What are the common questions about installing SharkBite fittings on PEX?
Do I need any special tools to install SharkBite fittings on PEX pipe?
No, you typically don't need any specialized or expensive tools to install SharkBite fittings on PEX pipe. The primary appeal of SharkBite fittings is their push-to-connect design, which allows for a simple and tool-free installation in most situations. However, a few basic tools can be helpful for ensuring a clean and reliable connection.
While the fittings themselves require no crimping tools, expansion tools, or specialized wrenches, proper preparation of the PEX pipe is crucial for a leak-free connection. The most important tool to have is a PEX pipe cutter. Using a dedicated PEX cutter, rather than a saw or utility knife, ensures a clean, square cut that is essential for the O-ring within the SharkBite fitting to properly seal against the pipe. If the cut is angled or uneven, the connection may leak. Additionally, a deburring tool or a utility knife can be used to remove any burrs or sharp edges from the cut end of the PEX pipe. Although not strictly required, removing burrs helps the pipe slide smoothly into the fitting and reduces the risk of damaging the O-ring. Finally, a depth gauge, sometimes included with SharkBite fittings or available separately, can be used to ensure the PEX pipe is inserted to the correct depth within the fitting. While you can often mark the pipe with a pen, the gauge provides a more precise and reliable method.How deep should I insert the PEX pipe into the SharkBite fitting?
You should insert the PEX pipe into the SharkBite fitting until you feel it bottom out, reaching the internal tube stop. This ensures a proper seal and prevents leaks. It's crucial to push firmly and steadily until you meet resistance; this indicates that the pipe has passed the O-ring and is securely seated.
Once you've cut the PEX pipe squarely, it's essential to properly deburr the end, both inside and out, using a deburring tool or utility knife. This removes any sharp edges or burrs that can damage the O-ring inside the SharkBite fitting as the pipe is inserted. Damaged O-rings can lead to leaks, so deburring is a critical step for a watertight connection. After deburring, visually inspect the end of the pipe to ensure it is smooth and free of debris. To confirm the pipe is fully inserted, SharkBite fittings have a visual indicator. Most fittings have a marked insertion depth line on the outside. Once the pipe is fully inserted, you should be able to see that line is at or slightly inside the fitting. If the line is visible beyond the edge of the fitting, the pipe isn't fully seated, and you'll need to remove it using a removal tool and re-insert it, making sure to apply firm and steady pressure. If the fitting lacks an indicator line, push firmly until you can no longer push it further. Remember, a properly installed SharkBite connection requires the pipe to be fully inserted to the internal stop for a leak-free seal.What happens if the PEX pipe is scratched or damaged before using a SharkBite?
If the PEX pipe is scratched or damaged before using a SharkBite fitting, the fitting may not seal properly, leading to leaks or even complete joint failure. Scratches or gouges can create pathways for water to escape, bypassing the internal O-ring designed to create a watertight seal.
Even small imperfections on the PEX pipe's outer surface can compromise the SharkBite connection. The fitting relies on a smooth, consistent surface for the O-ring to compress against and form a reliable seal. Scratches, nicks, or cuts disrupt this smooth surface, preventing the O-ring from creating a watertight barrier. The depth and severity of the damage will influence the likelihood of a leak. A superficial scratch might not be as problematic as a deep gouge, but any visible damage should be addressed before installation. It’s always best practice to carefully inspect the PEX pipe before attempting to install a SharkBite fitting. If you discover any scratches or damage, cut the damaged section of pipe and use a new, undamaged section. Ensuring the pipe is clean, round, and free of any imperfections is essential for a successful and leak-free SharkBite connection. Attempting to use damaged PEX with a SharkBite is a gamble that can result in costly water damage and repairs down the line.Can I reuse a SharkBite fitting after it's been installed?
While technically possible, it is generally **not recommended** to reuse a SharkBite fitting after it has been installed. Although the fitting can be removed using a disconnect clip, the internal components, specifically the O-ring and stainless steel teeth, can become worn or damaged during the initial installation and removal process. This can compromise the fitting's ability to create a reliable, leak-proof seal in a new application, potentially leading to future leaks and water damage.
