The Los Angeles Department of Water and Power lifted a “boil water” notice Tuesday afternoon for Granada Hills and Porter Ranch, ending a weeklong episode that saw residents’ taps run dry or slow to a trickle. The DWP urged residents to flush out all water pipes and appliances before using the water. About 9,200 households in the west San Fernando Valley were affected by a water service outage that started last week after DWP workers discovered a faulty valve, according to the agency. The valve, which was installed in 1967 and located 20 feet underground, was stuck in a nearly closed position and could not be opened, which impeded the flow of water. … The agency said in a news release that those customers affected by the “boil water” notice would receive a $20 credit.
