Thank you Sir! I was losing hope that someone would answer. I can't move the diffuser now. So would you continue with my approach of opening the water with the aerator when outside temps are ok? I am in the process of raising the level with the well, so depth numbers will be up by a foot all around by the time the frigid air hits.
Bill,
I think you're fine. Just keep a hole open 24/7 and you will have no worries.
If pigs could fly bacon would be harder to come by and there would be a lot of damaged trees.
