Abstract
A method for permanently repairing a fluid delivery system which may be above ground, subterranean, in and under concrete, or within a wall structure. The method comprises disconnecting the source and the discharge portions of the fluid delivery system. A resilient moldable tubing is threaded through the fluid delivery system. The first end of the tube is secured to the first end of the portion of the fluid delivery system. The second end of the tube is next secured to the second end of the portion of the fluid delivery system. The resilient tubing is then filled with heated fluid and pressurized to mold the tubing to the inside diameter of the fluid delivery system. The fluid is cooled to set the tube to the inside diameter of the fluid delivery system, and then drained before reconnecting the source and discharge portions of the fluid delivery system.
