How to Plumb a Pot Filler

Installing a pot filler in your kitchen can greatly enhance its convenience and functionality. A pot filler is an additional faucet installed near the stove, specifically designed for filling pots directly where you cook. This innovation not only saves time during meal preparation but also eliminates the need to carry heavy pots of water from the sink to the stove, reducing the risk of spills and potential injury. Understanding how to plumb a pot filler can seem daunting, but it’s a manageable task with the right guidance.

How to Plumb a Pot Filler

This guide will walk you through the entire process, starting with planning and ensuring you have the necessary tools and materials. We will then move on to the installation steps, detailing how to mount the pot filler and connect it to your water supply. Finally, we’ll cover the necessary steps to ensure all connections are secure and functioning correctly.

Planning and Preparation

Location Selection

Choose a spot above the stove that is within reach and convenient for use. Typically, placing the pot filler 12-18 inches above the cooking surface is ideal. This height allows for easy access while providing ample space for various pot sizes. Ensure the location is not obstructed by cabinetry or other fixtures and allows for the smooth operation of the pot filler arm.

Check Plumbing Access

Before proceeding with the installation, verify that there is access to a cold water supply line behind the wall where the pot filler will be installed. Assess whether the existing plumbing can accommodate a new fixture without requiring extensive modifications. This step is crucial to avoid any unexpected complications during the installation process.

Tools and Materials Needed

  • Pot Filler Faucet The main fixture is to be installed.
  • Shut-off Valve: Prevents water flow during maintenance or repair.
  • Copper or PEX Pipe: Used to connect the pot filler to the water supply.
  • Pipe Fittings and Connectors: These are necessary for joining pipe sections.
  • Pipe Cutter: This is used to cut pipes to the required length.

With careful planning and proper preparation, you’ll set a solid foundation for installing your pot filler efficiently and effectively.

Turn Off the Water Supply

Before starting the installation, it’s crucial to turn off the water supply to prevent any accidents or leaks. Locate the main water shut-off valve for your home, which is usually found near your water meter or where the main water line enters the house. Turn this valve to the off position to stop the flow of water into your plumbing system. After shutting off the main supply, open the nearest faucet to the installation site, allowing any remaining water in the lines to drain out.

Before Starting 
The Installation

This will reduce the pressure in the pipes and minimize the risk of water leakage during the installation process. Ensuring that the water supply is fully turned off and the lines are drained will create a safer and more controlled environment for working with your plumbing.

Run the Water Line

Access the Wall Cavity

  1. Use a Stud Finder to Locate and Mark the Studs in the Wall Behind the Stove:
  • This ensures that you won’t hit any studs or structural elements that could complicate the installation when you cut into the drywall.
  1. Cut a Hole in the Drywall to Access the Plumbing Area Where the Water Line Will Be Installed:
  • Make sure the hole is large enough to work comfortably but as small as possible to maintain the wall’s integrity. A drywall saw or utility knife can be used to make precise cuts.

Install the Shut-Off Valve

  1. Identify the Nearest Cold Water Supply Line:
  • Trace existing plumbing lines in your kitchen to find the most accessible point to branch off a new water line.
  1. Cut Into the Existing Cold Water Line Using a Pipe Cutter:
  • Ensure that the cut is clean and straight to facilitate a secure connection with the new fittings.
  1. Install a T-fitting Onto the Cut Section of the Pipe to Branch Off a New Line:
  • Apply Teflon tape to the threads if necessary to ensure a leak-free connection. Tighten the T-fitting securely.
  1. Attach a Shut-off Valve to the New Branch Line:
  • This valve is crucial as it will allow you to control the water flow to the pot filler independently. Secure the valve firmly in place to ensure it can be easily operated.
Ensuring It Doesn't Move 
And is Positioned Correctly

Run the New Pipe

  1. Measure and Cut the Necessary Length of Pipe (Copper or PEX) to Reach From the Shut-off Valve to the Location of the Pot Filler:
  • Accurate measurement is important to avoid unnecessary joints, which could become potential leak points.
  1. If Using Copper Pipe, Clean and Solder the Connections:
  • Cleaning the pipe ends and fittings with a wire brush and applying flux will ensure a strong, leak-proof connection when soldered.
  1. If Using Pex, Use the Appropriate Connectors and Crimping Tool:
  • Follow the manufacturer’s instructions for cutting, fitting, and crimping PEX as improper connections can lead to leaks.
  1. Secure the Pipe Inside the Wall Cavity, Ensuring It is Well-supported and Positioned Where the Pot Filler Will Be Installed:
  • Use pipe straps or clamps to secure the pipe to the wall studs, ensuring it doesn’t move and is positioned correctly for the pot filler installation.

Drill Hole for Pot Filler

  1. Drill a Hole in the Wall at the Chosen Location for the Pot Filler Faucet:
  • The hole should be just large enough to allow the pipe to pass through and connect to the pot filler. Use a drill bit that’s appropriate for the size of the pipe being used.
  1. Pull the End of the Pipe Through the Hole, Ready for the Faucet Installation:
  • Ensure that the pipe is not kinked or stressed as you pull it through. It should be positioned neatly and prepared for the final connection to the pot filler faucet.

Running the water line correctly is crucial for a successful pot filler installation. By following these steps meticulously, you’ll ensure that your pot filler has a reliable water supply and is securely supported within the wall cavity. Once the pipe is in place, you’re ready to proceed with mounting the pot filler and making the final connections.
