Next inspect the low flow indicator if it is moving you have a leak.
Water meter leak indicator not moving.
It been 3 months and yesterday i had a plumber check it and open the water flow.
All have separate water meters located on the pavement outside.
Observe the water meter readings.
He said there was no leak but he only checked for 10 minutes and then closed the main valve again.
The indicator on the meter was not moving.
Water meter show constant usage but no leak but.
If it is not moving you must have a leak beyond the internal stopcock therfore turn the stopcock on again and check the meter to see if anything is registering.
Sometimes it s in the middle of the sweep hand sometimes off to the side.
I turned off the water from the main valve to the house and the meter stops turning.
The low flow or leak indicator moves slowly for small leaks and faster for larger ones.
If it is moving you likely have a leak.
It is usually but not always red as indicated in the photos below.
After triple checking that no water is being used in or around your home observe the sweep hand if it is moving you have a leak.
It moves very slow when all water in the house is not being used.
My water meter has a small red water flow indicator.
As stated before almost all meters have a leak indicator that moves with even he smallest flow.
Hj az i suppose it is possible but since it is such a rudimentary device it is almost impossible for it to fail.
The water was shut sometime in between however the water was not drained.
If you have one of the more modern meters there will be a small black disc in the centre behind the glass that.
That tells me the leak is in the house not between the meter and the house outside.
It is possible to have a small drip leak that is not measured by the meter.
It may be a triangle star wheel or dial.
