To raise the height of an outdoor water faucet, the best thing to do would be to get an extension for the existing pipe that will bring the faucet to the height desired. Remember to turn off the source of the outdoor faucet before starting this project. Remove the faucet valve, screw in the new pipe, replace the faucet valve. Sealing the ends of the new pipe with plumber's tape is also a good idea.

The easyest way to stop your leak is replace or repair your outside faucet if its a freezeless one. (just make sure your outside faucet has grade to drain the water out after you shut it off)
