To pressure test by air or by water?
That is the question. As air pressure testing gathers momentum in several EU countries, take a closer look at some of the advantages and disadvantages of each methods. Hear from experts across the region and find out how to make your pressure testing more efficient and secure.

Reduces the risk of Legionella
In 2016, Legionnaires’ disease affected 1.4 out of every 100,000 EU citizens – that’s the highest figure ever observed for the EU. The disease is caused by Legionella bacteria, which can develop in pipelines and infect people through their showers.
An important measure against the bacteria is to avoid stagnant water. When executing a leak test with water, the bacteria can grow in the pipes if they are not thoroughly drained and dried. Air pressure testing completely eliminates the risk of Legionella because no water is used at all.
Secure and efficient process
With water pressure testing, it is easy to find a leaking fitting as it will clearly leak. However, the leaking water can become a source of water damage – electric installations can be ruined, new floors can be soaked, and walls can retain water and become mouldy or crack.
Air pressure testing completely eliminates the risk of water damage. And with no risk of puddles forming or water meeting electricity, air pressure testing can lead to a safer work environment. This makes it a preferred method of testing prefabricated installations.
Wise in all weather
During winter, the risks of pipe damage from freezing are rampant, especially during water pressure testing. When pipes burst, they can cause irreparable damage to the entire building site.
Air pressure testing is wise in all weather & winter, spring, summer or fall. It prevents slippery work areas, saves energy for heated water, and protects your pipes from any kind of weather-related damage. This means a leak and pressure test is no longer a bottleneck in the building process and full-season installation is possible.
