How to Replace a Frost-Free Outdoor Spigot (Sillcock) · Step 3 of 8
In this video
Using a power drill with a masonry bit, drill pilot holes into the concrete foundation at the marked locations. Re-insert the new sillcock and apply a bead of foam sealant or caulk around the flange to create a weatherproof seal. Secure the sillcock firmly to the wall by driving concrete screws into the pilot holes. To prepare for soldering, unscrew the packing nut and remove the entire long stem assembly to protect its rubber washer from heat damage.
Goal: Drill holes, seal, and securely fasten the new faucet to the wall.
- Failure to remove the stem unit before soldering will melt the rubber washer, causing the new faucet to leak.

FAQs
How do I ensure I purchase the correct length frost-free sillcock, and what happens if it's the wrong size?
Accurately measure the distance from your home's exterior wall to the interior plumbing connection point where the spigot will attach. The new sillcock's anti-siphon valve and shut-off mechanism must reside inside the heated portion of your home to prevent freezing. An incorrectly sized sillcock compromises its frost-free functionality, risking pipe bursts in cold weather.
I've never soldered before; how difficult is this step for a beginner, and what safety precautions should I take?
Soldering copper pipes is a common plumbing skill that is manageable for beginners with proper guidance and practice. Before working on the actual installation, practice on scrap copper pipes. Always wear safety glasses and gloves, ensure good ventilation, and have a fire extinguisher or bucket of water readily available when using a propane torch.
What are the most critical steps to prevent leaks after installing the new spigot?
The most critical steps are ensuring clean pipe surfaces for soldering, making strong, complete solder joints, and properly sealing the exterior flange. Use enough flux for good solder flow, heat the joint evenly, and apply a generous bead of exterior sealant around the flange. After turning the water back on, thoroughly inspect all connections for any signs of dripping.
What are the essential safety precautions when using a propane torch for soldering, especially near walls?
Always have a fire extinguisher or a bucket of water nearby when using a torch. Protect surrounding surfaces, especially inside walls, with a heat shield or fire-resistant cloth to prevent accidental fires. Ensure adequate ventilation, wear appropriate personal protective equipment like safety glasses, and allow all soldered components to cool completely before touching.
