Apparatus and a method for installing a tubular liner in a pipe, as in repair of underground sewer piping. A feeder is of flexible material, which may be similar to that of which the tubular liner is made, and is connected to an end of the tubular liner. The feeder includes a throat portion through which a quantity of inside-out tubular liner is drawn into the feeder by fluid pressure within the feeder and beyond the throat, and the tubular liner is thence urged by fluid pressure into the pipe where it is to be installed.
