City of LA Announces Boil Water Notice Lifted in Granada Hills and Porter Ranch

In coordination with City Departments, LADWP distributed the equivalent to 2.5 million bottles and over 7,000 gallons to customers

LOS ANGELES - The City of Los Angeles today announced that LADWP has lifted the Boil Water Notice in Granada Hills and Porter Ranch following rigorous testing and reporting of water quality results to the California Division of Drinking Water. The tap water is safe to drink. Impacted customers may now resume regular use of tap water but LADWP strongly recommends that customers flush their pipes by turning on all of the faucets one by one to let the old water flush out over the course of roughly five minutes. Customers impacted by the Boil Water Notice will receive a $20 bill credit for water flushing. Visit ladwpnews.comfor more information.

Flushing guidance:

• Remove aerators and screens from all faucets. Set water-softening devices and filters, both point-of-use and whole-house, to "bypass mode."

  • Flush outside plumbing: open and flush external hose bibs/faucets for about 5 minutes or until water is clear and temperature is constant.

  • Flush cold water: run all cold water faucets on the property beginning with the faucet closest to the water line. Run the water at the highest flow (or fully open) for 5 minutes or until water is clear and temperature is constant. Then turn off all faucets in reverse order.

  • Flush hot water: drain your hot water tank to discharge any accumulated sediments. Wait for the hot water tank to refill then run all hot water faucets on the property beginning with the faucet closest to the water line. Let all faucets run at the highest flow (or fully open) for 5 minutes. Then turn off all faucets in reverse order.

  • Flush all toilets: a one-time flush should suffice.

  • Automatic Ice Makers: dump existing ice and flush the water feed lines by making and discarding three batches of ice cubes. Wipe down the ice bin with a disinfectant.

  • Clean and disinfect aerators and screens: prepare a 20% liquid chlorine bleach solution by adding 1 cup of laundry bleach to 4 cups of water. Place aerators in solution for no more than 5 minutes (any longer may cause damage to aerator) then briefly rinse with clean water and reattach to faucets, shower heads, and fixtures.

  • Flush appliances: run empty dishwasher and washing machine once on rinse cycle. Flush water dispenser on refrigerator for 5 minutes.

  • Replace all filters and reset all water devices from "bypass mode." This applies especially to carbon filters and others that are near the end of their life.

  • Reverse Osmosis (RO) units: Replace pre-filters, refer to owner's manual for specific guidance.

  • Water softeners: Run through a regeneration cycle.

With the lifting of the Boil Water Notice, all bottled water and recycled water distribution centers will be closed.

Customers who may have further questions about water quality in their area can visit the water quality restoration website at ladwp.com/waterqualityor call the LADWP Water Quality Hotline at (213) 367-3182 between 8:00 a.m. and 4:00 p.m. or they can call 1-800-DIAL-DWP for 24-hour assistance.
