Unrelated water main breaks in Glassell Park and Highland Park left dozens of customers without running water Friday morning.
The breaks came nearly 24 hours after another water main break less than a mile away in Highland Park.
The Los Angeles Fire Department arrived to Monte Vista Street and Avenue 54 around 1 a.m. and discovered an 8-inch water main break that was part of a system built in 1932.
The Los Angeles Department of Water and Power officials say 19 services, mostly businesses, were affected.
A portion of Monte Vista Street was closed near Avenue 54, but it was partially accessible to traffic.
Officials said the break was likely age-related, and it was unrelated to the two water main breaks in Los Angeles on Thursday. Officials said those two occurred on a different system.
A water main had burst on York Boulevard near Avenue 53 around 2 a.m. Thursday. York Boulevard, a major thoroughfare in Highland Park, suffered damage and was closed from Avenue 53 to Avenue 54.
York Boulevard had reopened by Friday morning.
The main break in Glassell Park was restored by noon Friday.
Another water main break was reported in Silverlake Thursday.
Seven water main breaks have occurred in the Los Angeles area this week, four of those in Highland Park alone.
The LADWP said that 23 gallons of water are lost through each leak per day, but that main breaks have decreased over time.
Changes in the weather and pressure on the system could have been causes in the recent main breaks, the LADWP said.
Since 2013, the LADWP has replaced 100,018 feet of pipe.
