A tap tower and keg tap alert system combination for alerting bartenders when a beer keg is running low or empty includes a coupler that is configured to selectively engage a beer keg, a first hose coupled to the coupler that is in fluid communication with the coupler, and a sensor coupled to the first hose. The sensor utilizes a flow sensor to detect flow volume and pressure of beer in the hose. A battery is used for power. A second hose is coupled to the sensor and a tap faucet of a tap tower. An indicator is coupled to the sensor that is in operational communication with an LED light coupled within the tap tower. The LED light is configured to shine green, orange, and alternatively, red, when pressure and volume detected indicate the beer keg is good, nearing empty, and empty, respectively.
