The 6-inch pipe, which was installed in 1925, burst around 5:10 a.m. in the 8300 block of Blackburn Avenue, according to the Los Angeles Department of Water and Power.

“First thing I saw was a big gush of water going down the street then my attention turned it this way and saw jet of water coming out high as the tree old faithful erupting crazy,” resident Shaun O’Sullivan said.

It took LADWP about 45 minutes to shut off the water.
