Push pull dogs, also known as pipe dogs, are often mentioned in online forums and DIY blogs as tools for pipe fitting. However, this term often leads to confusion and misinformation. There is no actual tool called a “push pull dog” specifically designed for pipe fitting. The correct tools for joining pipes depend on the material and type of connection, such as PVC cement for plastic pipes, soldering for copper pipes, or threading and pipe wrenches for metal pipes. Let’s clarify the misconceptions surrounding “push pull dogs” and explore the proper tools and techniques for pipe fitting in the US.
Understanding the Confusion Around “Push Pull Dogs”
The term “push pull dogs” likely stems from a misunderstanding or miscommunication regarding tools used in other trades, perhaps involving pulling cables or other materials. It’s crucial to understand that using incorrect terminology can lead to improper tool selection and potentially dangerous situations when working with pipes.
Proper Tools for Pipe Fitting
For successful and safe pipe fitting, it’s essential to use the correct tools. Here’s a breakdown of common pipe fitting tools used in the US:
- Pipe Wrenches: These adjustable wrenches are essential for gripping and turning pipes and fittings. Different sizes are available for various pipe diameters.
- Pipe Cutters: Used for cleanly cutting pipes made of different materials like copper, PVC, or CPVC.
- Threading Tools: If working with threaded pipes, you’ll need tools like pipe threaders and dies to create or repair threads.
- Soldering Equipment: For copper pipes, a soldering iron, flux, and solder are necessary for creating leak-proof joints.
- PVC Cement and Primer: Used for joining PVC pipes, these create a strong and permanent bond.
Common Pipe Fitting Techniques
Different pipe materials and connection types require specific techniques. Here are some common methods used in the US:
- Solvent Welding (for PVC): This involves applying primer and cement to the pipe and fitting before joining them.
- Soldering (for Copper): Heating the joint and applying solder creates a strong, sealed connection.
- Threading (for Metal Pipes): Threading the pipe and fitting allows them to be screwed together.
- Compression Fittings: These use a compression ring and nut to create a seal.
- Push-Fit Fittings: These fittings allow for quick and easy connection without special tools, but are typically used for specific applications and may not be suitable for all types of plumbing.
Safety Precautions for Pipe Fitting
Safety should always be a priority when working with pipes. Here are some crucial safety tips:
- Eye Protection: Wear safety glasses to protect your eyes from debris and chemicals.
- Gloves: Protect your hands from sharp edges and chemicals by wearing appropriate gloves.
- Ventilation: Ensure adequate ventilation, especially when working with solvents or soldering.
- Proper Tool Usage: Use tools correctly and for their intended purpose.
- Turn Off Water Supply: Always turn off the water supply before working on any plumbing.
Conclusion
While the term “push pull dogs for pipe fitting” may be a misnomer, understanding the correct tools and techniques for pipe fitting is crucial. By using the appropriate tools and following safety guidelines, you can ensure successful and safe pipe fitting projects in your home or on the job. Remember to always consult local plumbing codes and regulations for specific requirements in your area.
