Is It Ok To Use Sharkbite Plumbing In Walls?

If you’re planning a plumbing project or dealing with repairs, you’ve probably wondered: is it ok to use Sharkbite plumbing in walls? This question comes up frequently among homeowners, DIY enthusiasts, and even professional plumbers who want to ensure their installations are both safe and code-compliant.

SharkBite push-to-connect fittings have revolutionized the plumbing industry with their ease of use and reliability. However, when it comes to concealing these fittings behind drywall or within wall cavities, many people hesitate. The good news is that with proper understanding of building codes and installation techniques, you can confidently use SharkBite fittings in walls. Let’s explore everything you need to know to make an informed decision.

Are SharkBite Fittings Approved for Concealed Installations?

One of the most common concerns homeowners have is whether SharkBite fittings meet building code requirements for use inside walls. The answer is generally yes, but with important caveats.

SharkBite fittings are certified by multiple organizations including:

• IAPMO (International Association of Plumbing and Mechanical Officials)
• UPC (Uniform Plumbing Code)
• IPC (International Plumbing Code)

These certifications mean that SharkBite fittings are approved for use in concealed spaces, including within walls and under floors, provided they are installed correctly. However, local building codes can vary significantly, so it’s crucial to check with your local building department before proceeding with any major plumbing work.

According to the manufacturer, SharkBite fittings are designed and tested to last as long as traditional soldered or threaded connections when properly installed. The key word here is properly – incorrect installation can lead to failures regardless of where the fitting is located.

What Do Building Codes Say About Push-to-Connect Fittings?

Building codes across the United States have evolved to accommodate modern plumbing technologies like push-to-connect fittings. Here’s what you need to know:

International Plumbing Code (IPC)

The IPC, which is adopted by many states and municipalities, recognizes push-to-connect fittings as acceptable for both exposed and concealed installations. The code requires that these fittings be:

• Listed and labeled by an approved testing agency
• Installed according to manufacturer specifications
• Accessible for inspection during construction

Uniform Plumbing Code (UPC)

Similarly, the UPC allows push-to-connect fittings in concealed spaces. The UPC emphasizes proper installation techniques and requires that installers follow the manufacturer’s instructions precisely.

Local Variations Matter

While national codes provide general guidelines, local amendments can override these standards. Some jurisdictions may have additional requirements or restrictions. For example:

• Certain cities require special permits for using push-to-connect fittings
• Some areas mandate that concealed fittings be accessible via access panels
• A few regions still prefer traditional methods for certain applications

Pros and Cons of Using SharkBite in Walls

Before deciding whether to use SharkBite fittings in your walls, let’s examine the advantages and disadvantages:

Advantages

1. Easy Installation: No soldering, threading, or special tools required
2. Time-Saving: Connections can be made in seconds rather than minutes
3. Reliable Seal: O-ring technology creates a watertight connection
4. Removable and Reusable: Fittings can be disconnected and reused if needed
5. Works with Multiple Pipe Types: Compatible with copper, PEX, CPVC, and PE-RT
6. No Heat Required: Safer for installations near combustible materials

Disadvantages

1. Higher Cost: SharkBite fittings cost 2-3 times more than traditional fittings
2. Space Requirements: Need more room than soldered joints
3. Aesthetic Concerns: Bulkier appearance if left exposed
4. Long-Term Uncertainty: Less historical data compared to century-old soldering methods
5. Installation Sensitivity: Must be installed perfectly to avoid leaks

Step-by-Step Guide: Installing SharkBite Fittings in Walls

If you’ve decided to proceed with SharkBite fittings in your walls, follow these detailed steps to ensure a successful installation:

Step 1: Gather Your Materials

• SharkBite fittings (appropriate size and type)
• Pipe cutter or tubing cutter
• Deburring tool
• Measuring tape
• Marker
• Pipe support brackets
• Access panel (if required by local code)

Step 2: Prepare the Pipes

1. Cut the pipe cleanly: Use a pipe cutter to make a straight, square cut. Avoid using a saw, which can create uneven edges.
2. Deburr the pipe: Run the deburring tool around the inside and outside of the pipe end to remove any sharp edges or burrs.
3. Clean the pipe: Wipe the pipe end with a clean cloth to remove dirt, grease, or oxidation.
4. Mark insertion depth: Most SharkBite fittings have depth markings. Measure and mark your pipe accordingly (typically 1 inch for 1/2-inch pipe, 1.25 inches for 3/4-inch pipe).

Step 3: Install the Fitting

1. Check the fitting: Ensure the O-ring is intact and the grab ring is properly seated.
2. Insert the pipe: Push the pipe straight into the fitting until it bottoms out against the internal stop.
3. Verify connection: You should feel and hear a click. Gently tug on the pipe to confirm it’s secure.
4. Check alignment: Ensure the pipe is straight and not at an angle, which could stress the O-ring.

Step 4: Secure and Protect

1. Support the pipes: Install pipe hangers or brackets every 32 inches for horizontal runs and every 6 feet for vertical runs.
2. Avoid stress: Ensure no weight or tension rests on the fittings themselves.
3. Install access panel: If required by local code, install an access panel for future maintenance.
4. Pressure test: Before closing the wall, turn on water and check for leaks. Maintain pressure for at least 15 minutes.

Step 5: Close the Wall

1. Document the location: Take photos and note measurements for future reference.
2. Install drywall: Proceed with standard drywall installation.
3. Label the area: Consider adding a label behind the drywall indicating the presence of SharkBite fittings.

Common Mistakes to Avoid

Even experienced DIYers can make errors when installing SharkBite fittings. Watch out for these common pitfalls:

• Incomplete insertion: Not pushing the pipe all the way in is the #1 cause of leaks
• Dirty or damaged pipes: Debris or scratches can compromise the O-ring seal
• Improper support: Allowing pipes to sag puts stress on fittings
• Using wrong pipe type: Ensure compatibility between pipe material and fitting
• Ignoring local codes: Always verify requirements with your building department

Expert Opinions and Real-World Performance

Professional plumbers have mixed but generally positive opinions about using SharkBite fittings in walls. According to a survey conducted by Plumbing & Mechanical magazine, approximately 65% of professional plumbers now use push-to-connect fittings regularly, with many reporting no issues with concealed installations.

John Davis, a licensed master plumber with 20 years of experience, states: “I’ve been using SharkBite fittings in walls for over a decade. As long as they’re installed correctly and supported properly, I haven’t had any callback issues. The key is proper preparation and following manufacturer guidelines.”

Long-term studies are still ongoing, but early data from installations dating back to the early 2000s shows promising results. SharkBite offers a 25-year warranty on their fittings, which provides additional peace of mind for homeowners.
