WARNING! This procedure is mildly dangerous and potentially very costly if not performed properly, with great care and consideration, and due diligence. WARNING!
WARNING! This procedure involves completely draining an in ground swimming pool, something that is recommended only in a few circumstances. If not performed properly it could, at a minimum, ruin your liner (approx. $2000) and at most require your pool to be rebuilt entirely (approx. $15000). This procedure is only applicable to certain pools based on location. If you have any doubts as to whether to proceed please consult a pool construction professional. WARNING!

By reading and using the information in this instructable you agree that you take full responsibility for any damages or injuries caused to your person or property or anybody else's person or property by performing this procedure either properly or improperly and hereby release me from any responsibility for said damages.
I will attempt to make these instructions as general as possible and try to cover as many different scenarios as possible. Bear in mind, however, that they are based on my personal (novice) experience and my observations of the initial installation of my pool's liner by professionals. As such they will lean heavily toward my specific circumstances.
