A pipe liner re-flaring system and method for use with a water pipe containing a pipe liner. The pipe liner re-flaring system and method generally include a compression coupling comprising a pair of female compression fittings and a dual ended male compression fitting connected between the female compression fittings. The female compression fittings are adapted to fit over and secure the lined water pipe and a second pipe to be joined with open ends of the pipe liner and the pipe to be joined in direct contact within the male compression fitting. A pipe liner expansion tool and a pipe liner flaring tool are used to expand and re-flare the open end of the pipe liner so that the pipe liner is in contact with an inner wall of the compression coupling to prevent leakage and contact between fluids flowing in the pipes and the material of the pipes and compression coupling.
