Ended up drawing a little diagram with notes right on the wall (in pencil, thankfully) just to show him what was going on.
Been there. Last year I had to walk an inspector through a fresh air intake setup that was actually *better* than code, but because it didn’t match the exact diagram in the book, he flagged it. I ended up pulling out my phone and showing him airflow readings just to prove the point. Sometimes it feels like they want you to follow the letter, not the spirit, of the rules.
Honestly, I get where you’re coming from, but I kind of see it from the inspector’s side too. They’re not always trained to evaluate “better than code”—they’re just making sure things are safe and consistent. I’ve had to redo perfectly good ERV setups just because they didn’t match the book diagram, and yeah, it’s frustrating. But if every install was “custom,” inspections would be chaos. Still, I wish there was more room for common sense in these checks...
Struggling With Ventilation Inspection Requirements Lately
That’s been my experience too—had to rip out a setup that worked perfectly fine just because it didn’t match the exact diagram. I get why the rules are there, but sometimes it feels like common sense gets left at the door. Hang in there, you’re definitely not alone with this.
Yeah, it’s wild how strict they get about matching those diagrams. I had a vent run that was actually quieter and more efficient than the “approved” way, but nope—had to redo it. Sometimes I wonder if inspectors have ever actually installed this stuff themselves...
Totally get where you’re coming from. It’s frustrating when you know your way actually works better, but the rules are the rules. I’ve had inspectors nitpick stuff that made zero difference in real life—sometimes it feels like they’re just following a checklist, not thinking about the actual function. Hang in there, though. Once it’s done, you won’t have to deal with it again for a long time.
