Anti-frost hose bibbs (e.g. this product) move the spigot valve inside your house to keep them from freezing. For proper installation the bibb needs to be installed at a downwards angle - mine did not include the washer mentioned in the instructions and so I designed one.
The angle of this washer is 5 degrees. Autodesk Fusion file included for adjusting dimensions to your specific spigot.
