Welcome Attendees

Over the last 45 years generations of contractors, technicians, supervisors, engineers, municipal officials, students and more have made the Flow Expo an annual event.

We are proud to have served multiple generations of contracting families in their desire to Experience, Explore and Expand their knowledge of the PHC trades. We welcome today’s and tomorrow’s professionals to experience all the show’s 170,000 SF has to offer. We encourage attendees to engage the exhibitors, to learn more about what the PHC industry has to offer and to take time to attend the education sessions throughout the day.

The Flow Expo is the trade show for the PHC Industry, by those in the PHC Industry…  PHCC Los Angeles.
