A boil water advisory was lifted in Hoboken on Thursday after a large-scale main break.

Veolia Water officials say that residents should do the following before using their water.

• Run your water faucets for 3-5 minutes to flush your service connection and interior plumbing with water from the service main.

• Empty and clean your automatic ice makers and water chillers.

• Drain and refill your hot water heater if the temperature is set below 113 degrees Fahrenheit.

• Service connections with a water softener/cartridge filters should be run through a regeneration cycle or other procedures recommended by the manufacturer.

Officials say the break occurred when a contractor for PSE&G damaged an unmarked or mismarked water main while doing some gas line work.

Schools were closed, a hospital had to be evacuated and many businesses were forced to shut down as a result.

Hoboken officials are demanding answers from its water supplier, Veolia.
