A sprinkler tap connects optionally to either a fitting of underground piping or an existing sprinkler head of an automatic sprinkler system and includes a generally T-shaped body having a fluid flow passage extending between an open bottom end and a first output port at a top end. A second output port communicates with the fluid flow passage between the bottom end and the first output port. The first output port is adapted for receiving either a male or female sprinkler head nozzle or, alternatively, a plug. A quick connect fitting on the second output port allows for easy connection and disconnection of a hose. The opposite end of the hose may be attached to a portable sprinkler device, a hand held spray nozzle or other water dispensing device. The quick connect fitting has an internal stop valve that closes when the hose is disconnected from the device, thereby preventing wasteful discharge of water from the second output port.
