Water and wastewater systems rely on complex pumping and pipe systems that can wreak havoc in the event of failure.
Since the 1930’s, expansion joints have kept these systems protected from sudden movement related to vibration, pump thrust, earth movement, high or shifting temperatures, and improper anchoring. Originally, these were steel welded and button type joints, but in the 1960’s rubber joints became popular due to their abrasion resistance and flexibility.
Cal Hayes, General Manager, and Stacie Cummings, Waterworks/ProFlex™ Sales Manager for Proco Products, Inc. explain the capabilities and criticality of expansion joints. With over 40 years of experience between them, they share insights on how to prevent devastating failures
