Soldering vs ProPress - Pros and Cons

Installing piping systems has always been an integral part of new construction and renovation. Traditionally, soldering is used to join piping systems. While this process enables connections to be made, what many contractors don’t realize is that there are more efficient and reliable techniques available, and that leads us to an innovative pipe joining system that combines high quality and speed for a variety of materials. When soldering pipe connections, a number of elements can introduce poor bonds. Joints may be subjected to movement during the solidification process, fail to completely melt, or overheat. Any one of these missteps can create the potential for cracks and leaks in piping systems.

With the help of the new ProPress system, these uncertainties can be eliminated. Contractors can easily identify unpressed connections, allowing them to complete projects with confidence and avoid costly repairs. What also separates ProPress from soldering is its degree of versatility. Connections can be made in wet or dry conditions, helping contractors stay on schedule and streamline maintenance. The flameless press technology also eliminates the need for burn permits or fire watches that can stall productivity and introduce safety concerns.

The difference between Pros and Cons between Soldering and ProPress

Soldering a copper pipe can be done through two different methods, known as sweat fitting and brazing. Both of these have advantages and disadvantages, and if you are looking to join pieces of copper pipe together you may be unsure what is the best way of managing your piping. By examining the pros and cons of each method you can decide which one you would prefer to use in your project.

Sweat Soldering

Sweat fitting involves placing short pieces of pipe over the ends of the copper pipes you want to join together. The fittings are then heated, known as sweating until all of the parts are fitted together. This is a common method of joining ends of copper piping together, but as heat can quickly be moved away from the join through conduction, it often takes a lot of effort to warm the pieces enough to get a good solder joint, while keeping it cool enough to prevent oxidization of the metal. It is this fine balance between heat and cold that makes sweat soldering such a difficult method.


Brazing involves placing a metal in between the two joints to be fixed. Brazing often requires extremely high temperatures, and this can be a problem with copper pipes, since oxidation can take place rapidly. Brazing makes the joints stronger if done well, but they require a great deal of cleaning beforehand, which can make the task very time-consuming.

What Is ProPress?

ProPress is a system for connecting copper pipes. A plumber uses a ProPress to fit a pipe joint and itself is a trading name used by Manufacturer Viega, but there are also other companies manufacturing the ProPress type fittings. ProPress fittings have O-ring inserts at the ends of the fittings that will be tightened securely to the pipe when it is pressed on by the ProPress tool.


1. The number one advantage to ProPress is that there is no danger of starting a fire.

2. A plumber can save lots of time pressing fittings as opposed to sweating them.

3. A quick roughing of the pipe surface, sliding the fitting onto the pipe, putting the Propress in place, and then pulling the trigger, and you’re done.

4. Prepping and connecting the joint can be done in less than thirty seconds.

5. Corrosion-resistant does not need protective paint.

6. Durable, it does not deteriorate or become fragile.

7. Fully eco-friendly system.

8. More than 30 years of proven operation in the world.

9. Also, the plumber is able to make up joints when the water hasn’t been shut down entirely for whatever reason.


1. The number one Con of ProPress is the expense.

2. Basic ProPress machines will cost upwards of one thousand dollars, and bigger or more advanced units will cost much more.

3. The fittings are much more expensive than comparable sweat fittings.
