The Plumbers & Pipefitters have serviced the construction community since 1889. In November 1904 the Plumbers, Gas and Steam Fitters were given a charter for Stockton California and became Local Union 492. In January of 1920 the Plumbers and Steam Fitters were given a charter for Modesto California and became Local Union 437. In 1997, the Stockton and Modesto local unions merged into the Plumbers, Pipe and Refrigeration Fitters Local Union 442. The new Local covers an eight county jurisdiction in the San Joaquin valley and Sierra foothills.

In June of 2006 Local Union 442 moved into a state of the art administration and training facility, located in North Modesto. The new 25,000 square foot building features a Union Hall Assembly Area and Local 442 Administration Offices.
