Product description contains all the important components for the successful installation of the GARDENA Pipeline system. Water is supplied from the tap via the Connection Set to the underground supply pipes. The two included Water Connectors provide connection points for a hose, or the separately available GARDENA Pipeline accessories, such as the Pop-up Oscillating Sprinkler or the Water Tap. Like all other system components, the Water Connector is permanently installed. This gives you convenient access to water anywhere in the garden, exactly where you need it, just like an indoor tap. The Water Connector is equipped with an automatic water stop. This means you don't have to walk to the tap and hardly any water is lost when connecting or disconnecting accessories. As soon as you shut off the pipeline system, any remaining water is automatically drained via the Drain Valve. The Drain Valve is installed at the lowest point of the system and ensures that the system is frost-proof. Both the Connection Set and the Water Connectors are equipped with a filter that protects them against dirt. The filters are easy to remove and clean under running water. All components of the Pipeline Set are of high quality and therefore UV-resistant. The system can be expanded indefinitely with Pipeline components. The Pipeline Starter Set is a quality product manufactured in Europe. Water where it's needed. Easy access to water: underground supply pipes.
