Humming noise stops when out of house for several days.
I hear a hum throughout the house that is constant. However, I noticed that when when I return to the house after a vacation it takes about 2 days before the noise returns. I feel it is water related but don't know how. Can you help me with any suggestions as to what is causing the humming to return after being out of the house for several days.

We also are losing water somewhere but have not been able to identify where. I would like to know how you found the leak.

I know the noise is coming from inside the house- I hear it as soon as I enter the garage. We have systematically turned off applicances, lights, TVs, keeping each off for at least overnight put have not been able to isolate the problem. Have done the same with toilets, faucets, showers, etc. I can't figure out why the noise goes away after we are out of the house for two days, yet is still there when I wake up every morning and nothing is being used during the night. I'll try things like door bell and remote control.
