  • Dissolved Oxygen in Hot Water

    Please refresh my memory. What is the cause of dissolved/diffused oxygen in the hot water. Water looks milky but it's just air bubbles. Is it the aerator or something to do with the water heater. I'm just remembering back as someone has asked me about it recently.

    Assuming the dissolved oxygen is not related to the water source or distribution system it could be a fixture aerator.

        Ok. This link pretty much explains it all. http://fwid.org/images/Why_is_My_Water_Cloudy2.pdf
        Basically, Cold water and water under pressure hold more dissolved air. Our water is especially cold here in the winter. Heated water and/or the release of pressure will cause the air to separate from the water. The air is released partially released in the water heater as it heats up but it is still under pressure. The air gets full emancipation as it exits the faucet spout.
        Presto Chango!
