Frost Free Faucets
A frost free faucet is designed to prevent water from freezing inside the pipe or valve and damaging it. Despite this, there are times when frost can damage the frost free faucet and it will need to be replaced. Wear from frequent use is another reason why a frost free faucet will break and need to be repaired or replaced. You may want to consider which is easier and faster to replace or to repair the frost free faucet.
If you decide to replace a frost free faucet you will need to know the length... of the existing faucet. Determining the size can be tricky because you have to see the whole thing to measure the faucet. It can be many times easier to just remove the old faucet and bring it to the home improvement store with you to get one that is the same size.
The following steps will show you how to remove and replace a frost free faucet.Continue to 2 of 6 below.

Shut Off the Water
Begin by shutting off the water to the house. It is a good idea to double check that the water is off before you try to remove the frost free faucet. Be prepared to have the water turned off for a while, especially if you will need to head out to buy the replacement faucet.Continue to 3 of 6 below.

Unfasten the Faucet
Remove the screws that are holding the faucet to the house. These anchor screws are in place to restrict movement and they will prevent you from disconnecting the other end of the faucet. Remove anything else that will prevent the frost free faucet from turning such as caulking or paint.Continue to 4 of 6 below.

Disconnect the Faucet
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... 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.Continue to 5 of 6 below.

Install the New Faucet
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... 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.
