The City of Rockville has fixed a 24-inch water main that burst in Potomac this week.
The line was being flushed Friday and officials were testing the water for safety.
Mandatory water restrictions imposed after the pipe burst will remain in effect until at least noon Saturday, officials said. Residents are asked to use water sparingly and avoid washing cars, watering lawns and topping off swimming pools. City officials also asked that residents limit toilet flushes and only run dishwashers and laundry machines with full loads.
The water main burst at 3:30 p.m. Wednesday, spewing asphalt and creating a spectacular geyser. Rockville is receiving water temporarily from the Washington Suburban Sanitary Commission.
