Biltmore Forest Backflow (RPZ) Installation Specifications.
Any backflow currently in service that is located below ground will be allowed to remain below ground until the RPZ fails its annual inspection and can not be repaired. If a new backflow device (RPZ) is installed, at any time, it must be installed above ground.
Don't forget to remove your backflow before cold weather to prevent freezing.
