According to one resident, the fire alarm went off at around 1:10am. Two firetrucks responded. While everyone was standing outside, House Adivsor Batia Epelbaum said that it probably had something to do with the flooding in her apartment, located on the first floor of the dorm. Batia then said something along the lines of, "It's going to be a while, you should find somewhere warm to go." Residents were let back in at 2:10am, but security told them they would not have hot water for a day or two.
This morning, residents found a sign posted in the lobby saying the hot water would return at noon today. Dorm President Samantha Garcia '13 also sent out an emailing saying, "So just a warning I have been told that we may not have hot water until noon. Just a heads up!"
Update: Here's what happened, according to Garcia: "A pipe connector that from years of use got blocked up, burst, and water started flooding into Batia’s apartment. There are two reasons why the fire alarm might have gone off. The first is that water may have seeped into the basement and set off the fire alarm there or steam from the hot water that was coming out may have set it off."
