Method of leak detection

On completion of the piping system, it should be pressure tested for leaks. All piping systems should always include a pressure gauge (digital or dial) for monitoring the fluid pressure. The system should be filled first with water and put under pressure of 1½ times the operating pressure for a minimum of 2 hrs, while the pressure is monitored and the distribution is inspected for leaks. The leak inspection should be completed before installing any piping insulation.
