How to Mount a Water Spigot on a Concrete Wall with Surface PEX

When working with outdoor plumbing, mounting a water spigot to a concrete wall can quickly become a challenge—especially when your PEX line runs along the surface of the wall instead of through it. This situation creates two main issues: how to securely mount the spigot to the concrete and how to allow enough space for the PEX line to connect neatly.

I ran into this exact problem during a recent project, and after some trial and error, I came up with a DIY solution that worked beautifully. Using 1″x1″ aluminum square tubing (available at Lowe’s) and 90-degree elbow connectors, I built a small mounting frame that solved both issues. To securely attach the spigot, I used an XFITTING 1/2″ PEX x 3/4″ GHTsillcock, which is specifically designed for PEX connections. Finally, I fastened the frame to the wall with self-drillingTEK screws for a solid and weatherproof hold.

This sturdy yet lightweight frame provided the clearance I needed for the PEX line while creating a secure attachment point for the spigot. If you’re dealing with the same problem, this step-by-step guide will show you how to create a durable and professional-looking setup that’s easy to replicate and built to last.

Why Mounting a Spigot to Concrete Can Be Tricky

Mounting a water spigot to a concrete wall presents unique challenges that many DIYers encounter. Unlike wood or siding, concrete is dense and unforgiving, making it difficult to drill into and secure fixtures properly. Add a surface-mounted PEX line to the equation, and the problem becomes even more complicated.

Here’s why this setup can be tricky:

  • Concrete Requires Specialized Tools
    Drilling into concrete requires the use of a hammer drill and masonry drill bits, which can be intimidating if you’ve never worked with them before. Without the right tools, getting a secure mount isn’t possible.
  • PEX Lines Need Clearance
    Unlike traditional setups where water lines run through walls, surface-mounted PEX lines require space to connect cleanly to the back of the spigot. If the spigot is mounted flush to the wall, it leaves no room for the PEX connection, which can result in bending or kinking the line.
  • Durability and Stability Are Key
    Since outdoor spigots endure regular use and are exposed to weather, they need to be mounted in a way that ensures they won’t loosen or shift over time. This is especially true for concrete walls, where improper installation can lead to cracks or instability.

To make matters worse, ignoring these challenges can lead to long-term problems. For example, an unstable spigot setup can result in leaks, kinks in the PEX line, or even freezing in colder climates.

How to Build the Aluminum Frame for the Spigot

The key to mounting a water spigot securely to a concrete wall while accommodating a surface-mounted PEX line lies in the aluminum frame. This frame creates the clearance needed for the PEX line connection while ensuring the spigot is stable and firmly mounted. Here’s how to build it:

Step 1: Cut the Aluminum Tubing

  • Measure and cut two pieces of 1″x1″ aluminum square tubing to about 8 inches each. These will serve as the vertical supports for the frame.
  • Cut another two pieces for the horizontal sections that connect the supports. Adjust the length based on how much clearance you need for the PEX line to connect to the back of the spigot.

Step 2: Drill Holes for Wall Mounting

  • Take one of the vertical tubing pieces and mark spots for drilling mounting holes. These holes will allow you to attach the frame to the concrete wall.
  • Using a drill with a masonry bit, carefully create the holes. Ensure the spacing matches the positions where you’ll drill into the wall.

Step 3: Assemble the Frame with 90-Degree Elbow Connectors

  • Use 90-degree elbow connectors to join the vertical and horizontal tubing pieces into a rectangular frame.
  • Secure the connectors using small screws, ensuring a snug fit. These connectors will give the frame its durability and shape.

Step 4: Test the Fit and Adjust as Needed

  • Before mounting the frame to the wall, check that the spigot and PEX line will fit comfortably within the space. Adjust the frame size if necessary.

Why the Aluminum Frame Works So Well

This frame acts as an anchor point for your spigot while providing the extra space needed for the PEX line. Unlike mounting directly to the wall, the frame extends outward slightly, preventing any bending or kinking in the PEX line.

Once the frame is ready, it’s time to move on to securing it to the concrete wall. But before you do, make sure you’ve double-checked the measurements and alignment to avoid drilling errors.

Attaching the Frame to the Concrete Wall

Once your aluminum frame is built, the next step is mounting it securely to the concrete wall. This is a critical part of the project, as the frame must be stable enough to support the spigot and handle regular use. Here’s how to do it:

Step 1: Mark the Drill Points

  • Hold the assembled aluminum frame up to the wall in the desired location.
  • Use a marker to mark the spots where the mounting holes in the frame align with the wall. Double-check that the frame is level and positioned correctly.

Step 2: Drill Pilot Holes in the Concrete

  • Using a hammer drill fitted with a masonry bit, carefully drill into the marked points on the concrete wall.
  • Make sure the pilot holes are deep enough to accommodate the screws, but not so deep that they compromise the integrity of the wall.

Step 3: Attach the Frame to the Wall

  • Align the frame’s mounting holes with the pilot holes you drilled in the wall.
  • Secure the frame using self-drilling TEK screws. These screws are designed to penetrate both metal and concrete, ensuring a strong, weather-resistant hold. Tighten the screws firmly, but avoid overtightening to prevent damage to the aluminum tubing.

Step 4: Test the Stability

  • Once the frame is attached, test its stability by giving it a gentle shake. It should feel solid and not move or wiggle. If it does, double-check the screws and tighten them further if necessary.

Additional Tip for Long-Term Durability

To protect the drilled holes in the concrete and prevent water from seeping in, apply a small bead of silicone caulk around the edges of the screws. This will help seal out moisture and reduce the risk of cracks forming over time.

With the frame securely mounted to the wall, you now have a sturdy and reliable base for your spigot. Next, we’ll walk through how to connect the PEX line and attach the spigot to the frame. For more helpful DIY tips, check out heating it up: selecting and troubleshooting your ideal water heater.

Step 1: Drill a Hole in the Aluminum Frame

  • Identify the best spot on the aluminum frame for routing the PEX line.
  • Use a drill to create a hole large enough for the PEX line to pass through easily. The hole should be positioned so that the PEX can connect directly to the back of the spigot without bending or kinking.

Step 2: Feed the PEX Line Through the Frame

  • Push the PEX line through the drilled hole in the frame. Make sure there’s enough slack to comfortably connect it to the spigot.

Step 3: Attach the PEX Line to the Spigot

  • Connect the PEX line to the back of the spigot using an XFITTING 1/2″ PEX x 3/4″ GHT sillcock. This brass fitting is specifically designed to work with PEX tubing, ensuring a secure and watertight connection.
  • Use a crimp ring and crimping tool to secure the PEX line to the spigot. Make sure the connection is tight and free of leaks.

Step 4: Push the PEX Line Back Into the Frame

  • Once the PEX is connected to the spigot, gently push the remaining tubing back into the aluminum frame. This keeps the line protected and gives your setup a clean, professional look.

Step 5: Test for Leaks

  • Before proceeding, turn the water on and check for any leaks at the PEX connection. If you notice a leak, tighten the crimp ring or check the fitting to ensure it’s secure.

Why Protecting the PEX Line Matters

By routing the PEX line through the aluminum frame, you shield it from potential damage caused by weather, impact, or UV exposure. This step not only makes your installation look polished but also ensures long-term durability.

Now that the PEX line is connected and the frame is complete, it’s time to mount the spigot to the frame and finalize your setup. For more ideas on protecting outdoor plumbing and avoiding common DIY pitfalls, check out From Liquid to Blockage: The Hidden Dangers of Pouring Grease Down the Drain.
