How do I fix a leaking sillcock or spigot?

This topic is available here on The Repair-Place forum
My outside spigot is dripping on the inside of the house. Could you give me some direction on how to fix this?
OK first you need to do is find the shut-off on that line to the outside faucet. Then examine the piping you have. Let me know how it goes from the outside of the house to the inside. Is it a straight line or are there elbows when it gets inside.
Then let me know what kind of plumbing tools you have and we can see if it will be cost effective to do it. Some of the tools needed are pricey.
To install a new faucet, cut (with a pipe cutter only) the old pipe inside the house where convenient. Purchase a new sillcock of the type needed for your area (freeze proof if needed). Push the new valve through from the outside and then measure the distance to the old pipe. Don't forget to add where it goes into the end of the valve. Put a coupling onto the old pipe and test fit all. If all looks ok then proceed to sweat away. I would remove the valve, and sweat on the piece of pipe to the valve first, then put the valve with the pipe into the hole through the house, then into the coupling. Lastly sweat the coupling both sides. If you have never sweated a joint I would practice a few times first. Here is some tips:
1-using a sanding screen (comes in a roll) sand the last inch of the pipe going around the pipe until bright copper.
2-using a wire brush that is the correct size for the pipe, clean the inside of the fittings by twisting back and forth for about 10 times.
3-Using flux and a small brush coat all surfaces
4-put all together
5-heat with propane torch from the bottom of the fitting. The heat will travel up and will also heat the pipe too. Move the flame around a little, don't just hold it in one place or you'll overheat.
6-touch the end of the solder (95-5) no lead please to the top side which is away from the heat. If it is hot enough the solder will melt and travel into the joint all the way around.
7-use a rag and CAREFULLY wipe the solder going around the pipe. The solder is HOT and will drip a bit so don't get burned. Don't use a wet rag. The water will turn to steam and burn.
Hope this helps!!
turn off water to outside. remove all connections and look for washers. replace all washers including one in anti-syphon seat. might as well replace washer in outdoor watering hose- male end. if that doesn't stop leak, call professional.
Did you ever find the leak? It could be the water is just leaking around the hole where the pipe comes out of the house. Unscrew the 2 screws that hold the silcock to the exterior, pull it away from the house a little (like a 1/2" or so) and squeeze some caulk under there around the pipe as it goes into the house. That's where mine was leaking.

Good luck!
