Welcome to another edition of our Hub Spotlight series where do a deep dive into the men and women who make the trades great. This spotlighted tradesperson tells us that he really enjoys trashy reality TV. “Nothing like kicking your feet up and watching someone making horrible life decisions on 90-Day Fiancé on a Sunday evening.” Joking aside, for Keith McGillivary (@mps_207)—full-time business owner of McGillivary’s Plumbing Services (MPS), Gardiner, Maine, for the past two years—his story into the plumbing trades is an interesting one.
McGilivary’s path started in a small town when a small plumbing business was looking for a helper, and he was looking for a job. “Little did I know it would be the start of where I am now,” says McGillivary. Before college, McGillivary started working for a small plumbing business that primarily focused on service work. The owner, Russell, was/is a great mentor and really took the time to help him understand not only what they were doing, but why they were doing it.
After deciding to pursue plumbing, McGillivary attended Southern Maine Community College (SMCC) for its plumbing and heating program. Through college, he continued to work alongside his mentor, and after graduation, continued to work for him full time for three years. McGillivary then took a job at Bath Iron Works (BIW) as a pipefitter building destroyers, ships for the United States Navy. “The piping systems were complex, and although it was “plumbing on a ship,” it was completely different. I found it fun to learn the ins and outs of that particular plumbing,” says McGillivary.
Eventually, McGillivary joined the Pipefitter Test Crew and tested the piping systems after they were built. He worked there for six years, but the whole time he continued to work nights and weekends doing plumbing work on the side. “This allowed me to gain hours and knowledge for my Master’s test. After passing my Masters, I decided to make the plunge into self-employment because I wanted the schedule flexibility for my family,” says McGillivary.
In fact, McGillivary’s biggest motivation for self-employment was time, rather than money. “I have learned to set firm boundaries for myself when scheduling and taking on jobs. I have been able to take more time off for my family than ever. Being a service plumber, in this day in age, you could work 24/7 if you wanted. I try to work ‘normal’ hours, and if I can take a day off for family stuff, I always do,” says McGillivary.
Shout Out to Mentorship
According to McGillivary, Russell taught him everything he knows about plumbing and owning a business. “He taught me all the hands-on work, how to write estimates & bid on jobs, customer relations, and how to balance a small business/family life,” says McGillivary.
And McGillivary wants to pay it forward. “I definitely consider myself a role model for others looking to join the trade. I feel I am a good example that hard work and dedication pays off,” says McGillivary. “My mentor was so important to my journey that I try to give back what I can by being transparent about my plumbing knowledge.”
Uplifting the Trades
Recently, there has been a big push for kids to attend trade school so there has been a shift in younger people showing interest, says McGillivary. “Trade school was beneficial for me to learn the code side of things, in an environment different from the hands-on work. I think we could get more interest in the trades if the schools showcased all the different avenues someone could go once they completed their schooling, and the financial opportunities that come with them. Everyone expects a doctor to make six figures, but not everyone knows you can make that in the trades without massive student loan debt,” says McGillivary.
“Everyone expects a doctor to make six figures, but not everyone knows you can make that in the trades without massive student loan debt.”
Social media can also be used to attract more people to the trades. “I see it all too often when guys in the trade are way too harsh on people for asking questions on Facebook plumbing pages. There are so many people asking questions for the purpose of learning and gaining knowledge. We were all there at some point, so be kind enough to answer the questions in a helpful manner. Social media can also be used to form “new-to-the-trades” communities and to provide seminars,” says McGillivary.
Social media also has played a huge role in the growth of McGillivary’s business. Starting as a small, part-time business with the help of word-of-mouth recommendations on small town Facebook pages, which made McGillivary realize that social media could be used to showcase the work he is doing on a day-to-day basis. “I use my Instagram to show what I am about as a business and the work I put out. I have found that if a customer can see why you are more expensive than the other guy, then they are more likely to go with you. I use it as an open-door insight to my business both in reels and daily stories,” says McGillivary.
McGillivary uses social media to learn little tricks of the trade that he just wouldn’t have been exposed to, being from such a small town. For McGillivary, it is extremely beneficial to be able to have conversations with such great tradesmen. He also talks to apprentices daily or weekly about projects, and gives them advice. “I wish when I was learning, I had this platform to learn and meet others. As visual learners, much like a lot of trades guys I know, it’s changed the way we can learn,” says McGillivary.
Making Time
Summers in Maine are short, so McGillivary tries to spend every nice weekend camping in his camper. In the winter months you can find him on his snowmobile at camp. “I would love to ride my snowmobile from camp in northern Maine to the Gaspe Peninsula to complete the “Great Gaspe Snowmobile Tour,” a six-day, 1,500-mile ride around some of the best trails,” says McGillivary.
