Applicant 2. Manufacturing Facility 114 Mill Rock Road East 114 Mill Rock Road East Old Saybrook, CT, 06475, USA Old Saybrook, CT, 06475, USA Tel: Fax: Web: 3. Description The is intended to provide mechanical ventilation for new and existing Class 4 Sewage Systems as they are described in Part 8 Sewage Systems of Ontario s 2006 Building Code (the Building Code ). The is comprised of: a SoilAir Model 5BD, PVC backwater valve, a weather resistant heavy duty injection moulded lockable box, PVC Tee, SoilAir Float Switch, a blower, combination timer/controller and associated wiring, optional SoilAir PVC Baffle, optional SoilAir Pressure Switch, and associated tubing and other miscellaneous hardware. The manufacturer claims that it is a system that can rejuvenate leaching beds that have failed due to organic build up on the soil interface. The system operates by adding pressurized air to the leaching bed through the effluent distribution lines. The added air assists in the degradation of the restrictive biomat layer formed at the effluent soil interface. The backwater valve serves to prevent pressurized air from flowing backward to the septic tank. Page 1 of 7
