Ensuring the irrigation of every part of the surrounding, external and internal, is essential, especially for those who love the garden. Thanks to the connections and the hydrants, performing these operations will be very easy: specifically, the connection ensures to have access to the water, thanks to the electricity, with a direct connection to a pipe. Between the pipe and the hydrant, a connection should be inserted, like a shut-off valve which allows automatically stopping the automatic water flow if the pipe is detached. Hydrants could be different kinds according to the needs. It’s available, for example, the unknotted hydrant, usable as a fixed point from where the water flow. The connection between the pipe and the grip is unknotted, namely, it could rotate itself, avoiding the twisting of the pipe and does not ensure the freedom of movement. The grip, moreover, could be underground, without causing any trouble to the grooming of the grass.
