**Dear Hivers**

The two types of leak test

To avoid the degradation of the pipe networks and the risks of a leak, it is essential to carry out the leak test. There are two kinds of leak test. The first is the water tightness test and the second is the air tightness test.

water tight test: it allows to test the proper functioning of any type of pipe, whether an old or a new installation. The technique consists in evaluating the tightness of the pipes by means of water pressure. In all of the cases, test lasts 48 hours. This test facilitates the detection of sources of clogging or other damage in the pipes. the repair is essential. Thus, the purpose of the test is to guarantee the condition of the pipes and to optimize it.

The airtightness test: Like the watertightness test, an airtightness test also lasts 48 hours. It is carried out with an air pressure ranging from 0.5 to 1 bar. The objective of the test is always the same, it is to detect anomalies in the pipes, as well as its tightness. The principle of this air pressure technique is to prove the pressure difference between the atmosphere and the test. The airtightness test is carried out in three stages. The professional proceeds to the preliminary stage by generating the initial conditions of the pipes. Then it performs the pressure drop test, and finally data decryption.

Whether by means of air or water pressure, the leak test requires very precise work and trained professionals in the field. Before hiring a professional to test your pipes, you can seek expert advice on the most suitable test. The comparison of prices and the request for a quote are also to be recommended.

What equipment is used for a leak test?

Whether it is an air or water tightness test of pipe networks, professionals must perform it using high-performance equipment. There are materials specially designed to perform this type of test. These materials are made up of: a blower to ensure the pressurization of the pipes, an automatic pilot, a digital sensor, software for managing the results of the test, as well as an element for converting energy. There is also the Waston and the Wiki respecting the NF EN 1610 standard. The materials differ according to the manufacturer and the type of the leak test.
