The Plumbing-Heating-Cooling Contractors–National Association (PHCC) welcomed PHCC members, chapter executives, and corporate partners to Washington, D.C., May 16-17, to meet with lawmakers and educate them on energy, economic, and workforce policies that are important to the industry and consumers.
Before heading to Capitol Hill as industry experts, members first heard from political expert Charlie Cook, who was the keynote speaker for the event. Cook spoke on the current political landscape, lessons from the 2022 midterms, and predictions for 2024.
After hearing from Cook, the group was briefed by PHCC Legislative Affairs Director Mark Valentini, PHCC Vice President of Regulatory Affairs Chuck White, and a panel of other industry lobbyists. Panelists included Jim Collura, vice president and director of government affairs for the National Energy & Fuels Institute (NEFI); Steve Rossi, vice president of advocacy for the American Supply Association (ASA); and Robert Wolfer, manager of government relations for Bradford White Corp (PHCC Strategic Partner). That evening, the group attended a reception in the historic Caucus Room of the Cannon House Office Building. This reception was held in conjunction with the Heating Air-conditioning and Refrigeration Distributors International (HARDI) and the Air-conditioning, Heating and Refrigeration Institute (AHRI). Members of Congress stopped by to network with members of PHCC and these other industry groups.
The next morning during breakfast, attendees heard insights from a second Washington Insider panel consisting of Craig Brightup, chief executive officer of the Brightup Group LLC; Matt Kiessling, senior director of state affairs for the American Gas Association (AGA); and Christopher Lindsay, vice president of government relations for the International Association of Plumbing and Mechanical Officials (IAPMO – PHCC Supporting Sponsor). After a quick stop for a picture on the Capitol steps, they headed to their respective meetings. In total, 71 PHCC members from 27 different states had 111 meetings with elected officials and their staffs. At a closing roof-top reception that evening, members spoke in-depth about how much they valued the in-person meetings on Capitol Hill, in addition to getting to participate in the rest of the sessions as a part of this two-day event.
“The 2023 PHCC Legislative Conference was an extremely valuable event for all who attended,” said PHCC—National Association President Dave Frame. “Besides the very beneficial one-on-one meetings with legislators, the conference was a great opportunity for PHCC members to connect with each other and with others in the industry supply chain. Together, we are able to accomplish so much more on behalf of our members, the industry, and society.”
The conference was sponsored by PHCC Corporate Partner Federated Insurance. Next year’s event will be May 21-22, 2024.

The International Association of Plumbing and Mechanical Officials (IAPMO) has been selected to serve as the ANSI-Accredited Standards Developer (ASD) to pursue the national adoption of ISO 30500, Non-sewered sanitation systems — Prefabricated integrated treatment units — General safety and performance requirements for design and testing.
ISO 30500 is an international standard developed by 32 participating economies and 16 observing members where ANSI served as the U.S. Technical Advisory Group (TAG) Administrator for ISO PC 305. The U.S. TAG recently voted to pursue the national adoption of ISO 30500 and selected IAPMO as the ASD to pursue this effort. ISO 30500 was published in early October 2018.“IAPMO is delighted to have been selected to serve as the ASD to pursue the national adoption of ISO 30500,” said IAPMO Group CEO GP Russ Chaney. “IAPMO will facilitate the development of this important standard working in support of the U.S. TAG and will ensure that all materially affected interests have the opportunity to have their contribution considered. We look forward to beginning this very important effort in the coming weeks.”
The ISO 30500 standard specifies general safety and performance requirements for design and testing, as well as sustainability considerations, for non-sewered sanitation systems (NSSS). An NSSS, for the purposes of this document, is a prefabricated integrated treatment unit comprising frontend (toilet facility) and backend (treatment facility) components. It is applicable to sanitation systems that are either manufactured as one package or manufactured as a set of prefabricated elements designed to be assembled in one location without further fabrication or modification that influences the system function.
IAPMO will be generating a technical committee to be responsible for the adoption of the national standard. The technical committee will operate in accordance with ANSI Essential Requirements: Due process requirements for American National Standards and the IAPMO PP-1, Policies and Procedures for Consensus Development of American National Standards. A notice seeking participation for this committee will be published soon.
“It is a testament to the confidence the industry has in IAPMO, which in turn strives to continue to serve the industry to protect the welfare of public,” said Hugo Aguilar, IAPMO vice president of Codes and Standards.
For more than 30 years, IAPMO has developed plumbing product standards as American National Standards, initially as the Secretariat for the ANSI Z124 Technical Committee in 1984, and since 2005 independently under its own American National Standards Institute (ANSI) accredited standards development procedures. IAPMO is also accredited by the Standards Council of Canada (SCC) for the development of National Standards of Canada (NSC), thus holding responsibility for the development of CAN/IAPMO designated standards.
Founded in 1926, IAPMO is a worldwide leader in the promotion of healthy and safe plumbing and mechanical systems. IAPMO has developed industry standards for more than 30 years, with a focus on plumbing products, water efficiency, solar heating systems and components, mechanical products (including heating, ventilation, cooling and refrigeration system products), and products used in the recreational vehicle and manufactured housing industry.
