  • Conduit repair system
    Patent number: 9435480
    Abstract: A method and apparatus for repairing a leak in a curved section of plumbing includes a conduit repair liner that has a central section made of polyethylene terephthalate and optionally reinforced to conform to a section of plumbing that has up to a 90 degree bend. The conduit repair liner has straps with an end of each of the straps at an edge and a distal end of each of straps has a section of hook and loop material. The conduit repair liner is wrapped around an inflatable carrier after saturating with a bonding agent then both are positioned within the curved section of the plumbing and the inflatable carrier is inflated. After the bonding agent cures, the inflatable carrier is deflated and removed, leaving the conduit repair liner evenly adhered to the inside surfaces of the curved section of the plumbing.

  • Conduit repair system
    Patent number: 9163771
    Abstract: A method of repairing a crack or leak in a curved section of plumbing includes wetting/saturating a conduit repair liner with a bonding agent (e.g., epoxy). The conduit repair liner has straps with an end of each of the straps at an edge of the conduit repair liner and a distal end of each of straps has a section of hook and loop material. After saturating is complete, the conduit repair liner we with the bonding agent is wrapped around an inflatable carrier and then both are positioned within the curved section of the plumbing. Now, the inflatable carrier is inflated such that the conduit repair liner adheres evenly to the inside surfaces of the curved section of the plumbing. Next, the inflatable carrier is deflated and removed, leaving the conduit repair liner evenly adhered to the inside surfaces of the curved section of the plumbing.
