How to Replace a Frost-Free Outdoor Spigot (Sillcock) · Step 11 of 11

Return to the main water shut-off and turn it back on slowly. Go back to the sink and carefully inspect the new valve connection for any signs of leaking. If the connection is dry, open the new valve by turning its handle counter-clockwise. Finally, turn on the faucet and check the supply line connection and the valve itself one last time for any drips. If everything is dry, the job is complete.
Goal: Test the New Installation
- If you have a leak from the supply line connection, you can try applying a small amount of plumber's tape to the threads before re-tightening.
- Turn the main water on slowly to avoid a water hammer effect, which can damage pipes.

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.
