Question:
I noticed that within the past month or so I have a lot of air when I
turn on the hot water. *As the water gets warmer the air gets worse..
Since it's only the hot water I assume it's a problem in my house, but
just to be sure I checked with my neighbors and the do not have any
problems. *We have town water.
What could be causing this? *The air comes out in strong bursts
sometimes and it makes the pipes vibrate.
thanks.

Hello Jane,


Steam bubbles wouldn't reach your faucet unless your tap water was
boiling hot.


Water tanks have anodes to keep them from rusting. *Anodes produce
bubbles of hydrogen and oxygen. *It happens faster with soft water.
Some anodes are designed to slow the bubbling.


I'll bet you aren't using as much hot water lately. *That gives the gas
more time to accumulate.


I use very little hot water lately. *You could be right. *Anyway, the
plumber is coming next week.


Thanks for the response.

Maybe it's related to a strange experience I had a couple of years ago.
* Does your hot water look milky?

My hot water supplies four sinks, a washer, and a shower. *One day when
I drew some hot water in a glass at the sink in the main bathroom, tiny
gas bubbles made it look white. *The water slowly cleared as it sat in
the glass. *I tried it again. *Still white. *I removed the aerator.
Still white. *After I drew more than a quart, it still wasn't clear. *It
was clear the next day and ever since.

I wonder if the white appearance came from tiny bubbles of hydrogen and
oxygen that had been dissolved in the water until I reduced pressure by
opening the tap. *I don't know why the water with the dissolved gases
would have collected in the pipe to that tap.

If more gas had accumulated in the water, perhaps it would have
sputtered from the tap. *I wonder why the water was cloudy that day but
not before or since. *Could something unusual in the town water that day
have increased gassing in my water heater anode?


YES! I have noticed in the last couple of weeks that the hot water
is cloudy. Exactly as you described yours. Did you have air in the
pipes at that time?
