In my hotel, post earthquake, they had to shut the water off for about 24 hours on the top floors of my hotel. Water was turned on the next day.
 

Today I noticed if I pour some tap into a glass, there is a cloudy sediment (?) which clears up in a few seconds. The hotel said to run the water for a time and see if that helps.

 

Just curious if anyone has insight into this? I just shower with the water and use a Brita for tap water for cleaning and steaming vegetables. The rest of the time I use bottled water. 
 

I did read about aeration bubbles, which seem to be the case as the sediment rises and clears.
 

 

Quick update: I have run the water for about an hour, and the cloudiness is gone. So I imagine it was air bubbles that got into the system.
 

Much ado about nothing, I guess. 🙏
