This is a new apparatus and method for cleaning debris from the inside of a foundation drain tile, the drain tile being in the immediate proximity of the perimeter of a building structure. A rocket nozzle which is in fluid communication with flexible tubing and a high pressure water supply, and a foot pedal control valve is used for starting and stopping the fluid flow. An opening in the tip of the nozzle enables pressurized water to be discharged through the tip in a forward direction. At least two apertures are disposed along a nozzle recess. The tubing is secured to the nozzle and is in fluid communication with the nozzle. An on-off foot pedal control valve is used to start and stop the water flow into the tubing and into the nozzle. As pressurized water is supplied to the nozzle and projected through the apertures, the nozzle is propelled in a forward direction through the drain tile. The flow of the pressurized water through the nozzle causes the pressurized water to be projected through the opening in the nozzle tip. As the nozzle is propelled through the drain tile, the water flowing through the nozzle tip is continually directed at the debris at sufficient force to separate the debris from the drain. To assist in cleaning the drain tile, a series of cleanout pipes are installed near the junctures of the drain tile and conventional pipes located underneath the basement floor. |
