VAC-A-TEE is a trenchless cleanout system and here is how it works. The lateral is located typically by a mainline camera that projects a satellite camera up into the lateral pipe. The satellite camera contains a sonde that transmits a frequency which can be pin pointed from ground surface. Once the lateral has been located, a bore hole about 20" in diameter is created by using water to cut the soil and a vacuum truck to remove the soil into a tanker. This is referred to as vacuum excavation. Once the lateral pipe has been exposed through vacuum excavation, a special PVC saddle is prepared by applying PVC epoxy to the underside of the saddle. The saddle with a riser pipe is then introduced into the hole and the saddle is snapped onto the lateral pipe. The epoxy cures and forms a new water tight cleanout. The riser pipe is filled with 6 feet of water performing an ex-filtration test. A diamond core saw is then used to cut open the crown of the pipe. The VAC-A-TEE system will work with a variety of pipes including VCP, Orange Burg, PVC and Cast Iron.
