Theft of water is a big concern for many homeowners as the cost of water has increased dramatically. When the Hose Bibb Lockout is installed on your outdoor tap, only the person with the key to the lock can access your water. This water faucet lock is very easy to install with 3/4" standard North American garden hose thread. The hose bibb lockout can not be removed by turning it: When turned it will just spin around. To get water to come out of your faucet when the hose bibb is installed you must first unlock the lock.
