During periods of no rainfall, if the rainwater tank runs out of water, there are options to ensure a continuous water supply. The system is designed to prevent running out of water, but if it does happen, there is a mains water top-up supply available. This can be achieved through a gravity-fed mains water supply to the underground tank, a direct mains water supply to a loft tank (in the case of a header tank installation), or a modern pump kiosk with a float switch. These mechanisms detect the water level and automatically redirect mains water to the appliances until the underground tank is refilled during the next rainfall event. So, even during periods without rainfall, there is a backup solution in place to provide water to the appliances.
