Preparation and Safety Guidelines
- Sawzall with demo blade
- PB Blaster/penetrating oil
- Wire brush
- Pipe wrench
- Union fitting
- Nipple
- Pipe dope
- Hammer
- Pry bars
- Measuring tape

- Carefully remove the rusted pipe sections from the fittings. This might require using pry bars and penetrating oil to loosen the rusted joints.
Remove the Old Pipe Clean the Threads
- Use a wire brush to thoroughly clean the threads of the remaining pipe sections to ensure a good seal with the new fittings.
Clean the Threads Prepare and Install the Union Fitting
- Apply pipe dope to the threads of a nipple and screw it into the looser end of the pipe.
- Apply pipe dope to the threads of the union fitting and screw it onto the nipple. Tighten securely using a pipe wrench.

- Always use pipe dope: Apply pipe dope to all threaded connections to ensure a watertight seal.
- Be careful when cutting near threads: Avoid damaging the threads when cutting the old pipe.
