Foam in water after de-winterizing

For some reason I'm getting foam from the kitchen sink on the cold water, bathroom faucet seems normal. I never put the water filter back in, could that be causing this?

    Dewinterizing yourself just saved you at least $120! Congratulations!
  • The faucet aerators make this "foam" worse. It isn't really foam. It is just air bubbles. If you can unscrew the aerator (careful not to lose any gaskets down the drain) you will likely see that your water is running clear. Another way to see is to run the water into a cup or the palm of your hand and see what it looks like. Foam will remain for awhile - air bubbles will not. If it is air then don't worry about it.
  • Anti-freeze usually causes the water to foam. Run enough through and it will eventually go away.

    If so, you will get the foam (and taste and smell) for a LONG time!
    If you did not, just run your water and it will clear fairly quickly.


    I don't think I did, I winterized according to my manual.

  • You might want to check the screens in the faucet, some times a little rust deposit will do the same foaming especially after a good flush.

  • Run a glass of water, set it on the counter, watch the bubbles dissipate. Air in lines causes this. Not uncommon. Just keep flushing, or ignore and it will go away on it's own.
  • You have air in the lines. As jk stated, just keep flushing it.
