Why Are Plumbers Against Sharkbite Fittings?

Imagine a quiet house, the only sound the gentle hum of pipes carrying water through the walls. Suddenly, a burst, and chaos ensues.

Plumbers often steer clear of Sharkbite fittings due to a range of concerns that go beyond mere convenience. From the reliability of connections to long-term durability, the issues surrounding these fittings are vast and impactful.

Let’s explore why these seemingly simple solutions are a point of contention in the plumbing world.

Lack of Reliability Concerns

When it comes to Sharkbite fittings, their lack of reliability has been a constant source of frustration for plumbers in the industry. Performance limitations are a significant concern with Sharkbite fittings. While they may work well for simple DIY projects or temporary solutions, their performance under high pressure or in critical applications is questionable. Plumbers often encounter leaks or failures with Sharkbite fittings in demanding conditions, leading to callbacks and dissatisfied customers.

Installation challenges further compound the issue. While Sharkbite fittings are marketed as easy-to-use solutions for quick repairs, the reality is that improper installation can lead to leaks or even bursts. The push-to-connect design, although convenient, requires meticulous attention to detail to ensure a proper seal. Many plumbers find that the time saved during initial installation is often lost when dealing with callbacks due to faulty fittings.

Long-Term Durability Questions

Long-term durability questions surrounding Sharkbite fittings persist among plumbers due to concerns over their performance and reliability in demanding conditions. When evaluating the longevity of these fittings, two critical factors come into play: material integrity and corrosion resistance.

  1. Material Integrity: One of the primary worries among plumbers is the long-term structural integrity of Sharkbite fittings. While they’re convenient for quick installations, questions arise regarding how well they’ll hold up over time, especially in high-stress environments where traditional soldered connections have historically been relied upon for their robustness.

  2. Corrosion Resistance: Another point of contention is the fittings’ ability to resist corrosion. In plumbing systems where exposure to moisture and various chemicals is common, the long-term performance of Sharkbite fittings under such conditions is a subject of debate.

  3. Reliability Under Pressure: Plumbers also question how well Sharkbite fittings will maintain their seal and performance over years of use, particularly in systems where pressure fluctuations are frequent. The ability of these fittings to withstand sustained pressure without deteriorating is a critical aspect that remains under scrutiny.

Compatibility and Code Compliance Issues

Questions surrounding the durability and performance of Sharkbite fittings extend to their compatibility with existing plumbing systems and adherence to plumbing codes. Material compatibility is a critical factor to consider when using Sharkbite fittings. While these fittings are designed to work with various types of pipes such as copper, PEX, and CPVC, compatibility issues may arise with certain types of older pipes or non-standard materials. This can lead to leaks or other plumbing failures if not addressed properly.

Installation challenges can also be a concern when using Sharkbite fittings. While they offer a convenient push-to-connect design, improper installation can result in leaks or even pipe bursts. It’s crucial to follow the manufacturer’s instructions carefully and ensure that the pipes are cut cleanly and inserted fully into the fitting to prevent any issues.

In terms of code compliance, some plumbers may have reservations about using Sharkbite fittings in certain applications. While these fittings may be approved for use in specific situations, there are instances where local plumbing codes may restrict their use. It’s essential to verify with local authorities and ensure that the fittings meet all relevant code requirements before installation.

Cost and Value Considerations

Considering the overall cost and value of Sharkbite fittings is essential when evaluating their suitability for plumbing projects. These fittings offer a balance between cost savings and installation ease, but there are important factors to consider:

  1. Cost Savings: While Sharkbite fittings may have a higher upfront cost compared to traditional fittings, they can lead to cost savings in the long run. The ease and speed of installation can result in reduced labor costs, making them a cost-effective option for certain projects.

  2. Installation Ease: One of the most significant advantages of Sharkbite fittings is their ease of installation. Without the need for soldering or specialized tools, they can significantly reduce the time required to complete a plumbing job. This ease of installation can also minimize the risk of errors, saving both time and money.

  3. Value Considerations: When weighing the cost of Sharkbite fittings against their ease of installation and potential long-term savings, it’s crucial to assess the overall value they provide for your specific plumbing project. While they can be a valuable asset for certain applications, it’s essential to consider your project’s requirements and budget constraints before making a decision.

Skill and Pride in Craftsmanship

Skill and pride in craftsmanship play vital roles in plumbing work, influencing the quality and longevity of installations. Traditionally, plumbers have honed their skills through years of apprenticeship and hands-on experience, valuing the precision and artistry involved in creating a well-executed plumbing system. The debate between tradition vs efficiency arises when considering modern innovations like Sharkbite fittings. While these fittings offer convenience and speed in installations, they can sometimes compromise the meticulous craftsmanship that plumbers take pride in.

Craftsmanship vs convenience is a dilemma that many plumbers face in today’s fast-paced world. On one hand, the ease of using Sharkbite fittings can save time and effort during installations. However, on the other hand, some argue that relying too heavily on these quick-fix solutions can diminish the level of skill and attention to detail that traditional plumbing techniques demand. Ultimately, finding a balance between embracing efficiency and upholding the standards of craftsmanship is key to ensuring the integrity and longevity of plumbing systems.


So, next time you think about using sharkbite fittings, just remember that plumbers have their reasons for being against them. It’s not just about being stubborn or old-fashioned. It’s about upholding standards, ensuring quality, and taking pride in their craftsmanship.

After all, would you trust a quick fix over a tried and true method? Plumbers certainly don’t. Stick to the traditional methods and leave the sharkbites for the sharks.
