    Locate the frost free faucet from under the house if possible. Sometimes the connection for a frost free faucet it will be run into the wall in which case you may have to cut an access panel to get to it if one is not already in place.

    You will need at least two pairs of pliers, adjustable wrenches or something similar to disconnect the faucet. With one of the pliers supporting the water line and the other on the faucet unscrew the valve from the housing. There are times when the faucet is...MORE soldered to the water line in which case you will not be able to unscrew it. If this is the case the line may have to be cut off and an adapter installed for the repair. A shark bite or gator bite fitting would make for a great repair adapter in this case.

    Apply plumber's tape to the threads of the new frost free faucet. From the outside wall feed the threaded end of the faucet into the opening. Screw the new valve back into position being careful to not cross thread it. It may be helpful to have a second person on the outside of the house telling you when the faucet is pointing down (or you could draw a mark on the faucet indicating which way is down before putting it in the wall).

    While you tighten, be sure to hold against the water line...MORE adapter to keep it from moving. Once again it is best to use two pliers, one on the faucet and one on the water line. Turn the water on and check the frost free faucet for leaks (this is another instance when a helper is useful). If there are no leaks the last thing to do is to screw the freeze proof faucet to the wall to anchor it.
