The city of Norwalk is dealing with fire and water problems.
Investigators are trying to figure out how a fire at 415 Pine Avenue started on Sunday.
They were back on the scene Monday looking for clues but they say it will be a while before they have any answers.
Near the fire scene, one of the city’s main water lines ruptured.
The break didn’t affect the firefighters but it did force officials to cancel school on Monday and issue a boil order.
The main has since been fixed and water samples are being tested before the boil order can be lifted.
