Steps to Take After A Water Main Shut-Off:
Flush Your Pipes – After the water main is repaired, open all fixtures and allow water to run until clear.
Start by opening the cold water faucets and allow them to run for at least 2 minutes after they run clear.
Then run the hot water until it’s hot. Wait an hour or two and then run the hot water again. This ensures that your hot water tank is flushed.
After experiencing a water main break or repair, the water system is flushed by the water department.
In most cases, you will not notice any difference in your water, but there is a chance you may have air in the line or notice a reddish or murky color. Flushing your system after the water has been restored is a good practice and should take care of those problems.
