Update: The flush and boil advisory has been lifted as of Wednesday, January 22. PWSA advises residents who have not run their water in recent days to flush their taps for at least one minute before using water for cooking or drinking.
The Pittsburgh Water and Sewer Authority has issued a flush and boil advisory for the Crafton Heights, Elliott, Esplen, Ridgemont, and Westwood neighborhoods.
PWSA said a 20-inch water main break near the intersection of West Carson Street and Steuben Street on Sunday evening caused the agency to issue the preliminary advisory.
"When there is a water pressure loss, contaminants can enter the drinking water," PWSA said in a press release.
PWSA said water pressure was restored at approximately 10:30 p.m.
Approximately 2,000 households are impacted. Water buffalos will be placed at Pittsburgh Fire Bureau Station #29, 2150 Noblestown Road; Pittsburgh Fire Bureau Station #31, 3000 Chartiers Avenue; and 725 Ridgemont Drive.
The agency instructs people to boil tap water for at least one minute prior to drinking or cooking.
The boil water advisory will continue until the authority can confirm the water meets or exceeds all state and federal water quality requirements.
