How to Replace a Frost-Free Outdoor Spigot (Sillcock) · Step 6 of 11
This guide provides comprehensive, step-by-step instructions for removing an old or leaking frost-free outdoor spigot (sillcock) and installing a new one. The process involves shutting off the main water supply, disconnecting the old unit from the interior plumbing, installing the new sillcock, creating a watertight connection via soldering, and ensuring a leak-free result.

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.
