Customers in Grifton are adviser to boil any water used for eating or drinking after a water main break on Church and Charles Streets caused low water pressure.
Officials said people should bring water to a rolling boil for one minute, and let the water cool before using it.
Bottled water is also a safe alternative.
The notice will be lifted after the water is tested to ensure that no contamination occurred during the low-pressure period. That’s expected to happen sometime on Thursday.
