20 Biggest Plumbing Supply Companies in the World

In this piece, we will take a look at the 20 biggest plumbing supply companies in the world. For more companies, head on over to 5 Biggest Plumbing Supply Companies in the World.

While not as glitzy or glamorous as high technology, the plumbing industry is still one of the most important ones out there. The ability of humans to live and grow in large cities is dependent on modern day necessities such as plumbing, which includes services like hot water and waste disposal. Broadly speaking, there are six kinds of plumbing, including water supply, sanitary, gas fitting, drainage, roofing, and other services. And while modern day plumbing quietly chugs away at the bottom of cities and megastructures, systems such as sewage drainage have been around for thousands of years.

The Plumbing Industry: An Analysis

The growth in human population and the corresponding rise in living standards has also transformed the plumbing industry into quite a lucrative sector. For instance, a research report from Allied Markets Research believes that the plumbing components industry was worth $58.5 billion in 2019, and from then until 2027, it will grow at a compounded annual growth rate (CAGR) of 5.6% to sit at an estimated $78 billion by the end of the forecast period. The research firm divides the industry across both product categories and end use. For the former, the sector is segmented along fittings, manifolds, pipes, and valves. Out of these, pipes is the largest segment, accounting for a higher share than the other three categories combined. However, the fittings segment is expected to outpace the industry in terms of overall growth, through an estimated CAGR of 7.5%. The low share, high growth rate mix is also mirrored in products end use since while residential demand holds the higher market share, the nonresidential segment is expected to have the highest growth.

As is the case with nearly every other sector, the plumbing industry is also witnessing the growing adaptability of technology. These include interesting new devices such as water leak detection devices and brain pipes. The former is part of a group of gadgets called the Internet of Things (IoT) and they include leak detectors that connect to the home WiFi network and are also capable of detecting moisture and humidity levels. These devices also feature automatic water shut-off features that aim at preventing water loss and drainage in case of a leak. The latter arguably sound more interesting, since they are called ‘brain pipes’. These are part of a system that monitors all the pipes in a house and then monitors water usage for off nominal events such as a leak. If the system detects any such occurrence, it notifies the user and then shuts off the water supply to prevent potential damage and water loss.

These days, all that anyone can talk about (or worry about) is recession. Last year’s global energy and commodity price shocks coupled with rising inflation and high interest rates have created concerns for an economic downturn necessary to bring down prices and to ensure that elevated inflation does not become permanent. Well, according to the private equity industry, this might not be the case for the plumbing industry since investments in the sector grew significantly even during the peak of the coronavirus pandemic when most cities and counties were in lockdown. This stability for the sector even during an economic downturn is aided by the fact that home repairs continue even when business is down, particularly since plumbing is an essential service. Another reason plumbing tends to stay resilient in a volatile economy is that it is easier to scale the business up or down by adding or removing variable capacity markers such as vans or employees. Other businesses, such as large scale manufacturing operations, do not have such flexibility.

Looking at the broader macroeconomic outlook, the U.S. economy is refusing to slow down despite the Fed’s best efforts. This is partly due to large homeowner savings, which is enabling them to maintain buying behavior. These were also on the mind of Lowe’s Companies, Inc. (NYSE:LOW) chief executive officer Mr. Marvin Ellison, who shared during the firm’s Q4 2022 earnings call that:

From our perspective the core drivers of our business, disposable personal income, home price appreciation, and the age of housing stock, remain supportive. Consumer savings are still roughly $1.5 trillion higher than pre-pandemic, with 85% concentrated in the top 40% of income owners who are more likely to be homeowners. Homeowners continue to enjoy record levels of equity in their homes, nearly $330,000 on average.

Even if there is a modest decline in home prices, the level of equity built up during the pandemic would not be meaningfully eroded. And the housing stock continues to age with 50% of US homes over 41 years old, the oldest since World War II. These factors, along with strong millennial household formation, baby boomers’ increasing preference to age in place, and more widespread remote work will continue to be tailwinds for our business. And given the slowdown in housing turnover is driven by higher rates and low supply rather than demand, we continue to see a nationwide trend of trading up in place with consumers opting to upgrade their existing home to meet their evolving needs. All of these dynamics give us confidence in the medium and longer term outlook for the industry.

