How to Replace a Frost-Free Outdoor Spigot (Sillcock) · Step 8 of 11
In this video
Using a propane torch, heat the joints of the assembled pipes and fittings. Apply the heat primarily to the fitting, not the pipe. Once the copper is hot enough, touch the tip of the lead-free solder to the edge of the joint. The heat will melt the solder and draw it into the gap, creating a seal. Repeat for all connections on the hot, cold, and mixed lines. After soldering, wipe the hot joint with a damp cloth to remove excess flux.
Goal: Create permanent, watertight connections
- Ensure the area is well-ventilated when soldering to avoid inhaling fumes.
- Wiping the joint with a damp cloth after soldering not only cleans it but also helps prevent corrosion from the residual flux.

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.
