The Plastics Pipe Institute, Inc. (PPI) announced today that its Building & Construction Division (BCD) has elected Bill Melvin of Legend Valve (Auburn Hills, MI) as Division Chair and Jim Paschal of Aquatherm (Lindon, UT) as Vice Chair. Melvin, who will also represent the division on the PPI Board of Directors for the next two years, takes over from Joseph Poniatowski of Asahi/America. The changes took effect June 1, 2024. PPI’s BCD focuses on pressure piping materials for plumbing and mechanical applications.
Bill Melvin has served on the Management Committee in several roles, including the Communications Committee Chair and Vice Chair. Jim Paschal also serves as Chair of PPI’s Polypropylene Pressure Pipe Steering Committee and formerly served as R&D Projects Chair. That position will now be filled by Rick Stock of Uponor. Brian Conner of Charlotte Pipe and Foundry joins the committee as Codes & Governments Affairs Committee Liaison.
Adam Grier of iNOEX serves as the Communications Committee Chair, and also as Chair of the PPI Umbrella Marketing Committee. Jason McKinnon of Viega LLC serves as the PPI Education Committee Chair and also as the BCD Education Chair, a position he has held for more than eight years. Forest Hampton III of Lubrizol continues as Advisory Council Liaison & Strategic Planning Chair.
According to Lance MacNevin, P. Eng., director of engineering for PPI’s Building & Construction Division, “PPI’s management committee members provide significant guidance to staff on topics from research, codes and standards to education and advocacy. These new leadership positions solidify their continued commitments to PPI and the piping industry. We are grateful for the volunteer service of these dedicated members.”
PPI is the major North American trade association representing the plastic pipe industry. The Building & Construction Division represents plastic pressure piping materials such as CPVC, HDPE, PEX, PE-RT, PP-R, and PP-RCT.

The Plastics Pipe Institute, Inc. (PPI), has published a new recommendation related to the direct connection of plastic piping materials CPVC, PE-RT, PEX, and PP to tankless water heaters.
Available on PPI’s website, PPI Recommendation H Direct Connection of Plastic Piping Materials to Tankless Water Heaters for Domestic (i.e. residential) Applications provides clear guidance on the question of direct connection of these piping materials to tankless water heaters. PPI is the major trade association representing the plastic pipe industry.
“PPI Recommendation H answers questions which plumbers and builders have been asking about whether it is appropriate for plastic pressure pipe materials to connect directly to the cold-water inlet and hot-water outlet of domestic tankless water heaters, without the use of metallic flex connectors. Based on our research, these direct connections are usually acceptable,” explained Lance MacNevin, P. Eng., director of engineering for PPI’s Building & Construction Division.
“To help answer this question, PPI and our members researched Canadian and US model plumbing codes,” he continued, “reviewed the published literature on dozens of tankless water heaters, and confirmed the recommendations of plastic piping system manufacturers. Based on the proven high-temperature capabilities of these piping materials and the relatively consistent water temperature control of modern tankless water heaters, there is no technical reason to prohibit direct connections. Of course, installers must follow local code requirements and the manufacturer installation instructions.”
“As stated in Recommendation H: Piping systems using the materials CPVC, PE-RT, PEX, and PP, which carry a pressure rating of 100 psi at 180°F (690 kPa @ 82°C), and which are intended and certified for hot and cold potable water distribution systems according to industry standards and relevant codes, may be connected directly to tankless water heaters which are intended for domestic (i.e. residential) applications, unless prohibited by local plumbing code or the specific water heater manufacturer.”
According to PPI President David Fink, “The research on this topic was prompted by an inquiry from a major builders group. The rapid development of Recommendation H demonstrates the ability of PPI members to collaborate and respond quickly to industry questions about responsible usage of plastic piping materials.”
Published on PPI’s website directly at recommendation-h-direct-connection-tankless, Recommendation H is one of several PPI documents related to the design and installation of pressure pipe materials for plumbing and mechanical applications, which are all published as a service to the industry.
