What shapes water heater trouble in Braintree
In a condo or apartment building
About 22% of Braintree homes are in buildings with five or more units. If you own a condo, your unit's water heater is usually yours, but check your association's rules, since some buildings share a central system. If you rent, call the landlord or manager first.
A leak in a stacked building can reach the unit below fast. Shut the cold valve on top of the tank and let your neighbors and the building manager know.

Tri-Town water
