--- title: Water Added Machine --- Celebrating 30 Years of Pipeline Excellence #### Pressure Testing Equipment # Water Added Machine ![gauge-black](https://ahs-pi.co.uk/hubfs/Icons/gauge-black.svg) #### Overview ### The Water Added Machine is an innovative piece of equipment designed by AHS specifically for Type I pressure testing. It is used to accurately control and monitor the addition of water to the pipeline during testing. The machine ensures that the system test pressure (STP) is precisely maintained by adding water in small and controlled increments. This precise control allows for far more accurate testing than the traditional methodology allows.
