How to Replace a Frost-Free Faucet: A Comprehensive Guide for Beginners
Understanding Frost-Free Faucets
Frost-free faucets, also known as freeze-proof faucets, are designed to prevent water from freezing inside the pipe or valve and causing damage. They achieve this through a combination of features, including a long valve stem that extends into the warm interior of the home and a self-draining design that prevents water from accumulating in the faucet.
Reasons for Replacing a Frost-Free Faucet
Despite their freeze-resistant design, frost-free faucets can still freeze and rupture in extreme cold. Additionally, they may need to be replaced due to wear and tear over time.
Materials and Tools
Before you begin, gather the necessary materials and tools:
Materials:
- Replacement frost-free faucet (same size as the original)
- Plumber’s pipe-seal tape
- Exterior caulk
Tools:
- Screwdriver
- Utility knife
- 2 Tongue-and-groove pliers (channel-locks)
- Caulk gun
Step-by-Step Instructions
1. Unfasten the Faucet
- Locate the mounting screws holding the faucet to the exterior wall and remove them.
- If the faucet flange is sealed with caulk or paint, carefully cut through the seal with a utility knife.
2. Disconnect the Faucet
- Inside the house, identify the pipe fitting where the faucet connects to the water supply pipe.
- Grasp the fitting securely with one pair of tongue-and-groove pliers to prevent it from turning.
- Use another pair of pliers to turn the faucet pipe counterclockwise until it disconnects from the fitting. Be prepared for some water to drip.
3. Remove the Faucet
- Pull the faucet out from the wall on the exterior side.
4. Install the New Faucet
- Take the new frost-free faucet and wrap plumber’s pipe-seal tape around the threads clockwise.
- Insert the faucet pipe through the wall opening from the outside.
- Inside the house, thread the faucet pipe into the fitting on the water supply pipe. Tighten the connection securely with tongue-and-groove pliers.
- Double-check that the faucet spigot is facing down.
5. Finish the Project
- Turn on the water supply slowly and check for leaks.
- Secure the faucet flange to the outside of the wall with galvanized screws.
- Apply a bead of exterior caulk around the faucet flange to create a watertight seal.
Troubleshooting
If your frost-free faucet is freezing, there are a few potential causes:
- Extreme cold temperatures
- Insufficient insulation around the faucet
- Malfunctioning self-draining mechanism
To prevent freezing, consider adding insulation around the faucet or wrapping it in heat tape. If the self-draining mechanism is not working properly, it may need to be replaced.
Additional Tips
- When measuring for a new frost-free faucet, remove the old faucet and bring it to the store for an exact match.
- If your old faucet is soldered in place, you may need to hire a plumber for the replacement.
- It’s helpful to have an assistant outside the house to watch for leaks as you tighten the connections from inside.