And the last day McGillivary said it was a great day? “You know it’s funny, as I look back on just yesterday—camping with my family, beautiful weather, everyone smiling, does it get much better than that? So, the answer to that question would be yesterday!”
Go-To Tools on the Job
According to McGillivary, his go-tools are a couple pairs of Knipex Cobra pump pliers, a 6-in-1 screwdriver, and an adjustable wrench. Any good service plumber can fix most things with those!
Also, I find myself feeling naked if I don’t have my Leatherman Wave on me. Another great tool that has many uses.
Lastly, if there was one tool that changed the service plumbing game, it’s the M12 Milwaukee press tool. If you’re running a service company and don’t have one, you’re late to the party.

When a century-old Dallas railroad company headquarters required major renovations to transform into a Homewood Suites by Hilton, initial cost estimates for the hydronic heating system came in too high.
That’s when City Wide Mechanical of Dallas looked to alternative piping systems for a solution. They found PEX-a pipe with F1960 expansion connections to be the ideal system, due to its durability and ease of installation in addition to the job-site productivity, safety and, best of all, profitability potential it provided.
And City Wide Mechanical isn’t alone in their findings. Many mechanical contractors are discovering the benefits of PEX-a pipe and F1960 connections as the preferred alternative to copper, iron, and steel, which have dominated the mechanical piping industry for decades.
Benefits of PEX-a
PEX is an acronym for crosslinked polyethylene. It has been used in North America since the mid-1980s, starting with radiant floor heating systems, then moving into plumbing and, eventually, to hydronic hot-water heating and chilled-water applications.
PEX can be manufactured via three different processes, which create products with varying crosslinking percentages that allow for different characteristics. PEX-a is the most durable, flexible, and resilient with crosslinking around 85%. PEX-b is a stiffer piping product with crosslinking around 65% to 70%, and PEX-c features crosslinking around 70% to 75%.

One major benefit of the higher crosslinking in PEX-a is its extreme flexibility along with its thermal and shape memory. The flexibility of PEX-a eliminates most connections in smaller-diameter piping, saving time and money with up to half the connections required in rigid metal piping systems. To make a change in direction, the installer simply bends the pipe instead of having to stop and make a fitting. There are also bend supports available that help hold a bend securely in place.
The thermal memory of PEX-a provides kink repairability with a simple shot of heat from a heat gun. This eliminates the need to add in a coupling if a kink ever occurs in the pipe. (It is important to note that kink repairability is not possible with PEX-b or PEX-c pipe.)
The shape memory of PEX-a allows the pipe to expand and contract back down to its original shape. This makes it extremely resilient in freezing conditions and also provides for the fastest, easiest, most reliable PEX-a fitting system — F1960 expansions.
Expansion fittings require one simple tool to expand the pipe and an expansion ring before inserting a fitting. As the pipe and expansion ring naturally shrink back to their original shape, it creates a strong, durable connection that holds tight and can never be dry-fit. (Note: It is not recommended to expand PEX-b or PEX-c pipe due to microcracking that can occur.)
The innovative expansion fitting method eliminates torches, glues, and solder from a job site for greater worker safety. Plus, the system is extremely easy for installers to learn, helping get new crews up to speed quickly.
Speaking of job-site safety, PEX is also much lighter in weight compared with metal systems. For example, a 300-foot coil of 1/2-inch PEX weighs about 18 pounds, whereas the same amount of copper pipe weighs around 85 pounds. The lighter weight of PEX makes it safer and easier for installers to move around a job site and also eliminates the need for heavy-lifting equipment.
PEX-a also has a long-term advantage over copper when it comes to performance longevity. It is a static system, meaning its internal surfaces — which are three times smoother than copper — will not pit, scale, or corrode. That means its performance will remain the same from day one through decades of use.
Finally, because it is not a traded commodity, PEX-a holds a relatively stable material cost. This makes bidding a project much more consistent and reliable.
Application Details and Installation Tips
PEX-a is regulated by the ASTM F876 standard, which denotes temperature and pressure ratings of 200°F at 80 psi (pounds per square inch), 180°F at 100 psi, and 73.4°F at 160 psi. These values are well within the range of operation for most hydronic systems, including chilled beams, fan coil units, baseboards, radiators, hydronic VAV (variable-air volume) reheat coils, and radiant manifolds.
Because PEX is oxygen-permeable, it is important to use a pipe with an oxygen barrier that limits oxygen diffusion to levels below DIN 4726. This will protect the metallic components in the mechanical piping system, such as valves, strainers, and pump volutes, from corrosion.
The pipe is manufactured in sizes from 5/16 inch up to 4 inches and features a copper tube size (CTS) outside diameter. This means all the off-the-shelf components used in a copper hydronic piping system — hangers, supports, and insulation — can be the same.
