This page covers mid-tier plumbing conferences happening across the U.S. in 2026, with eight events worth knowing if you're planning your trade show calendar before KBIS 2026 pulls attention toward the bigger rooms.
These aren't the massive national shows. They're regional and association-driven events where the room is smaller, the conversations are more direct, and the vendors on the floor are often a better fit for shops at a growth stage. The CertainPath Profit Days Roadshow runs from late January through mid-March across multiple stops, making it useful if you want early-year exposure without committing to one location. The MCAA Industry Forum in Nashville in late April draws mechanical contractors looking at workforce and business issues. If your pipeline includes regional dealers, association buyers, or plumbing contractors outside the big metro markets, these events give you access that the larger shows don't.
