calculating a rate of change of the at least one of water pressure in the water filter and flow through the water filter over time;
determining whether there is a system demand for water in response to an increase in the rate of change of the at least one of water pressure in the water filter and flow through the water filter over time; and
detecting a leak based on the increase in the rate of change over time when there is no system demand for water.
