Disassemble the Sillcock — Remove Old Sillcock from Exterior
Part of project
How to Replace a Frost-Free Outdoor Spigot (Sillcock) · Step 5 of 11
In this video
Start the disassembly by using a flathead screwdriver to remove the central screw holding the handle in place. Once the screw is out, remove the decorative red label and pull the handle straight off the stem. Next, use an adjustable wrench to loosen and unscrew the outer packing nut, followed by the inner packing nut. Be careful to set aside the washer located between these two nuts. With the nuts removed, the entire stem assembly can be pulled out from the body of the sillcock.
Goal: Sillcock Disassembly
- Lay out the parts in the order you remove them. This will serve as a guide for reassembly.
- If the stem is stuck, you can gently tap the end of it with a pencil or similar object from the pipe-connection side to push it out.

FAQs
Is soldering really required for this project, and how difficult is it for a beginner DIYer?
While this project is rated beginner, the soldering step can be intimidating. With practice on scrap copper pipe first, a propane torch, and proper flux, it's achievable. The 6-hour estimated time accounts for careful work and ensures a watertight, durable connection.
What are the most important safety precautions I need to take, especially with a propane torch?
Always have a fire extinguisher or a bucket of water nearby when soldering. Wear safety glasses to protect your eyes, use heat shields if working near combustible materials, and ensure good ventilation. Crucially, confirm the main water supply is completely off and the system drained before beginning any work.
What's the most common mistake that leads to leaks after replacing a sillcock, and how can I prevent it?
The most common mistake is an inadequate solder joint or insufficient exterior sealant. To prevent leaks, ensure your copper pipes are clean, the flux is evenly applied, and the joint is heated properly for the solder to flow smoothly. After installation, apply a generous bead of high-quality exterior sealant like GE Supreme Silicone around the new sillcock where it meets the house.
How do I know which type of replacement sillcock to buy (e.g., PEX, FIP, different lengths)?
You must measure the exact length of your existing sillcock from the exterior wall to its interior connection point. Then, inspect your interior plumbing to determine the connection type – whether it's copper pipe for soldering, PEX, or a threaded pipe (FIP). This ensures you purchase a compatible replacement like the Woodford 1/2 in. PEX or Everbilt 3/4 in. FIP models.
