If BWSC or a property owner suspects that a meter is registering improperly, the meter will be tested by BWSC. The meter is the property of BWSC and if found to be defective, will be removed and a new one will be installed.
Most BWSC meters have a small red triangle that will only move if water is flowing through the meter, even if only a small amount. Meters do not move unless water is flowing.
To check for leaks, make sure no one in the building is using water or check the meter around 3:00 AM. If the red triangle is moving, you might have a leak and should check all plumbing.
If you still suspect you have a leak call Customer Service at 617-989-7800.
