Water is a nearly colorless and odorless liquid and is vital for all known forms of life. It is the main constituent of oceans, rivers and lakes, and consists of two hydrogen atoms and an oxygen atom connected by covalent bonds.

Water is  a commonly used medium for hydrostatic tests due to its low costs and easy availability. It is used in many high pressure testing applications for burst testing as it is usually harmless to the system to be tested. To make leaks easier to see, often a red or fluorescent dye is added to the water.
