Our comprehensive range of services includes Annual Product Line Testing and Mechanical Leak Detection Testing, both of which are executed with meticulous precision using innovative Estabrook’s line testing and leak detector equipment. With a constant pressure line testing system, Estabrook’s equipment ensures utmost accuracy and allows for testing at lower line pressures. As per regulations, line testing must be conducted at a positive pressure equivalent to 1.5 times the system’s operating pressure, while successfully detecting a leak rate of 0.1 gallon per hour. It is important to note that vacuum tests do not fulfill regulatory requirements for pressurized or suction piping systems.
