Water distillation is a micro version of the earth's water cycle. A water source is heated, converting pure water into vapor. Condensing this vapor yields drinkable water.
Condensation Coil
Attach a plastic hose of 3 feet or greater length to the pressure relief nozzle of a pressure cooker. This hose must be clean, a tight fit and made of a high temperature material.
Source Chamber
Half-fill the pressure cooker with your source water (well water, tap or even seawater). Attach the lid with the hose to the pressure cooker and heat to approximately 220 degrees F.
Collection Chamber
Place the loose end of the hose in a collecting pitcher. The condensed water vapor is distilled water.
For better condensing efficiency, place part of the condensing hose in a cool water bath.
Cleaning
After you have recovered a volume of distilled water equal to approximately 1/3 of the volume of the source water, remove heat from the pressure cooker. Let cool and then open the cooker and clean.
As you learn the efficiency of your distiller system, you will be able to gauge how much water you may distill without cooking your source chamber dry and possibly damaging your cooker.
