How to Replace a Frost-Free Outdoor Spigot (Sillcock) · Step 6 of 8
In this video
The sillcock is shown fully installed in a brick exterior wall. The process, which happens off-camera, involves drilling a hole through the wall, inserting the sillcock, and connecting it to the home's water supply (in this case, PEX tubing). The exterior flange of the sillcock is securely mounted to the brick, and a bead of white caulk is applied around the perimeter of the flange to create a weatherproof seal, preventing water from entering the wall cavity.
Goal: Plumbing Fixture Installation (Installing new plumbing fixtures.)
- Use exterior-grade silicone caulk for a durable, flexible, and waterproof seal.
- Ensure the sillcock is installed with a slight downward pitch to the outside, allowing it to drain properly and prevent freezing.
Used in this video
- Caulk gun (Caulk Gun: Manual) — Applying caulk around the sillcock flange for a weatherproof seal.
- Drill (Drill_Type: Cordless) — Drilling mounting holes for the sillcock flange and a through-hole in the wall.

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.
