Many commercial building use sillcock key spigots in order to prevent some passerby from turning on the water on their building after hours , and leaving it on ……makes the city mad and costs them money . Their groundskeeper will of corse , have the key to it . The $3 spent at your local hardware store, on a 4-way key , might become very handy some day . They are small , and not bad to have in a B&E kit . Just Sayin
