PITTSBURGH, Pa. (KDKA) – More than 24 hours after a massive water main break in Carrick, crews are still on the scene.

While the water main break is no longer gushing water down East Agnew Avenue, crews are continuing to work around the clock.

KDKA’s Chris Hoffman reports about 30 houses in the immediate area of the break had no water service as of this morning, but it has since been restored.

Bridgeville Fire Department has put an 8,000-gallon water buffalo in place for residents at 370 Commercial Street in Bridgeville. Those in need of water only need to bring a container to carry the water.

The break happened around 5 a.m. Friday morning in the 400 block of East Agnew Avenue when a 24-inch water main broke. The water flowed until it was shut off around 11:30 a.m.

The Red Cross said three homes were directly impacted by the break. All three homes were evacuated.

According to Pittsburgh Public Safety, two people and several pets had to be rescued.

Penn American said they had to find the valve that was under the rushing water, which was why it took so long to shut the water off.

There was so much water lost, the South Hills and southern Allegheny County communities lost pressure for most of the day.

About 35 communities are under a boil water advisory that’s expected to last until at least Sunday.
