actually he would shut off faucets leave water supply open and then see if meter is moving
Not sure if that is a good idea unless the temps are warmed up or the house is being heated again
Correct. When i say main, i mean the meter outside, not any supply lines or valves in the house. Just turn the faucets off and leave everything else.
Definitely wouldn’t leave it that way for long; but it would be a quick way to see if there’s a leak somewhere
