Pros and Cons of Using Plastic Inserts for Push Fit Fittings
Push fit fittings have become increasingly popular in the plumbing industry due to their ease of installation and versatility. These fittings are designed to connect pipes without the need for soldering or glue, making them a convenient option for both DIY enthusiasts and professional plumbers. However, when it comes to push fit fittings, one common question that arises is whether or not plastic inserts are necessary for a secure connection.

Plastic inserts are small pieces of plastic that are placed inside the push fit fitting before inserting the pipe. These inserts are designed to provide additional support and stability to the connection, ensuring a leak-free seal. While some manufacturers recommend using plastic inserts for all push fit fittings, others claim that they are not necessary in certain applications.
One of the main advantages of using plastic inserts is that they help to prevent the pipe from collapsing or deforming when it is inserted into the fitting. This can be particularly important when working with soft or flexible pipes, as they may not have enough rigidity to maintain their shape on their own. By using plastic inserts, you can ensure that the pipe remains securely in place, reducing the risk of leaks or other issues down the line.
Additionally, plastic inserts can help to distribute the force of the connection more evenly, reducing the likelihood of damage to the pipe or fitting. This can be especially important in high-pressure applications, where a secure and reliable connection is essential. By using plastic inserts, you can help to extend the lifespan of your push fit fittings and ensure that they continue to perform effectively over time.

On the other hand, some argue that plastic inserts are not always necessary for push fit fittings. In certain applications, such as low-pressure systems or where the pipe is rigid and well-supported, plastic inserts may not provide any significant benefits. In these cases, using plastic inserts may be seen as an unnecessary extra step that adds to the overall cost and complexity of the installation.
Ultimately, the decision of whether or not to use plastic inserts for push fit fittings will depend on the specific requirements of your project. If you are working with soft or flexible pipes, or if you are dealing with high-pressure systems, using plastic inserts may be a wise choice to ensure a secure and reliable connection. However, if you are working with rigid pipes in a low-pressure system, you may be able to forgo the use of plastic inserts without compromising the integrity of the connection.
In conclusion, plastic inserts can be a valuable tool for ensuring a secure and leak-free connection when using push fit fittings. While they may not always be necessary, they can provide added support and stability in certain applications. By carefully considering the requirements of your project and weighing the pros and cons of using plastic inserts, you can make an informed decision that will help to ensure the success of your plumbing installation.
