Probe Options/Specifications The HYDROLEVEL Story On October 3, 1962, a boiler explosion that claimed the lives of 21 people occurred at a New York Telephone building in Manhattan. This disaster, caused by an undetected low water condition, forever changed the way all steam boilers would be manufactured and installed. Not long after this tragic event, New York Telephone began investigating better ways of protecting their employees and property from such hazards as low water conditions.
