Hey DoDad, how is it that your aerators' tubing do not freeze and crack in the winter? I am on the East Coast of the USA. I'd love to run them all year round, but would the tubing not freeze and crack?
We run aerators all year round (Chicago area - definitely cold here!) and no, the tubes don't freeze. They are the rubber type tubing and are buried about 2 inches underground. But I don't think they would freeze anyway, since they are just running air through them.
