Pressing vs. Soldering: Which Pipe Joining Method is Better?

The right kind of pipe joining method will ensure a leak-free connection so as to handle pressure well. Needless to say, this increases the longevity and effectiveness of the piping system. As plumbers and construction workers deal a lot with pipes in their day-to-day activities, it is essential that they choose the right pipe joining method.

The two most common pipe joining methods are pressing and soldering. These two differ in application and are the two most sought-after options by plumbers and construction workers. This blog evaluates which pipe is better in terms of effectiveness and reliability.

What Is Pipe Pressing?

Pipe pressing refers to a technology that joins two pipes by using a hydraulic pipe press tool. This paves the way for a leak-free connection and results in completing a project quickly. Copper and stainless steel pipes are mainly used in this method. 

The key advantages of pipe pressing are high efficiency, convenience, reliability, etc. However, there are limitations as well, which appear in the form of low flexibility and high initial investment, which is needed for pipe joining tool(s).

What Is Pipe Soldering?

Pipe soldering is the process of using a filler metal (solder) to join two metal surfaces. This is one of the effective ways to join copper pipes. If any plumber is looking for how to join copper pipes, soldering is the way to go. This method has been in use in different industries for decades. 

The main benefits of pipe soldering are its cost-effectiveness, leak-proof joints, and versatility. However, some of the common drawbacks are fire risk (open flame needed), time-consuming, and the need for extremely skilled professionals. 

Understanding the Key Distinctions between Pressing and Soldering 

Plumbers who are at a loss about which to choose between pressing and soldering for joining pipes can take a look at the table below! 

Table: The Key Differences between Pressing and Soldering 

Suitability in Different Scenarios 

To understand which is the better method between pressing and soldering, you need to understand how they apply to different projects. 

For Homeowners

Although it is not the job of a layman to join plumbing pipes, a basic understanding is still called for.

When to Consider Pressing? 

Pressing is a good choice if homeowners prefer a quicker installation. All they need is a suitable pipe joiner tool. This is also a safe process because of no fire hazard. This method is also devoid of heat. 

When to Consider Soldering? 

Pressing can be a time-saving option for homeowners, but soldering is more affordable. The dilemma between time and money can be eliminated if a homeowner opts for soldering, but only if they possess the necessary skills to handle the matter of soldering pipes well. 

For Professional Plumbers 

There might be a doubt between the two methods for the homeowners, but not for the professional plumbers or even construction workers. They usually prefer pressing over soldering. 

But why? As a matter of fact, around 2500 soldering-related injuries take place annually in the USA. This naturally denotes that pressing is a safer option, as there is no flame. It is not a wise option for a professional to consider soldering because there is an open flame, which is risky for the property.

Pressing over soldering is preferred because it is highly accurate and time-saving. Hence, professionals need not spend a lot of time on pipe fitting. This ensures that the plumbing or the construction work is completed within the proposed deadline. 

What Happens in the Case of Specialty Projects?

Professionals consider different aspects of specialty projects to choose the right kind of pipe joining method. 

When to Choose Pressing?

If a project possesses large-scale pipe installations, pressing is a better option. This must also be prioritized when a project owner does not have adequate labor. Moreover, pressing is a better fit when there is not enough time for joining plumbing pipes.

When to Choose Soldering?

Soldering gets a nod ahead of pressing when a project needs a permanent connection. For example, heritage buildings rely on this method. Additionally, choose soldering if you do not have a high budget for materials, as the fittings are not so costly. 

What Are the Key Expert Tips for Pressing and Soldering?

There are several considerations to take into account in matters of pressing and soldering. Let’s discuss some expert tips for both methods. 

Pressing

To execute pipe pressing, professional plumbers must consider certain factors. Let’s check out the probable tips. 

• Consider a deburring tool for burrs removal after the pipe has been cut to a definite length.
• Select a press tool that goes well with the pipe’s size and fitting.
• To ensure an effective seal, daily calibration of tools is important.
• The tool must be perpendicular to the pipe.
• After the completion of the tool cycle, ensure that the fitting does not have any visible gaps.

Soldering 

This traditional process is not so easy to carry out. Here are some of the tips for soldering copper pipes.

• Use a wire brush to clean the inner area of the fittings and the pipe ends to remove oxidation.
• Ensure that the pipes are completely dry before soldering.
• To prevent oxidation, apply a thin flux layer inside the fittings and to the pipes.
• Keep in mind that even heating is to be given so that a reliable connection is made.

Can Both Pressing and Soldering Be Used Together? 

Plumbers choose either pressing or soldering when joining plumbing pipes. Well, there are situations when you don’t have to choose one method, as they can be combined. 

Combining these two methods requires perfect consideration of integrity and safety. Let’s check out some possible scenarios where you can use both. 

• In an Existing Press-fit System: Suppose you are repairing anything in a system where pressing has been done already. Here, you can go for soldering in other parts. 
• Requiring a Particular Type of Fitting: There might be an instance where a pipe section contains a press-fit connection, but the needed transition fitting is unavailable in a press-fit design. In this case, you can opt for soldering it.

How to Make the Correct Choice?

Pressing and soldering have different use cases. There are several aspects that influence your choice. These include:

Size of the Project 

Project size can be a key determinant of pipe joining methods. Copper press fittings are effective in larger-scale projects due to a low level of complexity. Well, you can rely on soldering pipes in residential projects. 

Budget

Are you comfortable with bearing a high upfront cost? If not, you can go for soldering. This process is more economical than pressing.

Experience

If you do not have a trained team, it's better to select pressing. Definite skills are needed for pipe soldering.

Wrapping Up: Which One Is Better? 

Pressing is a quick and safe pipe fitting method, and it is applicable in large projects. Meanwhile, soldering is a slow process with the risk of fire hazard. So, it can be concluded that pressing is better than soldering because it is safer, and there is no need for specific skills. However, the pipe fitting method selection depends on budget, project scope, and available skillset.

Selecting the Correct Pipe Joining Method

Do you need to select a pipe fitting for your project? Are you confused about the most suitable method? Consider the project size before identifying the better one. Also, make sure to get the plumbing tools from a reliable supplier.

Frequently Asked Questions

1. Which Pipe Fitting Method is Better for Sewage?
