The Future of Plumbing: Why Commercial Contractors Are Shifting to Copper Press and PEX Piping Systems

The plumbing industry is undergoing a major transition. In commercial buildings, copper pipes have traditionally been soldered with a torch for decades. Soldered connections are effective, but the process is labor-intensive, time-consuming, and requires highly trained personnel and strict safety measures on the job site. Commercial contractors are increasingly turning to Copper Press and PEX piping systems as they become faster, safer, and more efficient. These technologies eliminate most restrictions of conventional soldering, boost productivity, reduce labor, and keep installation quality consistent for contractors. This transition is a key moment for plumbing wholesalers to understand for inventory management and sustained growth. As workers seek greater efficiency in their installations and code-compliant performance, demand for wholesale PEX crimping tools, copper press systems, and special connection equipment has increased.

What is Driving the Change Away from Torch Soldering?

Although traditional copper soldering is a well-known and reliable method, it poses problems for many commercial projects.

These challenges include:

• Increased labor requirements
• Longer installation times
• Fire-watch and work permit requirements
  
• Reduced production in occupied buildings
• Higher project risk due to open flames

With a labor shortage in the construction sector, contractors are looking for connection methods that make installation easy and dependable. Copper Press and PEX systems overcome these issues by making mechanical connections without heat.

What are Copper Press Systems?

Copper Press systems employ special press fittings and a specialized press tool, which is manual or hydraulic, such as the 1632HY Hydraulic Copper Tubing Press Tool, or battery-operated, to establish a permanent pipe connection. The press tool presses the fitting onto the pipe instead of soldering, which forms a mechanical seal.

Benefits include:

• Faster installation speeds
• Reduced labor requirements
• Removal of open flame hazards
• Consistent connection quality
• Improved job-site safety

Copper Press systems have proven to be a very appealing choice for commercial plumbing fitting installation in hospitals, schools, office buildings, hotels, and retrofit applications where minimizing disruption is critical.

What Are PEX Crimp and Clamp Systems?

Cross-linked polyethylene (PEX) piping systems are becoming more popular for commercial and residential plumbing because they are flexible, durable, and easy to install. PEX systems are usually connected through mechanical crimping using tools such as the ICP-PK01 KIT PEX Crimping Tool or clamp connections using tools such as the PC-CRP1096 PEX Clamp Tool.

Advantages include:

• Flexible pipe routing
• Reduced fitting requirements
• Reduced installation labor expenses
• Corrosion resistance
• Faster project completion

As PEX installations grow, so does demand for professional, dedicated, reliable, code-compliant PEX crimping tools for the wholesale market.

Standard Compliance Criteria for Commercial Contractor Validation

Installation speed is crucial, but commercial contractors also need to meet industry plumbing codes and performance standards. Two of the most common standards that are cited in PEX installations are ASTM F1807 and ASTM F2098.

So, What is ASTM F1807 Compliance?

ASTM F1807 is a specification for Plumbing Systems using PEX piping and includes requirements for metal insert fittings and copper crimp rings.

The criteria included in the standard are related to:

• Dimensional tolerances
  
• Material requirements
  
• Joint integrity
• Long-term durability

Contractors and inspectors often use ASTM F1807 compliance for plumbing as an indicator of system reliability.

What Is ASTM F2098?

ASTM F2098 specifies the properties of stainless-steel clamp systems for the joining of PEX tubing.

Requirements include the following:

• Clamp performance
• Connection security
• Material specifications
• Installation consistency

Together, ASTM F1807 and ASTM F2098 ensure PEX systems achieve long-term performance in commercial operating environments.
