Apparatus for repairing a pipeline and method for using same

A method for repairing a lateral sewer pipe which joins a main sewer at a pipe junction, said method comprising:

• forming a liner assembly having and elongated main liner tube and an elongated lateral liner tube, said main liner tube having first and second main liner tube ends, said lateral liner tube having a first lateral liner tube end connected to said main liner tube and having a second lateral liner tube end;
• impregnating said main liner tube and said lateral liner tube with an uncured material capable of curing and hardening;
• attaching a first line to said first main liner tube end;
• attaching a second line to said second end of said lateral liner tube;
• threading said second line into said lateral sewer pipe;
• pulling on said first line to pull said main liner tube of said liner assembly to said junction;
• pulling on said second line to pull said lateral liner tube of said liner assembly into said sewer pipe;
• inverting main bladder tube into said main liner tube and inverting a lateral bladder tube into said lateral liner tube;
• inflating said main bladder tube within said main liner tube to spread said main liner tube outward in a radial direction into contact with said main sewer pipe;
• inflating said lateral bladder tube within said lateral liner tube to spread said lateral liner tube outward in a radial direction into contact with said lateral sewer pipe;
• permitting said uncured material impregnated in said main liner tube and said lateral liner tube to cure and harden;
• removing said main bladder tube and said lateral bladder tube from said main liner tube and said lateral liner tube respectively.
