Heat the Fitting — Disconnect the Old Sillcock (Sweat Joint)
Part of project
How to Replace a Frost-Free Outdoor Spigot (Sillcock) · Step 4 of 11
In this video
Wearing heat-resistant gloves, firmly grasp the brass PEX tee fitting with a pair of channel lock pliers. Ignite a propane torch and carefully apply the flame to the exterior of the brass fitting, focusing on the area containing the stuck piece of PEX pipe. Rotate the fitting or move the torch to ensure even heating around the entire circumference. Continue heating until the PEX pipe begins to soften, melt, and smoke, indicating it's ready for removal.
Goal: Melt the PEX Pipe
- Do not point the torch flame directly at the PEX pipe for an extended period, as it can cause it to ignite and produce more noxious fumes.
- Continuous movement of the flame around the fitting prevents overheating a single spot and ensures the PEX loosens evenly.

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.
