If that were the case Trump wouldn’t have even been on the ballot.

Lady, the question was “do thongs touch you butthole?”

Please tell whoever is holding the keys that a random on the internet said to let you cum, if not for your own sake then for the rest of ours.

You see it on the left as anti-imperialism. Obviously not the same thing as the “America first” crowd, but the general sentiment that the US should not be as directly involved in the affairs of other countries has been on the rise for a long time and poll numbers bear that out

They’re pretty standard parts so don’t feel like you need to go with Fantech in particular, feel a little like I accidentally shilled for them a bit, just happened to be on their website (AFAIK they do make good stuff though). Glad that it helped and best of luck :)

The switch would be something like this. I think differential pressure between the inside of the duct and your kitchen would work.

and any “normally closed” damper would work. Wired up such that when your range hood is switched on, it also switches the motor in the damper on so that it opens.

The simplest thing would be a pressure or airflow sensor hard-wired to the switch for the hood itself.

Also consider instead of a 1 way valve installing a damper that only opens when your range good is turned on.
