National plumbing and mechanical standards continue to evolve, shaping everything from water quality protection to product testing requirements. While these updates originate at the national level, many ultimately influence Florida’s codes, approved materials, and best practices—making it important for plumbers and contractors to stay aware of what’s coming down the pipeline. Current activity from organizations like ASSE, AWWA, ASME, IAPMO, and NSF includes updates to water treatment performance, backflow testing kits, water hammer arresters, and procedures for replacing and flushing lead service lines. New product standards are also emerging for items such as bathroom vanity assemblies with plumbing products and elastomeric test caps.

Additional revisions in mechanical and HVAC-related standards—such as ASHRAE’s clarifications for refrigeration safety, updated fan energy metrics, and new guidelines related to building efficiency—may impact contractors who work on mixed mechanical-plumbing projects. While these proposals are still in various stages of development, they highlight the direction the industry is heading: safer systems, more accurate testing, improved water integrity, and better energy performance. Staying informed now helps Florida plumbers prepare for future code updates and ensures systems continue meeting the highest standards for safety, quality, and compliance. Click here to read more.
