PITTSBURGH, Pa. (WPXI) – A boil water advisory was lifted Sunday for hundreds of thousands of people following a massive water main break Friday morning. It flooded a Pittsburgh road, closed schools and had crews with swift water rescue gear pulling people from homes. East Agnew Avenue in the area of Becks Run Road in the city’s Carrick neighborhood was ripped apart by the rushing water. According to Pennsylvania American Water, “acceptable test results” were obtained from the first round of water samples collected. Early Sunday, the second round of ‘clean’ test results were collected. East Agnew Street will be closed for several days, and Becks Run Road was not open for Friday’s evening commute. The approved detour for Becks Run is Carson Street to Glass Run Road to Churchview Avenue to Brownsville Road and back to Becks Run. The water rushed toward homes, filling basements and backyards. Firefighters said the water was 6 feet deep in some yards. Three homes were seriously damaged and there were about 10 homes impacted by the water. The water gushed for about six hours before crews were able to shut it off according to officials.
