. It is also 190 feet long. What would you do to unfreeze it? I am thinking of a zero tip 180 degree water and rig a way to just send the tip and teh hose through all the way. Do you think that would work? Or do you think heating up the pipe from the outside would be best? Any Ideas are welcome to help make this job easier. Thanks in advance
