A self-contained handheld drain clearing device is provided that uses compressed air to unblock various household drains and pipes. The device comprises an upper body and a lower body. The upper body includes a cylindrical chamber for housing a manual pump. A one-way inlet valve allows compressed air to enter a collection chamber, from which it exits to a storage chamber through a small hole in a piston. A trigger component is located in the upper body of the device, as is a pressure release safety component included for user protection. The lower body of the device primarily serves as a storage area for compressed air, containing an upper end and a lower end. The upper end contains threads for joining the lower body with the upper body, while the lower end contains a fitting for receiving various drain-sealing adapters.
