Push fit pipe fittings are a type of plumbing fitting that is designed to connect pipes without the need for welding, soldering, or threading. They are quick and easy to install, making them a popular choice for DIY enthusiasts and professional plumbers alike. In this article, we will explore what push fit pipe fittings are, how they work, their advantages and disadvantages, and the different types of push fit pipe fittings available.
What are push fit pipe fittings?
Push fit pipe fittings are plumbing components that allow for the easy and secure connection of pipes without the use of traditional pipe joining techniques such as soldering, welding or threading. Push fit fittings are often made of brass, copper, PVC, or plastic materials and are designed to work with a range of pipe materials and sizes.
How do push fit pipe fittings work?
Push fit pipe fittings work by using a mechanical seal to secure the connection between two pipes. The fittings are designed with a collar that slides over the end of the pipe, which is then pushed into the fitting. Inside the fitting, there is a rubber or silicone O ring that creates a seal between the pipe and the fitting.
When the pipe is pushed into the fitting, the collar slides over the O ring and locks it in place, creating a secure and watertight seal. The O ring also acts as a cushion, reducing the risk of pipe damage and ensuring a reliable connection that can withstand pressure and temperature changes.
Advantages of push fit pipe fittings
There are several advantages to using push fit pipe fittings, including :
Ease of installation : Push fit fittings are quick and easy to install, requiring no special tools or equipment. This makes them an ideal choice for DIY enthusiasts and professional plumbers who want to save time and money on installation costs.
No heat required : Push fit fittings require no heat to install, eliminating the risk of fire or injury from hot pipes.
Versatile : Push fit fittings can be used with a range of pipe materials and sizes, making them a flexible and versatile option for a wide range of plumbing applications.
No leaks : Push fit fittings provide a reliable and watertight seal, reducing the risk of leaks and water damage.
Reusable : Push fit fittings can be easily removed and reused, making them a sustainable and cost effective option.
Disadvantages of push fit pipe fittings
While push fit pipe fittings offer many advantages, there are also some disadvantages to consider :
Cost : Push fit fittings can be more expensive than traditional pipe joining techniques, although they may be more cost effective in the long run due to their ease of installation and reusability.
Limited temperature and pressure range : Push fit fittings may not be suitable for high temperature or high pressure applications, as the O ring seal may fail under extreme conditions.
Not suitable for all pipe materials : Push fit fittings may not work with all types of pipe materials, so it is important to check compatibility before using them.
Types of push fit pipe fittings
There are several types of push fit pipe fittings available, including :
Couplings : Couplings are used to connect two pipes of the same size and material. They are available in various sizes and materials, including brass, copper, PVC, and plastic.
Elbows : Elbows are used to change the direction of a pipe by 90 degrees. They are available in various sizes and materials and can be used with different pipe materials.
Tees : Tees are used to connect three pipes of the same size and material. They are available in various sizes and materials and can be used with different pipe materials.
Reducers : Reducers are used to connect pipes of different sizes. They are available in various sizes and materials and can be used with different pipe materials.
Adapters : Adapters are used to connect pipes of different materials or sizes. They are available in various sizes and materials and can be used to connect PVC pipes to copper, brass or plastic pipes.
Stop ends : Stop ends are used to close off the end of a pipe. They are available in various sizes and materials and can be used to cap off pipes that are no longer in use or to temporarily stop the flow of water.
Valves : Valves are used to control the flow of water through pipes. They are available in various sizes and materials and can be used to turn water on or off or to regulate the flow of water.
Push fit fittings for gas : Push fit fittings can also be used for gas plumbing, but the fittings used for gas installations are specially designed and tested to withstand the higher pressures involved.
How to install push fit pipe fittings
Installing push fit pipe fittings is a simple process that can be completed in a few easy steps :
Cut the pipe to the required length using a pipe cutter or saw.
Ensure that the end of the pipe is clean and free from burrs or debris.
Slide the push fit fitting over the end of the pipe, making sure that the O ring is in place.
Push the pipe into the fitting until it clicks into place.
Check that the pipe is securely connected by pulling on it gently.
If necessary, use a pipe insert to provide additional support and prevent the pipe from collapsing.
It is important to follow the manufacturer's instructions when installing push fit pipe fittings to ensure a secure and reliable connection.
In conclusion, push fit pipe fittings are a convenient and easy to install option for connecting pipes in a range of plumbing applications. They offer many advantages, including ease of installation, versatility, and reliability. However, it is important to consider their limitations and compatibility with different pipe materials and applications. By following the manufacturer's instructions and ensuring that the fittings are installed correctly, push fit pipe fittings can provide a secure and long lasting connection that is ideal for both DIY enthusiasts and professional plumbers.
