How to Make Steam-Distilled Water Using a Pressure Cooker

Without water, people can die in as few as three days. Water is vital to the proper function of the human body, so access to clean water is important. In certain circumstances, such as natural disasters or water main breaks, clean water may be unavailable; knowing how to distill water can be a life saver. Steam distillation is a simple way to purify water that you can do at home using a pressure cooker.

Instructions

• 1

  Remove the weight from the lid of the pressure cooker and attach the tube to the pressure cooker's steam outlet.

• 2

  Place the other two pots near the pressure cooker.

• 3

  Fill the pressure cooker and the second pot with unheated water and coil a significant length of the tube in the second pot. Allow the end of the tube to empty into the third, empty pot.

• 4

  Turn on the pressure cooker and bring the water to a low boil. Steam will flow through the steam outlet into the tube and be cooled back to water as it passes through the second pot. The water in the third pot will be distilled and free from impurities.

• 5

  Turn off the pressure cooker before all the water has boiled away to prevent equipment damage and to keep the steam-distilled water as pure as possible.