Removing a SharkBite fitting requires a specific disconnect tool, and even with careful removal, the small barbs that grip the pipe can lose some of their effectiveness. More importantly, the O-ring, which is critical for creating a watertight seal, can become deformed or develop microscopic tears. These imperfections might not be visible to the naked eye but can significantly increase the risk of leaks. The cost of a new SharkBite fitting is relatively low compared to the potential cost of repairing water damage caused by a failed reused fitting.
Furthermore, manufacturers typically void the warranty on SharkBite fittings that have been previously installed. Therefore, for optimal reliability and to maintain warranty coverage, it's best practice to use new SharkBite fittings for each connection. Consider the minimal cost of a new fitting as insurance against future plumbing issues and costly repairs.
Is it necessary to deburr the PEX pipe before inserting it into a SharkBite?
Yes, it is absolutely necessary to deburr the PEX pipe before inserting it into a SharkBite fitting. While SharkBite fittings are designed for quick and easy installation, a clean, smooth pipe end is crucial for a proper, leak-free connection. Failure to deburr the pipe can damage the fitting's internal o-ring and grab ring, leading to potential leaks or even a complete failure of the connection.
Even though SharkBite fittings are push-to-connect and seem forgiving, the internal workings rely on a very tight seal. The grab ring, which is what secures the pipe within the fitting, and the o-ring, which creates the watertight seal, are sensitive to imperfections. Burrs or sharp edges on the PEX pipe can easily nick or tear the o-ring as the pipe is inserted. This damage compromises the seal, increasing the likelihood of leaks, especially under pressure. Deburring ensures that the pipe end is smooth and consistent. A proper deburring tool, or even a utility knife used carefully, will remove any raised edges or plastic shavings left from cutting the pipe. After deburring, visually inspect the pipe end to confirm it is free of any debris or imperfections before inserting it into the SharkBite fitting. Take the extra few seconds to properly deburr; it's a small effort that can prevent significant problems down the road and ensure a long-lasting, reliable plumbing connection.What is the best way to remove a SharkBite fitting from PEX pipe?
The best way to remove a SharkBite fitting from PEX pipe is to use a SharkBite disconnect clip or a SharkBite disconnect tong. These tools depress the release collar on the fitting, allowing you to pull the PEX pipe free without damaging either the pipe or the fitting (if you intend to reuse it).
The SharkBite disconnect clip is a small, horseshoe-shaped plastic tool that slides around the pipe and pushes evenly on the release collar. You simply push the clip against the collar, ensuring it's fully engaged, and then gently pull the pipe out of the fitting. Disconnect tongs operate on the same principle but are larger and often easier to grip, especially in tight spaces or when dealing with larger diameter pipe. They essentially squeeze the release collar, freeing the pipe. Attempting to remove a SharkBite fitting without the proper tool can damage the internal components of the fitting, rendering it unusable. Furthermore, forcing the pipe can also score or damage the PEX, creating a potential leak point if you reconnect the same pipe. The disconnect tools are inexpensive and readily available at most hardware stores, making them an essential part of any plumbing toolkit when working with SharkBite fittings.Are SharkBite fittings compatible with all types and brands of PEX tubing?
While SharkBite fittings are designed to be universally compatible with PEX tubing meeting ASTM F876 standards, compatibility isn't guaranteed across *all* brands and types without careful consideration. Always verify that the PEX tubing you intend to use meets the required standards and has the correct outside diameter for the SharkBite fitting. Some non-standard or off-brand PEX tubing might not adhere strictly to these specifications, potentially leading to leaks or fitting failures.
SharkBite fittings are engineered to work seamlessly with PEX-A, PEX-B, and PEX-C tubing that conforms to the ASTM F876 standard, which specifies the dimensional and performance requirements for PEX tubing. It's critical to ensure that your PEX tubing has the correct outside diameter as indicated on the SharkBite packaging or product specifications. Slight variations in diameter, especially with non-certified or imported PEX, can compromise the fitting's seal. While SharkBite offers a degree of tolerance, significant deviations can lead to problems. Before undertaking any plumbing project, it's best practice to consult the SharkBite manufacturer's website or product documentation for a current list of approved PEX tubing brands and specifications. Performing a test connection on a scrap piece of your chosen PEX tubing is always recommended before installing the fitting in a permanent location. This simple check helps confirm a proper seal and ensures the fitting functions as intended with your specific type of PEX.And that's all there is to it!
