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.

LADWP lifted the boil water notice for Granada Hills and Porter Ranch, confirming tap water is safe after tests.
