Why Plumbers Are Wary of Sharkbite Fittings

If you have a house, you’ve probably heard about SharkBite fittings in plumbing. 

SharkBite fittings are plumbing components designed for making quick and reliable connections in water supply lines without the need for soldering, gluing, or specialized tools. They are widely used in plumbing projects, especially by DIY enthusiasts, for their ease of installation and versatility. 

While these fittings claim to be quick and easy for fixes, but they’ve caused some plumbers to have doubts. Let’s dive into plumbing and find out why some plumbers are skeptical about SharkBite fittings.


One major gripe among plumbers is durability. You see, traditional methods like soldering create a rock-solid connection that can withstand the test of time. But Sharkbite fittings? Well, they’re a bit like the fast food of plumbing – quick and convenient, but not necessarily built to last. Over time, these fittings can succumb to wear and tear, leading to leaks that can turn your cozy home into a soggy mess.


Another bone of contention is cost. While Sharkbite fittings might seem like a cheaper solution upfront, they can end up costing you more in the long run. Plumbers argue that investing in quality materials and workmanship pays off down the road, while quick fixes can lead to recurring issues that drain your wallet faster than a leaky faucet.


Now, let’s talk about safety. Plumbers are all about ensuring your home’s plumbing is tip-top and secure. Sharkbite fittings, while convenient, can sometimes fail to provide that peace of mind. When it comes to crucial applications like gas lines or high-pressure systems, plumbers are hesitant to trust these fittings to hold up under pressure. Nobody wants a plumbing mishap that turns your house into a water park or worse.


Speaking of convenience, there’s no denying that Sharkbite fittings are super easy to install. Just push ’em on, and you’re good to go, right? Well, here’s the thing – this simplicity can lead to amateur mistakes. Novice DIYers might not fully understand the ins and outs of proper plumbing, leading to improper installations and potential disasters down the line.

While Sharkbite fittings may seem like a plumber’s arch-nemesis, they do have their time and place. For small, temporary fixes or non-critical applications, they can be a quick and convenient option. But for the big leagues of plumbing, where durability, cost-effectiveness, and safety are paramount, many plumbers prefer to stick with traditional methods.

FAQs About Sharkbite Fittings

Are Sharkbite fittings safe for all plumbing applications?

While Sharkbite fittings are convenient for many plumbing situations, they may not be suitable for all applications. They are generally considered safe for common household plumbing, such as connecting water lines for sinks, toilets, and showers. However, for critical systems like gas lines or high-pressure plumbing, it’s advisable to consult with a professional plumber to determine the appropriate fittings and materials for safety reasons.

Can I use Sharkbite fittings for outdoor plumbing projects?

Sharkbite fittings are designed for indoor use and should not be exposed to direct sunlight or harsh outdoor conditions. For outdoor plumbing projects, consider using materials and fittings specifically rated for exterior use to prevent deterioration and ensure long-term durability.

Are Sharkbite fittings a suitable choice for DIY plumbing projects?

Sharkbite fittings are often chosen for DIY plumbing projects due to their ease of use. They can be a good option for minor repairs or installations, such as fixing a leak under a sink or replacing a shut-off valve. However, for more complex plumbing tasks or critical systems, it’s wise to consult a professional plumber. DIYers should have a basic understanding of plumbing principles and always follow the manufacturer’s guidelines for Sharkbite fittings to ensure a secure and leak-free connection.

Other Types of Plumbing Fittings

Let’s explore some lesser-known but equally essential plumbing fittings that can play a crucial role in your home’s waterworks. From barbed fittings to push-fit connectors, these alternatives come with their own unique features and benefits, making them worth considering for specific plumbing applications.

