Understanding the Basics of Waterhammer and Surge Suppression

 Date: Tuesday, January 13, 2026 
Time: 1:00 PM - 2:30 PM ET 
PDH Credits: 1.5 

Overview:

Waterhammer is a pressure surge in a piping system due to a sudden change in flow. It can occur when the power to driver is lost, air is expelled from a system, a valve closes too quickly, or a check valve slam shut. This webinar will review what can happen as a result of the waterhammer, some basic physics, and ways to account for it in your pumping system design.

Learning Level – Intermediate:

Intermediate level training is designed for individuals who have some experience and basic knowledge on the topic. It builds upon basic concepts and expands the breadth and depth of understanding supporting the development of skills.

It is recommended that attendees have basic level knowledge or complete basic level training prior to attending this course.

Audience:

Individuals looking gain in depth technical knowledge or those looking for a refresher on applied fundamentals, including experienced maintenance and operation personnel, pump system designers and owners, technical sales, and engineers.

Licensed Professional Engineers:

Continuing professional development is a vital component of the engineering licensure process. Most state licensing boards require continuing professional development as a condition for licensure and renewal of the license to practice engineering. The acceptance of continuing education as it applies to fulfillment of the state licensing requirements for professional designations is at the pleasure of the individual state licensing boards. It is the responsibility of the individual participants to be knowledgeable about their state requirements. Pre-approval of training providers and courses is not required by most state licensing boards, except for the following:

Florida Board of Professional Engineers

Pump Systems Matter is a board-approved continuing education provider for the Florida Board of Professional Engineers: License # CEA361.

New York State Board for Engineering, Land Surveying, and Geology

Pump Systems Matter is approved as a sponsor of continuing education for professional engineers in New York State: NYS Sponsor # 241.
