“nosiy” outside faucet

[kase co]

my brother-in-law installed an outside faucet that hammers loudly everytime it is opened,,, I have never seen a faucet like this,,,,it has a metal/plastic cap on top that seems to have some sort of ball in it,,,(assumed it was a sort or water or pressure release) but wonder if it may be designed to actually MAKE noise whenever turned out (in order to alert homeowner as to its use by another by someone else) are there such valves/faucets?? – designed to produce noise when in usethanks for help
