What shapes water heater trouble in Rockland
Water heaters in multi-family houses
About 20% of Rockland homes are in buildings with two to four units, and about 30% of all homes were built before 1940. In a two- or three-family house, each unit may have its own heater in a shared basement, so the first job is finding which tank is yours.
If you rent, the landlord is usually responsible. If you own and live in one unit, check all the heaters while the plumber is there.
National Grid gas
About 58% of Rockland homes heat with gas, and the state's gas provider map lists National Grid for Rockland. If you smell gas, leave the building, then call 911 or National Grid at 1-800-233-5325 from outside.
Water shared with Abington
Rockland's water comes from the Abington & Rockland Joint Water Works, which serves both towns.
