    frozzen pipe

    You can rent a jet water snake at most rental places. It will fit down the black pipe you have. Just hook it up to hot water. The standard jet snake pushes a jet at about 1000psi. That will work for sure. I've done this my self more than once. Good luck.......

    Arctic Blaster

    Just ordered one! Thanks for the advice! For $500, including shipping, this seems like a great unit. Simple design, no moving parts, and includes 2 50' coils of braided tubing... 1/4" & 3/8". Also, it doesn't require a connection to a water supply... which is a plus when it is the main line you are trying to thaw. Check it out at

    The freeze is 15 feet away from the building foundation, under 6 feet of earth. I used an electricians fish tape to probe down the line to measure how far away from the building the freeze starts.

    Why Not

    Purchase a roll of the smallest pex tubing you can, hook it up to the hot water heater with a backflow preventer and a small pump. Then fish it down the line. Turn on the pump when you get to the blockage. This should eat right thru a frozen line. I would suggest turning off the main unless your reeeeaaaaly quick .

    How do I thaw a plastic underground water pipe?

    Here in Northern Minnesota, we have had sub zero weather with no snow this year. Many people are experiencing problems with frozen water and septic pipes. I need to thaw a 1" black plastic water line that is burried 6 feet below ground and is 30' long. I know some use steamers, but I can't find a source for them. Any suggestions would be apprecieated.

    We've had great luck thawing these types of lines out by pumping hot water into them.We made up a rig that uses a propane burner,a transfer pump, and 1/4" copper tube. To Learn More About This Contractor, Click Here to Visit Their Ad in "Find A Contractor"

    frozen pipe

    Might try a hot water flush, fish down the pipe with a smaller sized 3/4 plastic pipe. You can get the pipe at an Irrigation supply house.

    Buy a Arctic Blaster

    Its so simple it will blow your mind , and it will only take a half a gallon of water and 15 minutes to thaw that line.
