Water is one of our most precious resources, yet we waste billions of gallons every year—often without even realizing it. But what if the biggest solution wasn’t flashy new technology, but something as simple as the toilet, showerhead, or faucet in your home?

In this episode of The Authority Podcast: Plumbing Mechanical, host Christoph Lohr welcomes back Kerry Stackpole, CEO & Executive Director of Plumbing Manufacturers International (PMI), for a powerful conversation about how everyday plumbing fixtures are already making a massive impact in the fight for water conservation. Thanks to the U.S. EPA’s WaterSense program, these unsung heroes have saved an astonishing 8.7 trillion gallons of water—enough to sustain millions of families. But there’s still so much more to do.

With only 22% of California’s toilets meeting WaterSense standards, we’re leaving an enormous amount of savings untapped. Christoph and Kerry explore how small changes—like upgrading outdated plumbing fixtures—can lead to huge environmental and financial benefits. They also dive into the policy shifts, technological advancements, and industry leadership driving a future where wasted water becomes a thing of the past.

This isn’t just about efficiency—it’s about preserving our water for future generations. Tune in to hear how you can be part of the solution and why the plumbing industry is stepping up to protect our most vital resource before it’s too late.

In this episode, host Christoph Lohr speaks with Kurt Steenhoek, International Representative of the United Association of Journeymen and Apprentices of the Plumbing and Pipe Fitting Industry, to discuss a critical issue—water quality.

💧 How do we ensure safe drinking water in hospitals, nursing homes, and public buildings?
💧 What lessons can we learn from the Flint water crisis and the rise of Legionella outbreaks?
💧 Why are certified plumbing professionals essential in protecting public health?

Kurt unpacks the ASSE 12060 series certifications, the industry’s gold standard for ensuring clean, safe water in critical facilities. Learn why training, certification, and proper implementation are key to safeguarding our water supply.

What if a simple shift in plumbing design could save thousands of dollars, deliver hot water faster, and make homes more affordable—all while conserving precious resources? In this must-listen episode, host Christoph Lohr sits down with industry trailblazers Robert Campbell Sr. and Amanda Johnson from Villara Corp. to reveal how they’re revolutionizing homebuilding with the IAPMO Water Demand Calculator.

Villara Corp. has helped builders save up to $5,000 per home, reduce construction waste, and optimize plumbing systems for over 5,000 homes. Their insights could transform the way we think about efficiency, affordability, and sustainability in housing.

In this episode, we discuss the General Services Administration (GSA) order to address the risk of Legionella and other waterborne pathogens in the water systems of GSA-controlled buildings. The GSA, which owns 1,600 federal buildings and leases space in over 6,500 buildings nationwide, was spurred to action after detecting elevated levels of Legionella bacteria at six GSA-controlled buildings in different regions since 2023. Our guest Dr. Abraham Cullom, a microbiologist with expertise in plumbing systems, talks about the GSA order and the urgent need to stay on top of emerging best water quality practices for plumbing systems to protect building occupants.

Join IAPMO experts Dan Cole and Christoph Lohr for a technical exploration of storm drainage system design and the critical equations engineers need to calculate effect flow rates through piping.

Among the key insights is the impact of pipe material on flow velocity. For instance, PVC and cast iron pipes of the same size can have vastly different flow capacities. Dan and Christoph discuss the key differences between the Manning and Darcy-Weisbach equations, why current plumbing code tables may not tell the whole story, and how proposed code changes could give designers more accurate tools for material selection.

In an era where storms are increasing causing urban flooding from excessive rainfall events, this episode will help engineers to make informed decisions for accurate storm drainage system sizing and ensure optimal performance and longevity.

In this episode, we discuss challenges and opportunities in residential water use and efficiency. Our expert guest, Andrew D. Morris, Senior Manager of Policy & Programs with the Alliance For Water Efficiency, shares how water consumption in single-family and multi-family homes has evolved over the years, including a 15% decrease in indoor water use between 1999 and 2016 driven by state-level fixture standards and federal appliance regulations. Andrew provides a vision for future areas of improvement, including right-sizing premise plumbing and water heater systems, meter sizing and sewer capacity certifications, and utility-side adjustments to connection-related fees and policies.

In this episode, Jonah Schein, Technical Coordinator for Homes and Buildings with the U.S. Environmental Protection Agency (EPA) WaterSense® program, demonstrates how water-efficiency measures also save energy and reduce carbon emissions, using data from 219 WaterSense-labeled homes in Menifee, California.  

Jonah describes how every gallon of water has an "energy signature" based on the processes required to extract, convey, treat, and distribute that water, noting the dramatic differences among various water sources, with some requiring over 20 times more energy than others. Noting the benefits of right-sizing plumbing pipes for water-efficient fixtures, Jonah emphasizes the tremendous opportunity in leveraging water efficiency to cost-effectively reduce energy use and carbon emissions.