For horizontal piping, the industry offers PEX-a Pipe Support — a galvanized-steel channel that is 9 feet in length and available in PEX pipe sizes from ½ inch to 3½ inches. This solution enables hanger spacing similar to copper pipe and helps control the natural expansion and contraction of the pipe as it heats and cools.
Because PEX-a expands at 1.1 inches per 100 feet per 10°F Delta T (which is 10 times that of copper), installing anchors every 65 feet and using PEX-a Pipe Supports allows PEX-a to function much like a copper system. In fact, different installation methods have a different effect on the overall net expansion rate.
With a strut-and-clamp system, using PEX-a Pipe Supports and anchoring with fixed points reduces the expansion rate of PEX-a to 0.08 inches per 100 feet per 10°F Delta T (a rate less than copper). And a loop-and-clevis system can reduce the rate to 0.12 inches per 100 feet per 10°F Delta T.

“Any day building custom mechanical rooms is a great day,” says Tyler Dynes (@dyneshvac), lead installer—with a specialty in hydronics—for Farr Mechanical Corp., greater Toronto area. You see, for Dynes, the most rewarding part of his work is seeing the finished install and hearing the customer say, “this is the nicest room in the house.”
In fact, Dynes loves what he does so much, one of his bucket list items is building his own home with a custom hydronic system.
Dynes’ rise into the trades started right out of high school where he began a career in automotive mechanics. After a few years in the field, he soon realized it just wasn’t for him. After speaking to someone at a local fuel/HVAC company, Dynes decided to give working for them a try. Several of his friends were in the industry already and encouraged him to enter the trade. “I worked with that company for about 11 years, learning everything I could in the residential HVAC field. It was here I became a gas fitter, oil burner and started my AC apprenticeship,” says Dynes.
Tyler with Brandon Farr (l), owner of Farr Mechanical.
One of my Dynes’ first mentors was a seasoned tech named Chris who Dynes trained under for five years at that first HVAC company. I also follow the careers of Eric Aune (@mechanicalhub), Mike Flynn (@flynnstone1), Don Taylor (@dontaylor53) and Aaron Bond (@bond_aaron) closely on Instagram. “They inspire me to push myself and learn more about all the different aspects of the trade. I still look up to them and chat with them from time to time,” says Dynes.
Dynes hadn’t considered himself a role model, just someone who takes a lot of pride in what he does. “I hope that I can encourage people to join the trade, and for those already in it, to push themselves to learn new skills. I would love for people to look at my work and be able to ask questions to help them learn everything I have and beyond,” says Dynes.
And with that, social media has allowed Dynes to grow professionally and personally as he loves the relationships that he’s built through it. Dynes is amazed at the support and encouragement he’s received over the last few years through his Instagram posts and stories. “It has such a great community of people from all trades supporting each other,” says Dynes.
Yet social media can become addicting, says Dynes, and it can be hard to step away. “After I get home, there are usually questions or conversations that happen through Instagram about my posted installs or other people looking for advice. I try to help when I can, but I know it’s important to put my phone down and spend time with my family, which can be going to the cottage with his family and riding his dirt bike,” says Dynes.
Over the past decade, there is no debating social media has become a place where contractors can show off their work and wares, and connect. This should help enhance the trades. “We need to showcase the fun side of trades and that no day is ever the same. There are so many areas that you can excel or specialize in, and we need to make that more known to people. It’s a hard work, fast-paced environment, but it’s so rewarding when you get the freedom to be creative,” says Dynes.

Rehau, Germany—REHAU says it has seen the development of the crisis and the suffering of the people in Ukraine with shock and great concern. Here is a statement from the company:
As a company that operates in Ukraine, as well as in Russia and Belarus, we emphasize our position:
- We strongly condemn the attack on Ukraine and its people.
- It is a war against humanity, the freedom of all of us and peace in Europe.
- And thus against the values for which we as a REHAU Group stand with all our subgroups.
We have decided to suspend our operations in Russia and Belarus until further notice.
Russia in particular, where we have been present for many years, is an important market for us. We hope that the situation will soon change in such a way that we can resume our activities in both countries.
Our priority now is the safety of our colleagues and their families in Ukraine and those that are leaving the country. We began preparing possible contingency plans some time ago. Concrete help is underway at various levels:
- Via the emergency aid fund “Family for Families,” which has been endowed by the company with a significant sum to provide immediate assistance, but also to support reconstruction later on.
- Via the crisis taskforce, which coordinates support for our team in Ukraine, but also for the people fleeing. We are in constant contact with the local management for this.
- And via an account we have set up for donations from our 20,000 employees worldwide.
We hope for a peaceful outcome and our thoughts remain with everyone affected by the conflict.
