How Long Does It Take to Install a Pot Filler Faucet?
Quick Answer
Installing a pot filler faucet takes 2–4 hours if a water line is already stubbed out. Running a new water line from scratch adds 4–8 hours, bringing the total to 6–12 hours.
Typical Duration
Quick Answer
The installation time for a pot filler faucet depends almost entirely on whether you already have a cold water supply line behind the wall at the correct height. If a line is already stubbed out, the faucet itself mounts in 2–4 hours. If you need to run new plumbing from an existing line, the full project takes 6–12 hours including wall work and finishing.
Installation Timeline by Scenario
| Scenario | Time Required | Skill Level |
|---|---|---|
| Water line already stubbed out | 2–4 hours | Intermediate DIY |
| Running new line (accessible wall) | 6–8 hours | Advanced DIY/Pro |
| Running new line (closed wall, tile backsplash) | 8–12 hours | Professional recommended |
| New construction (pre-drywall) | 1–2 hours (rough-in) + 1 hour (finish) | Plumber |
What Is a Pot Filler?
A pot filler is a wall-mounted faucet positioned above the stove that swings out on an articulated arm to fill pots directly on the burner. It connects to the cold water supply only and eliminates the need to carry heavy pots of water from the sink to the stove.
Step-by-Step Installation Process
Phase 1: Planning and Prep (30–60 Minutes)
Determine the mounting height, which is typically 18–24 inches above the stove surface or about 4 inches above the tallest pot you regularly use. Locate the nearest cold water supply line and plan your routing. Shut off the main water supply or the relevant branch valve.
Key considerations:
- Height: The faucet must clear the tallest pot on your largest burner
- Reach: The arm should extend to the center of the farthest burner
- Stud location: You need solid backing behind the wall for mounting
- Fire clearance: Maintain adequate distance from gas burner flames
Phase 2: Running the Water Line (0–6 Hours)
If a stub-out already exists, skip to Phase 3. Otherwise, this is the most time-consuming part of the project.
Accessible wall (open back or removable panel): Cut into the drywall behind the stove, tap into the nearest cold water line with a tee fitting, and run a new line (typically 1/2-inch copper or PEX) to the desired height. Install a drop-ear elbow or stub-out at the mounting point. Time: 3–5 hours.
Closed wall with tile backsplash: This is significantly more complex. You may need to remove tile, cut into drywall, run the line, patch the wall, and reinstall tile. Time: 5–8 hours. Professional installation is strongly recommended for this scenario.
Phase 3: Mounting the Faucet (1–2 Hours)
With a water line stubbed out and a mounting plate or backing installed, the faucet installation is straightforward:
- Thread the faucet onto the stub-out fitting, using thread tape or pipe dope
- Tighten the mounting hardware to secure the faucet to the wall
- Ensure the articulated arm swings freely and reaches the desired burners
- Check that the faucet sits level
Phase 4: Testing and Finishing (30–60 Minutes)
Turn the water back on slowly and check every connection for leaks. Test the faucet through several full open-and-close cycles. Check the joints where the arm articulates, as these are common leak points. Patch and paint any wall areas that were opened during installation.
Cost Considerations
Pot filler faucets range from $150–$500 for the fixture. Professional installation typically costs $300–$800 for labor, depending on whether new plumbing needs to be run. The total project cost including materials usually falls between $500–$1,500.
DIY vs. Professional Installation
If a water line is already stubbed out, a confident DIYer with basic plumbing experience can handle this project. The faucet connection is a standard threaded fitting, and the mounting is similar to any wall-mounted fixture.
However, running a new water line inside a finished wall is a different level of project. It requires cutting and patching drywall, soldering or crimping water line connections, and ensuring everything is watertight before closing up the wall. A licensed plumber can typically complete the entire project in half a day.
Common Pitfalls
- Forgetting a shut-off valve: Always install an accessible shut-off valve on the pot filler supply line for maintenance and emergencies.
- Wrong height: Measure carefully with your actual pots before committing to a height.
- Insufficient backing: The wall must have solid backing (blocking between studs) to support the weight of the faucet and the forces from swinging the arm.
The Bottom Line
If your kitchen already has a water line stubbed out behind the stove, installing a pot filler takes 2–4 hours. Running new plumbing adds 4–8 hours to the project. For closed walls or tile backsplashes, professional installation is the safer and often more cost-effective choice.
