Leak detector on water meter spins back and forth
Posted: Wed Mar 04, 2020 9:34 pm
Every once in a while I check my water sub-meter (I am in a park where each home has a sub-meter) to see if I have a water leak. I recently got a new sub-meter, which has the red triangle leak detector dial (my old one had the blue wheel type dial). Today was the first time I checked for a leak since I got the new meter, and I was shocked to see the red triangle jump back and forth. I never noticed this in all the years I checked when I had the blue wheel. When the red triangle moves, whether it moves back or forth, it does not move slowly but jumps at various speeds and in various intervals, sometimes 2x in a minute, sometimes not at all for several minutes. I turned off all water supplies inside my home and it still jumped. Only time it stopped jumping was when I turned off the main water valve (which is located right below the sub-meter). When I actually do use water, the red triangle moves at a steady speed. Anyone know what it means when the dial jumps back and forth? And with the thing randomly jumping back and forth, how am I going to be able to tell whether I have a leak or not? Any input is appreciated!
