SInce we have had record cold here my line from the house to the septic tank has an ice block of about 15 feet, as measured from the tank and from the cleanout. The tank is ok. The block is in the center of the line which must have a flat spot in it since it was not buried deep and my 8,100 pound truck has been driving across it for years. So, how to clear 15 feet of ice from a Schedule 40 sewer line? Yesterday we built a fire which burned 10 hours. All that happened is the ice block got bigger. Last couple of days have warmed above freezing and water from snow melt has percolated into the ground. It may have even entered the sewer line which may have cracked. Clearly, this spring, I will have to dig it up and examine the line and make needed changes.. In the meantime, any ideas on how to clear 15 feet of ice? One problem is no hot water here. So, would an electric power snake cut through 15 feet of ice? I have seen them used on roots and solid waste. Do not know about ice. Anyone have experience with this?
