520	3 |a"Dranjer Corporation patented the concept of a floor drain with a counterbalanced valve/seal assembly to prevent the flow of sewer gas if the conventional P-trap dries out. It was anticipated that this design would function as a backwater valve and that it could sufficiently reduce trap evaporation to eliminate the requirement for trap primers. Field trial model XN-3 floor drains were produced for testing and monitoring. Testing and monitoring was done to assess the ability of the device to perform as a floor drain, meet the requirements of the proposed applications and to comply with the requirements of CSA Standard B79-94 "Floor, Area and Shower Drains, and Cleanouts for Residential Construction". Testing, monitoring and reporting were done by an "at arms length" engineering consultant"--Abstract.
