There are too many bad jokes to be made about blower doors…I couldn’t resist.

As soon as we turned the fan on we started smelling sewer gas (plumbing is just at rough, so no traps installed. So we plugged them with rags and fiberglass (not exactly airtight, but kept the stink down and gave us a more accurate reading. Andy didn’t have a “C ring” to be able to get below 300cfm, so Brandon got one from his truck…

I’ll say it again: this is a great team!
