When the condensing unit is off, the water flow rate should taper off and eventually stop completely as the pressure within the system reduces. This is because the condensing unit is responsible for removing heat from the refrigerant, which helps maintain the pressure and temperature within the refrigeration system. When the unit is turned off, the pressure in the condensing coil decreases, leading to a drop in the refrigerant's ability to absorb heat. As a result, the system's overall pressure diminishes, causing the flow of water, which is often used to absorb heat during the condensing process, to stop. Without the condensing unit operating to maintain pressure and facilitate heat exchange, the driving force for water flow diminishes, leading to a complete cessation of flow over time.
