For the past 72 years, the E.J. Zimmer Technical Seminar has proved to be an educational, progressive endeavor.

This year’s Technical Seminar, held Monday, Sept. 23, will feature three presentations on the topics of geothermal heating and cooling, backflow prevention, and Legionnaires’ disease. Earn CEUs and learn something new!

Since 1947, the E.J. Zimmer Technical Seminar has enabled attendees to explore and learn about various segments of the plumbing, mechanical, and water quality industries. Those who attend have the opportunity to learn and gain perspective directly from respected and experienced experts. Presentations range from in-depth case studies, to technical explanations of new technologies, to updates on codes, standards, and legislation. While presentations range in format, time and subject, what remains consistent is the fact that everybody leaves the seminar having learned something new.

Admittance to the E.J. Zimmer Technical Seminar is included with all registration categories for the 2019 ASSE International Annual Meeting. Registered attendees are also welcome to attend the IAPMO Education Sessions on Wednesday, Sept. 25 and Thursday, Sept. 26.

Inspecting Geothermal Heating and Cooling Systems
Presented by Cary Smith

Geothermal Heating & Cooling Systems are increasing in popularity around the nation. This highly efficient technology draws on the constant temperature of the earth to heat and cool buildings. Inspectors need to be aware about how the systems function, the various types of installations, and the do’s and don’ts of what they see in the field. This presentation will discuss the different aspects of geothermal projects that concern the inspector, including borehole drilling, piping installation, code compliance, and best practices for installing contractors. Attend this presentation and know what you see when you walk onto a geothermal project site.

Backflow Prevention for Chemical Dispensers and Kitchen Equipment
Presented by Sean Cleary and Ron Lord

Perhaps one of the most misunderstood products in the plumbing industry is the chemical dispenser. What is the proper cross-connection needed to protect the water supply? Is the protection already part of the dispenser or should it be installed on the water supply upstream of the dispenser? Do dispensers require a dedicated water supply or can they be supplied by another fixture, such as a service sink faucet? Do they require a permit or a licensed plumber to be installed? The answers to these and other questions will be discussed and debated at this seminar. We will examine the code requirements, innovated products related these installations, along with training programs and policies that exist in the industry for inspectors, consumers, and contractors working to ensure that this equipment is installed and used properly.

Ending Legionnaires’ Disease: An Achievable or Audacious Goal?
Presented by Janet Stout, PhD

Ending Legionnaires’ disease requires more than controlling Legionella in building water systems. Some agencies are now focusing on reducing and maintaining Legionella to zero. However, this is an unrealistic proposition due to the nature of the bacteria and the complexity of building water systems. If you find Legionella in you water system, don’t panic. Avoiding outbreaks requires a team approach, knowledge of Legionella, and a proactive plan so you know how to respond not react when you find Legionella in your water. Topics included are: Understanding Legionella in the Built Environment, Overview of Legionnaires’ disease, ASHRAE 188: Risk Management Approach and Its Limitations, Legislation: Necessary Complement to ASHRAE 188, and Strategies for Prevention.

Liability and Risk Management of Legionella in All Piped Systems
Presented by Kurt Steenhoek and Richard Benkowski

Does your firm participate in new construction, renovation, and maintenance of healthcare facilities? Does your firm work on cooling towers, ice machines, or humidifiers in hospitals, skilled nursing homes, or critical access hospitals? Install or renovate plumbing, medical gas piping, or fire protection systems? If you answered yes to any of these questions, you should not pass up this opportunity to help your customers and workers be in compliance with the CMS and CDC for all mechanical systems. Every healthcare facility in mandated to create a water management team compliant with ASHRAE 188-2018. Every water management team requires involvement by mechanical contractors. Are you ready to be a designated representative to help the water management team make informed decisions about cooling tower maintenance? Patient centered ice machine upkeep? All participants will learn legionella intervention and how to map, monitor, identify risk, offer remediation, and provide liability limiting documentation as required by ASHRAE 188-2018.

2018 UPC Drainage System Design Challenge
Presented by Steve Hart

Think you know the UPC? How well do you know drainage systems? This interactive, hands-on session will put your knowledge to the test. Attendees will be divided into teams and each team will be given a scenario. Each team will then be tasked with assembling a drainage utilizing model plumbing system components that will is both code-compliant and fulfills the challenge in their scenario. Once completed, teams will share their constructed systems with the rest of the class and discuss the prominent code issues related to their scenario. This is a great opportunity to be a part of a training experience that is highly engaging, entertaining, unlike any other training you have had before.

2018 UMC Refrigeration Systems, Walk-In Coolers, Machinery Rooms, and Mechanical Chillers
Presented by Tim Collings

Chapter 11 of the UMC has undergone a lot of changes, most of which focus on the refrigeration machinery room. This session will focus first on the new format and requirements for machinery rooms and then on the code changes. The discussion will also focus on safety devices and relief device discharge locations as well as ventilation installation, testing and refrigeration classification.

2018 UPC Interceptor Sizing and Installation
Presented by Bruce Pfeiffer

This session provides an in-depth discussion of the history, evolution, and current installation and sizing of grease traps and interceptors. The discussion includes the history of grease traps and interceptors from their earliest installations in the late 1800s through current times. Also discussed the inclusion of grease traps and interceptors in the first Uniform Plumbing Code and the evolution of sizing and installation requirements from the 1946 UPC through 2018 edition. At the conclusion of the presentation, participants will have an opportunity to apply their skills by sizing waste systems that contain both hydro-mechanical and gravity grease interceptors.

UPC/UMC Workshops
Presented by UPC/UMC Workshop Committees

The UMC & UPC Workshop Committees present an opportunity for participants to test their code knowledge and learn from their peers. During the workshops, participants are placed into groups and are given drawings of installations and asked to determine if the systems and components are in compliance with the applicable 2015 Uniform Code. The findings are then presented to everyone in attendance to determine if they are correct and discuss any code issues discovered in the drawings.

2018 UPC/UMC Taking a Critical Look at Real World Installation
Presented by Laura Ceja

Understanding of code theory still requires a practical working knowledge of field application that can be applied while conducting inspections. In this interactive seminar, participants will practice mastery of code by recognizing violations in various plumbing and mechanical field installations. Real life scenarios are presented and discussed, while best practices will be explored in detail.
