Plastic push-fit plumbing fittings myths

With the rise of plastic push-fit plumbing fittings, many myths have surfaced over the years about their quality and performance. In this blog post, discover the truth behind common misconceptions about plumbing devices, revealing why blind belief isn't always accurate.

Four myths you shouldn’t believe about plastic push-fit plumbing fittings

We all know the benefits of push-fit fittings: they’re quick and easy to install and don’t require any tools to assemble. However, some industry professionals are still unsure about using them and believe they remove the skill from the trade. We’ve set out to challenge these myths and prove that push-fits are a great option for installers.

Myth 1: Soldering pipes is a true skill and using push-fits devalues the trade

Although simple to install, the technology behind the push-fit system is actually extremely innovative. Their ability to twist & lock® into position and provide high-pressure performance makes them an invaluable piece of technology for installers to have in their armour.

Push-fit systems can also be much more practical than soldering in certain scenarios. To give an example, renovating older buildings often involves dealing with existing plumbing infrastructure located within walls, floors, or tight spaces. Traditional soldering requires access to the pipes, which can lead to extensive demolition or removal of walls and floors to reach the soldering points. On the other hand, push-fit plumbing systems provide a convenient solution. The push-fit fittings can be easily inserted into the existing pipes without the need for extensive access or disruptive demolition. In addition, many renovation projects involve unforeseen changes or modifications to the plumbing layout. Push-fit plumbing systems offer greater flexibility in adapting to these changes given that the fittings can be easily disconnected and reused, allowing for adjustments without the need to replace or discard materials.

There’s no denying that soldering is a skill that installers can and should take pride in, but push-fit fittings also hold an important role in today’s evolving industry.

Myth 2: Plastic push-fit fittings are only compatible with plastic pipes

Not at all. Push-fit fittings are designed to lock any two pipes together and the material of the two pipes doesn’t even have to be the same, so it’s also compatible with a variety of different materials including copper, PEX, PVC, and CPVC as well as plastic. The ability of push-fit fittings to accommodate different pipe materials is particularly advantageous in situations where existing plumbing systems have a mix of pipe types. It allows for seamless integration and simplifies repairs or renovations without the need for extensive pipe replacements or conversions.

Myth 3: Plastic doesn’t last

This is only the case for poor-quality devices. Products that have been approved by the British Standards Institute, the British Board of Agrément, or the Water Regulations Advisory Scheme (WRAS) will have a high level of quality and durability. By checking if all components are manufactured in the UK, which is the case for the JG Speedfit push-fit fittings, you can be sure that the product has been rigorously tested to meet high British and international standards. Plastic push-fit fittings, when properly installed and used according to manufacturer guidelines, exhibit excellent durability. They are engineered to withstand high-pressure conditions and resist corrosion, making them suitable for various plumbing applications. The materials used in their construction are specifically chosen for their durability and longevity, ensuring they can endure the demands of everyday use in plumbing systems.

Myth 4: Where’s the skill involved?

Using push-fit fittings doesn’t remove the skill of being a plumber at all, which has many other job requirements that shouldn’t be underestimated or forgotten. In fact, arguably the most important skill for a professional plumber to have is the ability to use the most suitable system for the application. Plumbing professionals play a vital role in system design, customisation, problem-solving, and ensuring compliance with regulations. The integration of push-fit fittings into their work allows them to enhance their efficiency and offer improved solutions to clients, ultimately elevating the value of their profession. So, by using a push-fit fitting, you’re not losing a skill, just utilising another. 

And the art of plumbing remains intact?

It does indeed. As with any industry, new technology and changes always come along, and while it’s good to do your research, you shouldn’t ignore pioneering products that could add real value to the customer and your bottom line. By understanding the facts and debunking myths, we can make informed decisions and fully appreciate the value that push-fit plumbing fittings bring to the industry.
