Homeowners in parts of Vernon, South Windsor, and Ellington woke up to low or no water pressure on Sunday morning due to a water main break.
The break happened on Route 74 near Stop & Shop in Vernon, according to Connecticut Water.
Water has since been restored to most customers. There was still a handful of people without water until about 5 p.m., according to Connecticut Water.
Some customers living near where the break happened may have noticed discolored water because of the issue.
Crews said they flushed out the water system to get rid of any leftover discolored water.
