This watering sprayer is a nearly indestructible device, made entirely of metal and designed for professional use. With the generously sized shower head, it distributes a penetrating but gentle rain shower over your plants. The connection to the garden hose is made by the included sturdy brass plug, which is compatible with standard hose couplings (brass or plastic). Just please note the following before connecting your watering sprayer for the first time: To ensure proper operation, the water pressure at the unit should be at least 1.5 bar. Since inclines and declines in the garden area, the use of a very long garden hose (or simply too small a diameter of the water pipe) can have a pressure-reducing effect, the water pressure at the tap should better be a little higher, depending on local conditions.
