Our back patio outdoor hose spigot is leaking at the fixture. We have had this happen before and we remember adding some graphite packing material inside the faucet behind the handle. Does that make sense?? We are wondering if we need to shut off the water to the house before we take the handle off to get to the old graphite inside the faucet. We can't remember if we had to shut the water off last time.

Thanks for any help with this!
