US Patent 7726585 External chemical distribution system and method

A chemical distribution system affixes flexible tubing (50) along exterior surfaces (52) of a dwelling (12) and along structures (16) external to the dwelling. The tubing is attached to the exterior surfaces with clamps (54) and exposed for maintenance. The clamps are form-fitted to the tubing. Spray nozzles (58) are inserted into the openings in the tubing for dispensing a chemical solution. The openings can be pre-formed or cut into solid tubing at during installation. A connector (42) has one end coupled to a hose for receiving the chemical solution and another end coupled to the tubing. The fixed distribution system provides for precise and even application of the chemical solution with minimal operator intervention.
