3 Tips to Speed Your Piping Installs

Share With:

Speed and accuracy are the name of the game when it comes to a successful piping installation and a thriving business. Whether you’re installing potable plumbing or hydronic piping, the faster and more precise the job, the more time and money you potentially have to work on other projects.

While there are hundreds of tips and tricks out there to make your installs faster, easier, and more effective, I’m going to concentrate on the following three methods almost any plumbing or mechanical contractor can use to bring greater productivity to projects.

Flexible PEX pipe with bend supports

If you’ve never heard of PEX, it’s an acronym for crosslinked polyethylene. It’s a flexible, durable plastic piping product that provides numerous benefits over rigid CPVC or metallic systems, including faster installs, zero corrosion, and freeze-damage resistance.

Many residential contractors are already using PEX (considering it’s the most installed piping system for new-home construction over copper and CPVC combined). However, PEX is still a relative newcomer in the commercial industry.

The biggest benefit of PEX is its flexibility, which allows you to simply bend the pipe with each change in direction. With a tight bend radius of six times the pipe’s diameter, you can practically make 90-degree bends without the need for a fitting.

For times when you do have a tight bend that needs to stay in a particular place, PEX manufacturers offer bend supports. For those of you that prefer to watch rather than read, here’s a video that explains bend supports in detail.

These helpful products are available for ⅜”, ½”, ⅝”, ¾”, or 1″ PEX pipe. They hold the bend in place at the proper angle and take a fraction of the time compared to making a 90-degree elbow.

Most contractors agree that using flexible PEX with bend supports can eliminate most fittings in smaller-diameter pipe sizes 1″ and down, saving up to half the install time of a rigid piping system.

Expansion tools

When it comes time to make a connection with PEX pipe, the professionals’ choice is PEX expansion. Note that expansion connections are only designed for PEX-a pipe. If you’re using PEX-b or PEX-c pipe, you’ll need to use a different fitting type as PEX-b and PEX-c pipes aren’t made to expand like PEX-a pipe, and they will experience microcracking during expansion.

Expansion connections require one simple tool that expands the pipe and an expansion ring before inserting a fitting. As the pipe and ring shrink back down around the fitting, it creates a solid, strong seal that can withstand up to 1,000 pounds of radial force. It’s quick and easy to do and simple to learn, so it’s highly beneficial with the skilled-labor shortage that’s challenging the trades. Here’s a quick, 20-second video on how to make a connection.

Now, to make installs even faster, expansion tools have advanced to make connections even quicker. For up to 1″ connections, the Milwaukee® M12 FUEL™ ProPEX® Expander with RAPID SEAL™ Heads is the fastest tool yet — with up to 65% faster sealing times compared to previous models.

For larger-diameter pipe connections, the new Milwaukee M18 FUEL™ ProPEX Expander with ONE-KEY™ is taking commercial installs to a new level by offering 3X faster 2″ connections. To watch how much faster, check out this video from Milwaukee Tool.


Finally, let’s talk about prefabrication. This is becoming a big trend for national residential builders or large commercial projects that have a lot of repeatability on the project. By prefabbing certain sections of a project, it can shave days, weeks, or even months off a timeline, depending on how big the project.

Prefabricating piping assemblies in a controlled factory environment not only adds more efficiencies, it also provides an additional benefit of greater accuracy. By doing a job repeatedly, it hones the skill and gives installers greater confidence in their work.

Plus, having rows and rows of prefabbed piping assemblies in a shop environment makes it a lot easier to perform quality checks. Instead of walking for miles on a job site, a supervisor can save significant time simply walking a shop floor.

And here’s another area where flexible, durable PEX provides additional benefits. Transporting prefabbed PEX piping assemblies is much easier than transporting rigid assemblies that can crack or break. Because PEX is super flexible, it can withstand the rigors of being transported to a job site without worry.

So, there you have it…just a few ideas to keep in mind the next time you have a project with a tight deadline, and you’re squeezed on time and skilled labor. Every little bit helps when it comes to adding productivity to projects. If you have other ideas, I’d love to hear them. Feel free to email me at kim.bliss@uponor.com.
