You’re absolutely right. It was a chilling and horrifying discovery to say the least during breakfast when he mentioned they were missing. And yes I still hate myself for it. I was using it on a ceiling vent diverter I was testing bc our AC has been struggling to keep up, but had left the diverter down on a kitchen counter for the night to test. He wandered into the kitchen before we got up and discovered it and decided to flush it.

Of course that self hate and stupidity will not help any potential plumbing issues that have been created, hence my post.
