Access Interior Plumbing by Cutting Drywall

What happens here

Move to the inside of the garage, directly behind the outdoor faucet. Identify the copper pipe connected to the faucet. Using a sheetrock saw, carefully cut a rectangular section of the drywall to expose the pipe connection point. The presenter advises taking precautions if a backup wrench is needed, as damaging the unsecured internal pipe can be problematic.

Goal: Gain access to the interior section of the faucet's pipe by carefully cutting and removing a section of drywall (sheetrock) from inside the garage.
