Key Highlights

  • Proper application and correct sizing are essential for effective boiler replacement, with installation quality being the top priority

  • Press tools allow plumbers to work in confined spaces safely, avoiding open flames and property damage associated with soldering or brazing

  • Modern press tools are versatile, capable of pressing copper, PEX, cast iron, and iron pipe fittings, streamlining multiple tasks with a single tool

  • Speed and safety are significantly improved with press technology, reducing job time and minimizing hazards on site

Eric Aune is a well-known figure in the plumbing-heating-cooling industry. As well as being a sometime-columnist for CONTRACTOR, he is the owner of Aune Plumbing & Heating, LLC, and host of the Make Trades Great Again podcast.

For this Q&A, Aune puts on his Master Plumber hat to discuss near-boiler piping issues, and how modern press tools can make the job faster and easier than ever.

 

CONTRACTOR: Given the efficiencies modern boilers can deliver, a lot of contractors are getting work doing boiler replacement work. What are some key considerations to keep in mind during a boiler replacement? 

Eric Aune: Proper application and appropriate sizing (for starters) are what I would consider most important when selecting a boiler for replacement. Ultimately the most important detail to consider is proper installation. 

Many installers only skim the install manual or never read it at all. After decades of service and repair work I see more improperly installed equipment than not. This is likely related to the rush to complete jobs faster than ever before, often by design, by which I mean from how the back office is  scheduling and overseeing the work.  

CONTRACTOR: Near-boiler piping on these jobs can be tricky. There are often space constraints, sometimes unusual hook-ups, sometimes it’s cost-prohibitive to demo and remove the old boiler and the new piping has to work around the old machine. Why are press tools the better way to tackle these problems? 

Aune: There never seems to be enough space to work comfortably, but pressing allows us to work in tighter spots without worry of open flames and possible property damage. Whether overhead, deep into a corner, or up against a wall, if you can fit the jaw or ring around the fitting all that’s left is to press the tool’s trigger. This is a sharp contrast by comparison when considering soldering or brazing copper pipe. 

CONTRACTOR: What are some of the features of modern press tools that let them deliver both versatility and performance? 

Aune: Today’s press tool is more multi-tool than one-trick pony. I’m regularly using my press tool to cut threaded rod for pipe hangers, or to snap cast iron soil pipe for a plumbing repair. In place of threading pipe, we are almost exclusively pressing iron pipe fittings on gas and hydronic piping systems. 

Early pressing was limited to the fittings available; today pressing seem only limited by the size of fittings, but not the catalog selection or fitting type. Just this week I used the same press tool to press copper (of course), PEX, and iron pipe all in the same day. It’s not only safer, faster and reliable but also versatile.
