The Flow Expo began in 1975 as the PHCC Products Show, presented by the PHCC of the Greater Los Angeles Area and housed in the basement of the associations headquarters. The exhibitors were on table tops and the attendees were treated to a giant sub sandwich for lunch.

The show proved to be a success, filling the need of exhibitors to demonstrate their products and services and that of trades professionals to stay aware of what was new in the PHC industry.

Over the next ten years the show steadily grew...

In the 1980's and 90's the show continued to grow and that meant finding a new home. The newly name PHCC Southern California Plumbing, Heating, Cooling Industry Trade Show found new venues including the Los Angeles Convention Center, Pasadena Convention Center and the Pomona Fair Grounds.

WIth each move the show became bigger and better, drawing exhibitors and attendees from areas outside of Los Angeles. The show had truly become THE Southern California show.

The new Millennium brought a new home, the Long Beach Convention Center. Located in the picturesque city of Long Beach, the now titled "Flow Expo" shares the spotlight with the Aquarium of the Pacific, the RMS Queen Mary and Shoreline Village.

As the largest annual trade show of its kind in the United States, the Flow Expo continues to serve the PHC industry by bringing together exhibitors from across the U.S. and Canada to exhibit over 400 brands from across the world. Exhibitors aren't the only ones that have found the trip to Long Beach to be beneficial, attendees are from though out the U.S. with a large portion representing the western region from Canada to Mexico.
