When water is being drawn into the home it is normal to hear some low ticking at the meter, but it should not be loud enough to be disruptive.  A meter makes a certain amount of noise due to its moving parts.  When water comes into the meter it pushes a piston around a fixed point which in turn moves a magnet that moves a dial.   If your meter is making enough noise to cause a disturbance in the dwelling then please call our office at (508) 533-3208 and we will send a technician to inspect your meter and potentially swap in a new one.