  1. Soldered Copper Fittings:


  • Durability: Soldered copper fittings are known for their long-lasting durability. When properly installed, they can withstand high pressure and are resistant to corrosion.
  • Watertight Seal: Soldered connections create a watertight seal, reducing the risk of leaks.
  • Heat Resistance: Copper can handle high temperatures, making it suitable for both hot and cold water applications.
  • Proven Track Record: Copper plumbing has been used for decades, and its reliability is well-established.
  • Soldering or using a propress system is the standard for copper water lines and should be used for longevity.  
  • When it comes to choosing between Propress and solder, there is no one-size-fits-all answer. It really depends on your specific needs and preferences.  Propress is a great option for those who want a quick installation process with less risk of leaks.


  • Skill Required: Soldering copper fittings requires a level of skill and experience, making it less DIY-friendly for beginners.
  • Labor-Intensive: The installation process can be labor-intensive and time-consuming, especially for larger projects.
  • Cost: Copper fittings and piping can be more expensive compared to some other materials.
  1. PEX Fittings (Cross-linked Polyethylene):


  • Flexibility: PEX is highly flexible, allowing for easier installation around obstacles and in tight spaces.
  • Corrosion Resistance: PEX is resistant to corrosion and scale buildup, improving its longevity.
  • Quick Installation: PEX fittings often use push-to-connect or crimping methods, making them more DIY-friendly and quicker to install.
  • Cost-Effective: PEX is generally more affordable than copper, both in terms of material and labor costs.


  • Not Ideal for High Temperatures: PEX is not recommended for very hot water applications, such as direct sunlight exposure or very high-temperature water heaters.
  • Not Suitable for Outdoor Use: PEX should not be used for outdoor plumbing or exposed to UV rays.
  • Fittings May Be More Expensive: While PEX tubing is cost-effective, some specialized PEX fittings can be more expensive.
  1. Compression Fittings:


  • Versatility: Compression fittings can be used with various materials, including copper, PEX, and even plastic.
  • No Heat Required: Unlike soldering, compression fittings don’t require heat, making them a good choice for DIY projects.
  • Reusable: They are reusable, allowing for adjustments or repairs without needing new fittings.


  • More Bulk: Compression fittings tend to be bulkier compared to soldered or PEX fittings, which can make them less suitable for tight spaces.
  • Cost: High-quality compression fittings can be expensive compared to other types.
  • Potential for Leaks: If not installed properly, compression fittings can develop leaks over time.

Adhering to local plumbing codes and regulations is paramount when making any changes to your plumbing system. These guidelines are not just bureaucratic red tape; they exist to ensure safety and compliance with established standards. By following them diligently, homeowners can avoid potential legal troubles and, more importantly, safeguard the well-being of their households.

DIY or Professional Job?

DIY plumbing repairs or installations can be a cost-effective and rewarding option for homeowners in certain scenarios. Tasks like fixing minor leaks, replacing faucet washers, or installing a new showerhead are usually manageable for those with basic plumbing skills.

However, it’s crucial to recognize one’s limitations; tackling complex plumbing issues, such as sewer line repairs, gas line work, or extensive pipe replacements, without the necessary expertise can lead to costly mistakes and even safety hazards.

Opt for Skills and Expertise

When it comes to more intricate plumbing projects or situations where safety and precision are paramount, it’s best to call in the experts – professional plumbers. They bring years of experience, the right tools, and an in-depth understanding of local codes and regulations to the table. Whether it’s diagnosing hidden leaks, ensuring proper drainage, or addressing major plumbing emergencies, hiring a skilled plumber can save you time, money, and headaches in the long run. 

Remember, the key to a successful plumbing endeavor is knowing when to roll up your sleeves and when to tap into the expertise of those who do it for a living.

The choice of plumbing fittings depends on various factors, including the specific plumbing needs, budget, and level of expertise. Soldered copper fittings are robust and durable but require skill. PEX fittings are flexible and cost-effective but have limitations in high-temperature applications. Compression fittings offer versatility but may be bulkier and more costly. Homeowners should consider these factors carefully and consult with a professional plumber if they’re unsure about the best option for their plumbing projects.
