A hydrostatic test is a way, in which pressure vessels such as pipelines, plumbing, gas cylinders, boilers and fuel tanks etc can be tested for strength and leaks. The test involves filling the vessel or pipe system with a liquid, usually water, which may be dyed to aid in visual leak detection, and pressurisation of the vessel to the specified test pressure. Pressure tightness can be tested by shutting off the supply valve and observing whether there is a pressure loss. The location of a leak can be visually identified more easily if the water contains a colorant.

Fire Guard Installations uses a dedicated, mobile and specialised electric pump set that is designed to achieve high pressures (Low volume) of up to 2,500Kpa. After assessing the existing Hydrant or sprinkler system and pipe work for suitability for the test we connect this pump to the piping infrastructure and set the pressure to its pre-determined test pressure (1.5 x working pressure) for an hour whilst conducting video and photographic evidence of the test.

The initial assessment is critical in the process in order to calculate the designed working pressure and physical suitability of the system for this test. Our staff will pay particular attention to the seriousness of these parameters as over pressurisation will cause damage to the pipe work and joints.

After the test is completed the client receives a written report on the outcome.
