Karl, At the site visit yesterday it was determined that a backflow device is needed on the fire line. This comment can be addressed by either: 1. Removing the combination meter that is currently on the fire service and replacing it with a double check detector apparatus. The meter on the device can be a Hersey or Neptune disc meter and shall have either a touch pad or radio read transmitter. If a radio read transmitter is decided upon, please contact Jerry Davis for specifics. 2. Placing a double check valve assembly on the fire line inside the building or exterior to the building in a new vault. In accordance with State regulations a design shall be submitted for the device by a licensed fire protection consultant. The device will need to be installed and the fire line looped prior to a CO being issued. I will let Building Inspection know that Public Works is clear with proceeding with a permit for the renovations of the natatorium. If you have any questions, please feel free to contact me. Thanks, Clay Barnett, P.E. Town Engineer Town of Addison 16801 Westgrove Drive Addison, TX 75001-2818 Office: (972) 450-2857
