With a GARDENA water distributor, you connect multiple accessories to 1 faucet. That way, you water various places in your garden at the same time. For example, water your lawn and your flowerbeds with a GARDENA 2-way distributor. With a GARDENA 4-way water distributor, you even connect 4 accessories like garden hoses or water controls. You can open or close every connector separately with the buttons. That way, you use all accessories at once or separately of each other.
