Before You Begin
Before you start the installation process, there are a few things you’ll need to do to prepare:
Gather Your Tools and Materials: You’ll need a variety of tools, including a pipe wrench, adjustable wrench, screwdriver, tubing cutter, and tape measure. You’ll also need materials such as plumber’s tape, pipe joint compound, and flexible water supply lines.
