Plumbing has always been a trade about water and pipes. What is changing across the second half of this decade is the rest of the trade: who installs the pipe, what the pipe is made of, and what the fixtures and water heaters at either end of the run actually do. Three forces are reshaping the industry at once, and a business that wants to be relevant in 2030 has to be paying attention to all three today.
This guide covers the workforce shift redrawing who works as a plumber, the materials and methods revolution led by PEX adoption and heat pump water heaters, and the smart-water technology layer that is turning every fixture into an addressable IoT device. The closing section covers the operational side: how a plumbing business needs to be set up to capture the work.
The Workforce Shift
The plumbing trade is in the middle of a generational handoff, with retirements outpacing apprenticeship entries in many regional markets. Two trends within the workforce side matter most.
Demand Outpacing Supply
The Bureau of Labor Statistics projects employment of plumbers, pipefitters, and steamfitters to grow 4 percent from 2024 to 2034, with roughly 44,000 openings projected each year on average over the decade. The bulk of those openings come from retirements rather than net new positions. The median annual wage hit $62,970 in May 2024, with the top quartile clearing $84,000 and master plumbers in high-demand metros earning well into six figures. Apprenticeship programs across the country are running at or near capacity, and the businesses paying for their own apprentice training are the ones building benches deep enough to absorb the retirements coming through the rest of the decade.
Women Joining the Trade
Women still make up only about 2 percent of employed plumbers, pipefitters, and steamfitters according to BLS data, but that share has been inching up from an even lower baseline a decade ago. The apprenticeship pipeline tells the more interesting story: women now make up a meaningfully larger share of construction-trade apprentices than they do of the working trade, a sign the next cohort will be more diverse than the current one. Once in the trade, women in plumbing earn close to what their male counterparts do, a wage gap that is tighter than the roughly 84 percent national average across all sectors. Industry groups like Women in Plumbing and Piping have built the networks, mentorship programs, and trade-show presence that the previous generation did not have, and the result is a workforce that is slowly but unmistakably diversifying.
Materials and Methods
The pipe in the wall and the appliance on the wall are both changing. The business that quoted exclusively in copper and gas-fired tank water heaters five years ago is now quoting PEX and heat pump units more often than not.
PEX Takes Over
Cross-linked polyethylene tubing is now the default specification for new residential plumbing installations, accounting for more than half of new residential plumbing work in the United States by most industry reporting. Three forces drive the shift: copper commodity price volatility, the labor savings on PEX installs with fewer joints, faster pulls, and no soldering, and PEX's superior freeze-burst resistance in cold climates because the tubing expands rather than rupturing under ice pressure. Manufacturers like Uponor and Viega have built the fitting ecosystems and code-approval portfolios that made the transition practical for production businesses.
Heat Pump Water Heaters
The water heater market is shifting from gas-fired tanks toward electric heat pump units at an accelerating rate, with market researchers projecting the global heat pump water heater market to roughly double over the coming several years. Hybrid heat pump water heaters use substantially less electricity than standard electric resistance units, often cited as up to 60 percent less, by extracting ambient heat from the surrounding air. Federal tax credits under the Inflation Reduction Act once helped offset the install cost, but the 25C and 25D consumer credits were terminated at the end of 2025 under subsequent legislation, so the current incentive picture rests mainly on state and local utility rebate programs. Plumbing businesses should quote from current utility-rebate availability in their service area rather than the expired federal credits. Even so, the underlying efficiency economics, plus the electrification trend, keep the replacement work coming off every retiring tank, and businesses that built their heat pump water heater install certifications early are the ones winning it.
Smart Water Technology
The third force is the smart-water-tech layer being installed alongside the pipe. Fixtures and shut-off valves now ship with IoT connectivity by default, and the plumber on the install is increasingly the one configuring the network setup.
Leak Detection and IoT
The smart water leak detection market is growing quickly, with market researchers projecting it to roughly double over the coming decade. Whole-home systems from Phyn, Moen Flo, and similar players install at the main supply line, monitor flow patterns continuously, and automatically shut off the supply when an anomaly suggests a burst pipe or running fixture. The same sensor data feeds insurance discount programs, with some carriers offering premium reductions for connected leak detection. Plumbing businesses increasingly bundle the install of a smart shut-off valve into every repipe and water-heater-replacement quote.
Connected Fixtures
The fixture side is following the same path. Smart faucets with touch-free activation and water-use tracking, app-controlled toilets with seat warming and bidet functions, and integrated whole-home water-quality monitoring are all moving from luxury install to standard specification on new high-end residential builds and mid-range retrofits. The plumber is still the one running the supply line, but the post-install configuration of the connected fixtures has become part of the job description.
What This Means for Your Business
The business that adapts to these three forces is going to outgrow the business that does not. The shifts are practical: hire and train the apprentice pipeline now, certify on PEX and heat pump water heater installs before the retiring competition gets reassigned to those jobs, and learn the configuration side of the smart-fixture ecosystem so the install is not finished the moment the water turns on. The operational side of the business has to scale alongside the technical side.
Smart Service handles the scheduling, dispatch, customer history, mobile invoicing, and recurring service contracts that a growing plumbing business needs to operate efficiently. The platform ships in three editions matched to the business's QuickBooks setup. Smart Service classic pairs with QuickBooks Desktop for businesses running Pro, Premier, or Enterprise. Smart Service Cloud integrates with QuickBooks Online. Smart Service 365 also integrates with QuickBooks Online with a modern cloud-app feature set. The QuickBooks edition decision guide covers which one fits a given business. For the broader sales-conversation framing techs use in the field on the smart-fixture and heat pump water heater quotes, the technician sales training guide pairs well with the shifting product mix.
The future of plumbing is not one trend but three running in parallel: a diversifying workforce, a material and equipment overhaul, and a smart-water-technology overlay that turns every install into a connected one. A business that captures the upside of all three exits the decade with deeper benches, higher tickets, and a customer base that views it as the technical authority rather than the cheap option.
