A temporary sealer for pipe repair and construction includes a sealing head, and a breakable film. The sealing head has a tubular shape and a size and shape corresponding to an inner diameter of a pipe. The breakable film is formed at the sealing face of the sealing head, wherein the breakable film forms a water barrier for temporarily restricting a flow of water passing through the sealing head within the pipe when the sealing head is slid into the pipe. The breakable film is inevitably torn apart in responsive to a predetermined water pressure for enabling the water flow passing through the sealing head within the pipe. Therefore, it not only provides a way to efficiently block the water flow when the water pipe needs construction, but also provides an apparatus involving the flow system when the water pipe system is finished with construction.
