ABSTRACT:
A waterlock comprises a threaded cap nut (11) which fits tightly over the threaded end of a water pipe (15) or faucet (21). A sleeve (10) fits over the cap nut to prevent access to the nut. The sleeve is free to rotate about the cap nut such that turning the sleeve will not turn the nut. The nut has a flat end with a central hole (16), while the sleeve also has a flat end with a central hole (14). A stem (12) with a flange (17) at its base extends outwardly through the holes. The flange secures the stem to the nut by engaging the inside of the nut. An orthogonal hole (18) in the stem accepts a padlock (20) which prevents the sleeve from being removed from the cap nut.
