I’m citing several tank water heater installs this week where the 3/4-inch TPR discharge is reduced, trapped, or just pointed onto the garage floor; under 2021 IPC 504.6 it must be full-size, gravity, untrapped, and terminate at an approved location. How are you documenting corrections when builders claim “local practice” — section reference on the red tag with a reinspection photo, or do you also request a manufacturer bulletin?
