It is a long time ago since you posted your comment, but I will answer anyway, as I believe it can help many people. I live in Brazil, and here we have had many issues like you described, due to changes in the pressure of water supply company. It makes that much air comes into the piping, and when this trapped air comes to the home meters, it is registered ...
You should check to see what the water pressure is coming from the water main. A screw-on water pressure gauge can be connected to your garden hose connection to find out what it is. Ideally you would want to see a water pressure between 60 and 80 psi. If your pressure is significantly lower than 50 psi from the main, then you will have issues with having ...
There are no residential codes around pipework and electric distance other than they cannot support each other (touch). Electric live wires are enclosed. Pipework is enclosed. They can be basically as close as you want them to be without them touching.
Tankless water heaters have a flow switch and temperature sensors. Flow switch activates the water heater when water is flowing and the temperature sensors control the amount of heat delivered. Perhaps the flow switch is stuck on.
