Water pipes are known to freeze over the cold winter months. If your water pipes are frozen NEVER use a blow torch, as your pipes will explode or crack. You should use a few hot water bottles, replacing them as needed to thaw out pipes safely with out cracking them. NEVER use any type of flamable heater under your home or in the basement to thaw pipes. An oil filled radiator would be a safe alternative to thawing pipes during the cold winter months.
