Automatic watering is a simple network of pipes that carry the water around the garden, and outlets that deliver it to the plants. Most systems can be installed in a few hours and all can be extended as your garden grows.The Hozelock automatic watering system has been designed to be easy as possible to understand. The system is split into three sections, each is in colour coded packaging. A - TAP (Red) Connects the system to your tap. B - Pipeline (Amber) Takes water all around your garden. C - Dripper (Green) Use to water your plants and borders.
