The 4000/1 Rainwater tank from Gardena is a high performance unit with low power consumption and is designed to help save you water in the garden. In conjunction with a water butt or water tank for collecting rainwater, it enables the harvested water to be quickly and effectively pumped out into other areas of your garden- this saves you from having to go back and forth with a watering can, but is also ideal for feeding directly into certain sprinklers (like the Gardena AQUA) which only require a low bar pressure in order to work effectively.
