    Can Anyone tell me why and or How air can be infused in the water coming from my 40 gal. elec. hot water heater?

    Seemed to start all of a sudden but that could be false cause who watches a hot water stream all the time?

    Hello: Two things come to mind. If air is getting pulled in at the source either by your water utility or at your well, the water heater is a place for it to accumulate. Air is absorbed into water under pressure. As soon as the pressure is off, (that would be as it comes out the tap) the air comes out of solution. Hence the milky look. An overactive anode rod could do the same thing, putting oxygen and hydrogen into the water of the tank, particularly if it isn’t used much. This usually shows up as spurting at the faucet used first thing in the morning.

    If you are on a municipal system and your neighbors have the same “milkiness”, you could call the utility and ask them about it. It is not a health concern and it is more common at the end of summer when pumps are working hardest. Hope that helps.

    Yours, Larry