Today, we’ll look at some of the largest plumbing supply companies in the world, with the largest being Compagnie de Saint-Gobain S.A. (OTCMKTS:CODYY), CRH plc (NYSE:CRH), and Lowe’s Companies, Inc. (NYSE:LOW).

The $250 Trillion AI Hype is Real. A few years from now, you’ll probably wish you’d bought this stock.

Published on October 6, 2025 at by Inan Dogan, PhD

When Jeff Bezos said that one breakthrough technology would shape Amazon’s destiny, even Wall Street’s biggest analysts were caught off guard.

Fast forward a year and Amazon’s new CEO Andy Jassy described generative AI as a “once-in-a-lifetime” technology that is already being used across Amazon to reinvent customer experiences.

At the 8th Future Investment Initiative conference, Elon Musk predicted that by 2040 there would be at least 10 billion humanoid robots, with each priced between $20,000 and $25,000.

Do the math. According to Musk, this technology could be worth $250 trillion by 2040.

Put another way, that’s roughly equal to:

175 Teslas
107 Amazons
140 Metas
84 Googles
65 Microsofts
And 55 Nvidias

And here’s the wild part — this $250 trillion wave isn’t tied to one company, but to an entire ecosystem of AI innovators set to reshape the global economy.

It’s a leap so massive, it could reshape how businesses, governments, and consumers operate worldwide.

Even if that $250 trillion figure sounds ambitious, major firms like PwC and McKinsey still see AI unlocking multi-trillion-dollar potential.

How could anything be worth that much?

The answer lies in a breakthrough so powerful it’s redefining how humanity works, learns, and creates.

And this breakthrough has already set off a frenzy among hedge funds and Wall Street’s top investors.

What most investors don’t realize is that one under-owned company holds the key to this $250 trillion revolution.

In fact, Verge argues this company’s supercheap AI technology should concern rivals.

Before I reveal the details, let’s talk about how some of the richest people on the planet are positioning themselves.

Bill Gates sees artificial intelligence as the “biggest technological advance in my lifetime,” more transformative than the internet or personal computer, capable of improving healthcare, education, and addressing climate change.
Larry Ellison — through Oracle, is spending billions on Nvidia chips and partnering with Cohere to embed generative AI across Oracle’s cloud and apps.
Warren Buffett — not known for tech hype — says this breakthrough could have a ‘hugely beneficial social impact.

When billionaires from Silicon Valley to Wall Street line up behind the same idea — you know it’s worth paying attention to.

Even as we admire what Tesla, Nvidia, Alphabet, and Microsoft have built, we believe an even greater opportunity lies elsewhere…

But the real story isn’t Nvidia — it’s a much smaller company quietly improving the critical technology that makes this entire revolution possible.

And judging by what I’m hearing from both Silicon Valley insiders and Wall Street veterans…

This prediction might not be bold at all:

A few years from now, you’ll wish you’d owned this stock.

The best part? You can discover everything about this company and its groundbreaking technology right now.

AI, Tariffs, Nuclear Power: One Undervalued Stock Connects ALL the Dots (Before It Explodes!)

Published on October 5, 2025 at by Inan Dogan, PhD

Artificial intelligence is the greatest investment opportunity of our lifetime. The time to invest in groundbreaking AI is now, and this stock is a steal!

AI is eating the world—and the machines behind it are ravenous.

Each ChatGPT query, each model update, each robotic breakthrough consumes massive amounts of energy. In fact, AI is already pushing global power grids to the brink.

Wall Street is pouring hundreds of billions into artificial intelligence—training smarter chatbots, automating industries, and building the digital future. But there’s one urgent question few are asking:

Where will all of that energy come from?

AI is the most electricity-hungry technology ever invented. Each data center powering large language models like ChatGPT consumes as much energy as a small city. And it’s about to get worse.

Even Sam Altman, the founder of OpenAI, issued a stark warning:

“The future of AI depends on an energy breakthrough.”

