Yup, familiar with the regular reasons for milky looking water.


More than likely the water in the pipes was cold and had dissolved air in
it. The hose was warm, and the air came out of solution because of the
decrease in pressure and the increase in temperature. When the hose
cooled
to the same temperature as the water, the dissolved air coming out of
solution due to just the drop in pressure wasn't enough to make it cloudy.

Also, if it was a rubber hose it may have had a thin coating of talcum
powder or cornstarch inside leftover from manufacturing.

Yup, familiar with the regular reasons for milky looking water. I have since
learned that lead is added to the plastic in hoses to keep them flexible.
This shouldn't be a problem for the plants, but it makes you wonder about
the use of recylced plastics in manufacturing.
