LOS ANGELES - Water service has been restored for more than 9,200 residents in Granada Hills and Porter Ranch after days of a major outage caused by a broken valve. 

What we know:

Los Angeles Department of Water and Power (LADWP) crews fully restored water service at 2:27 a.m. on Monday. 

Residents can now use tap water to take showers, flush toilets, conduct water landscaping and any other household or business needs.

The 10-million-gallon Susana Tank is being refilled through the LADWP's normal pumping process.

The backstory:

The outage began last Tuesday when a valve broke during repair work at a pump station, cutting off the flow through a 54-inch pipeline that feeds the Susana Tank. Crews had to excavate 24 feet underground to access the damaged valve.

The site's complexity, located near oil pipelines, a fiber-optic line, and a gas line, required the trench to be widened before the valve could be removed.

The outage came during a mini heat wave that saw temperatures soar well into the 90s in the affected area, which was bounded roughly by Rinaldi Avenue on the south, Balboa Boulevard on the east, De Soto Avenue on the west and the foothills and hills to the north.

What you can do:

While water service has been restored, customers are still urged to continue using boiled or bottled water until LADWP staff completes two 18-hour rounds of water quality testing. 

The LADWP has distributed more than 1 million bottles of water and delivered over 1,200 gallons to vulnerable homebound residents.
