you need
  • - cloths and rags;
  • - boiling;
  • - capacity for water heating;
  • - a hose or a long, thin tube;
  • - a double boiler or pressure vessel;
  • - fitting for fixing the hose.
If you know the location of the ice caps and you have access to the pipeline (that is, it is on the street or in a basement, but not buried in the ground), try the following method.Distribute to the pipe at the location of ice and cloth rags and start to pour boiling water over them.The procedure should be performed at the tap is open - once the water will go, stop and turn off.
Prepare a large enough container and heat it in the water.In the frozen plastic pipe direct the hose or a thin long tube, one end of which is connected to the
container with boiling water.
Note: if you have disassembled part of the water supply system, make sure that you had the opportunity to block the water (for example, using a crane) after an ice plug is melted.
Connect the hose (or tube) and begin to pump the hot water in the pipe.Do not forget to close a large enough capacity, for example, desyatilitrovoe bucket, since water will be poured back pretty quickly.
As the melting of ice jams push the hose further into the pipe.Proceed as follows: turn on the pump, wait until the bucket is full, then turn off the pump, pour the water and promote a hose.Repeat the cycle as long as the pipe is flowing out of the water - at this moment quickly pull out the hose and turn off the water with a crane.
Instead of boiling water, try using hot steam - this will save you from the problems with periodic pouring of water, in addition, the steam temperature is higher than the water temperature.To do this, take an autoclave and put on the hose fitting from the gas welding (pressure-resistant).
Pour a bucket of water into the autoclave and put on a plate, push the hose into the pipe to the maximum possible length.When the water boils, the steam pressure will go to an ice jam and melt it.Instead, the autoclave can use a double boiler, but keep in mind that the water in it ends quickly, so you need all the time to monitor the process and add new water.
