    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.

    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.

    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.

    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.

    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 .

    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.......

    I know, I know.... I didn't use copper

    Maybe I'll find someone with a plastic welder and try that.... ;-)

    Artic Blaster

    What is it in detail

    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.
