Put a Cap On It
We get it. NYC can be a hot, sweltering, concrete jungle.
While it may be tempting to cool yourself off by opening a nearby fire hydrant, illegally opened hydrants can release more than 1,000 gallons of water per minute, which can lower local water pressure and hinder the efforts of firefighters.
The good news is hydrants can be opened legally if equipped with a City-approved spray cap, which release only 20 to 25 gallons per minute. Adults 18 and over can get a City-approved spray cap, free of charge, at local firehouses.
If you observe a running fire hydrant, or are experiencing low or no water pressure, notify NYC 311.