Elon Musk was even more blunt:

“AI will run out of electricity by next year.”

As the world chases faster, smarter machines, a hidden crisis is emerging behind the scenes. Power grids are strained. Electricity prices are rising. Utilities are scrambling to expand capacity.

And that’s where the real opportunity lies…

One little-known company—almost entirely overlooked by most AI investors—could be the ultimate backdoor play. It’s not a chipmaker. It’s not a cloud platform. But it might be the most important AI stock in the US owns critical energy infrastructure assets positioned to feed the coming AI energy spike.

As demand from AI data centers explodes, this company is gearing up to profit from the most valuable commodity in the digital age: electricity.

The “Toll Booth” Operator of the AI Energy Boom

It owns critical nuclear energy infrastructure assets, positioning it at the heart of America’s next-generation power strategy.
It’s one of the only global companies capable of executing large-scale, complex EPC (engineering, procurement, and construction) projects across oil, gas, renewable fuels, and industrial infrastructure.
It plays a pivotal role in U.S. LNG exportation—a sector about to explode under President Trump’s renewed “America First” energy doctrine.

Trump has made it clear: Europe and U.S. allies must buy American LNG.

And our company sits in the toll booth—collecting fees on every drop exported.

But that’s not all…

As Trump’s proposed tariffs push American manufacturers to bring their operations back home, this company will be first in line to rebuild, retrofit, and reengineer those facilities.

AI. Energy. Tariffs. Onshoring. This One Company Ties It All Together.

While the world is distracted by flashy AI tickers, a few smart investors are quietly scooping up shares of the one company powering it all from behind the scenes.

AI needs energy. Energy needs infrastructure.

And infrastructure needs a builder with experience, scale, and execution.

This company has its finger in every pie—and Wall Street is just starting to notice.

Wall Street is noticing this company also because it is quietly riding all of these tailwinds—without the sky-high valuation.

While most energy and utility firms are buried under mountains of debt and coughing up hefty interest payments just to appease bondholders…

This company is completely debt-free.

In fact, it’s sitting on a war chest of cash—equal to nearly one-third of its entire market cap.

It also owns a huge equity stake in another red-hot AI play, giving investors indirect exposure to multiple AI growth engines without paying a premium.

And here’s what the smart money has started whispering…

The Hedge Fund Secret That’s Starting to Leak Out

This stock is so off-the-radar, so absurdly undervalued, that some of the most secretive hedge fund managers in the world have begun pitching it at closed-door investment summits.

They’re sharing it quietly, away from the cameras, to rooms full of ultra-wealthy clients.

Why? Because excluding cash and investments, this company is trading at less than 7 times earnings.

And that’s for a business tied to:

The AI infrastructure supercycle
The onshoring boom driven by Trump-era tariffs
A surge in U.S. LNG exports
And a unique footprint in nuclear energy—the future of clean, reliable power

You simply won’t find another AI and energy stock this cheap… with this much upside.

This isn’t a hype stock. It’s not riding on hope.

It’s delivering real cash flows, owns critical infrastructure, and holds stakes in other major growth stories.

This is your chance to get in before the rockets take off!

Disruption is the New Name of the Game: Let’s face it, complacency breeds stagnation.

AI is the ultimate disruptor, and it’s shaking the foundations of traditional industries.

The companies that embrace AI will thrive, while the dinosaurs clinging to outdated methods will be left in the dust.

As an investor, you want to be on the side of the winners, and AI is the winning ticket.

The Talent Pool is Overflowing: The world’s brightest minds are flocking to AI.

From computer scientists to mathematicians, the next generation of innovators is pouring its energy into this field.

This influx of talent guarantees a constant stream of groundbreaking ideas and rapid advancements.

By investing in AI, you’re essentially backing the future.

The future is powered by artificial intelligence, and the time to invest is NOW.

Don’t be a spectator in this technological revolution.

Dive into the AI gold rush and watch your portfolio soar alongside the brightest minds of our generation.

This isn’t just about making money – it’s about being part of the future.
