I cannot access where the main water line enters into the building. Where should I place H2know?

In situations where access is not available near the intake, installing H2know on the cold water intake to the hot water heater is possible. You can identify the cold water pipe because it usually has a shutoff valve and the pipe will be cold. Be careful not to touch your hand on the hot pipe, tanks can heat water to more than 140 degrees Fahrenheit. In addition to the hot and cold pipes, if your tank is heated by gas, you will have a third pipe for the gas.
