• a single liner assembly comprising a main liner member capable of everting within the main pipe and one or more lateral liner tubes combined with and extending from the main liner member, each lateral liner tube capable of everting from within the main liner member to a position within one of the one or more lateral pipes;
• wherein the single liner assembly is moveable between a position outside the main pipe and the one or more lateral pipes to an everted position wherein the main liner member is within the main pipe and the one or more lateral liner tubes is within the one or more lateral pipes;
• wherein the main and lateral liners comprise a resin absorbent material;
• and
• wherein each lateral liner is sealed to the main liner member.

A method of repairing pipes including a main pipe extending between a first and second manhole and one or more lateral pipes extending from the main pipe, the method comprising:

• providing a single liner assembly comprising a main liner member and one or more lateral liner tubes extending from the main liner member, the one or more lateral liner tubes sealed to the main liner member, and capable of everting from within the main liner member to a position in at least one of the one or more lateral pipes;
• impregnating the liner assembly with a material capable of curing and hardening;
• positioning the single liner assembly inside the main pipe and at least one of the one or more lateral pipes by everting the main liner member through the main pipe and everting at least one of the one or more lateral liner tubes from within the main liner member into at least one of the one or more lateral pipes;
• and
