This hydrant was in service in Oakland, CA from the 1880s until 2000 when it
was removed during a water main replacement.
The plug on top was for a "street washer." Street washers were common in
neighborhoods where houses didn't have indoor plumbing. The street washer was
a large hose bibb with a weighted handle where residents could fill buckets
for household use and for their livestock. (See top view, image 0631b.)
(Hydrants in city parks were often painted green.)
