Japanese Construction Quality: The Marble Inspection Test

Kristian Geiger on Instagram: "🚨 This is a change-of-direction problem. Under IRC G2419.4 and IFGC 408.4, sediment traps must be installed so debris can fall out of the gas stream before it reaches the appliance. That only happens when gas flow is forced to change direction, allowing gravity to do its job. Here, gas travels straight through the tee into the control valve, meaning sediment can stay suspended instead of dropping into the trap. 🔄 No directional change = reduced effectiveness Code
