Question
Can I use white teflon packing? Is there a washer in the packing nut, and should it be replaced?
Community Answer
Yes. White teflon packing string is preferred. And yes, if your faucet has a washer under the packing nut, it should be taken to the store and matched up to a replacement.

Question
What if the main water shut off valve is leaking?
Community Answer
Then you have to have to turn the water off at the street. You would either have to contact the water utility for this, or they may allow a master plumber to do so.
