Troubleshooting milky hot water problem. Milky or cloudy
look from your heater is not harmful and has no health
concerns, but might have an unpleasant look.
The first question before trying to do any repairs is to ask
yourself, why hot water is milky and has the cloudy appearance?
The main cause of the cloudy appearance is the
presence of the additional air (dissolved oxygen and
other gases) in the plumbing system. There are several reasons how the
extra air got in the plumbing, through the heater and the
- The utility companies
occasionally switch from one well source to another, which results in
developing an excessive air in the system. These companies can also
increase the pressure in the distribution line through the pumping
station so the additional air will enter the plumbing system. Cloudy or
milky hot water, due to the reasons from the above is something that
you cannot change but the utility company should be consulted if the
problem persist for longer period of time.
- The aerator that is installed
in the faucet is something that might also create milky and cloudy
appearance in your hot water, as it generates more air.
- If your home plumbing system and the heater use
system, the pressure from the ground can cause the air
bubbles being entrapped inside the water pipeline. Water under pressure
contains more dissolved air than at the atmospheric pressure.
When water enters the heater's tank the air is dissolved and by opening
the tap millions of small bubbles are released.
- The air might expand when the underground temperature
- Milky water appearance often occurs when the
utility company service the major pipelines.
- If the incoming water to the heater is clear, but
milky or cloudy when the tap is open, the answer is in a
heating process and pressure inside the tank so the gases dissolved in
the water will begin to escape and separate.
As you can see milky look is actually not a
problem. Troubleshooting is simple... it takes time
to clear up, and the unpleasant milky look inside your glass of water
Keep in mind that cloudy or milky hot water is
not harmful for you, it represents the air bubbles and
once they rise to the surface they disappear so as the
milky hot water appearance. Also, this problem is not related to the
hot water line only, cloudiness can be found in cold water line also,
where it dissolves faster than in the hot. It can be
visible in new and old heaters equally.
