Plumber: The COLE Publishing Magazine Exclusively for Plumbing Contractors
Plumber is a United States trade magazine and website serving residential and commercial plumbing contractors and franchisees. Published by COLE Publishing from Eagle River, Wisconsin, it covers everything from repair work and pipe rehabilitation to water conditioning and new construction, together with the business of running a plumbing company. Its official website is plumbermag.com, and its publisher's address is given as COLE Publishing, 415 E. Wall Street, Eagle River, WI 54521.
The title's promise is in its positioning: it exclusively serves plumbing contractors and franchisees. That word — exclusively — separates Plumber from consumer home-improvement media and from general construction titles. Every article, profile and product item is aimed at a professional who sells, installs, repairs or manages plumbing work for a living, whether as an independent owner-operator, a growing local company or part of a franchise system.
Publisher: COLE Publishing's Contractor Family
Plumber is one of nine highly focused trade publications produced by COLE Publishing, a privately held company founded by Bob Kendall and Pete Lawonn in June 1979, with offices in Wisconsin and Minnesota and headquarters in Eagle River. COLE's titles — Pumper, Cleaner, PRO (Portable Restroom Operator), Onsite Installer, Municipal Sewer & Water, Treatment Plant Operator, Gas, Oil & Mining Contractor, digDifferent and Plumber — serve the liquid waste and environmental wastewater industries and the trades connected to them.
The company's origin explains its contractor-first culture. Kendall and Lawonn started after Lawonn, who pumped septic systems, could not effectively market a spare vacuum tank to other contractors; advised that the industry needed its own trade journal, they mailed the first issue of Midwest Pumper to 2,500 contractors in eight states. Plumber applies that same founding idea to plumbing: contractors learn best from a publication built for them, filled with peers' experience and suppliers who serve their trade. COLE, owned by Bob Kendall with Jeff Bruss as president, also founded the WWETT Show, sold to Informa Exhibitions in February 2016, and its magazines continue to participate in that event.
Audience: Contractors, Franchisees and Their Teams
Media directories classify Plumber as a monthly, national, English-language trade magazine, and its own description defines the readership as residential and commercial plumbing contractors and franchisees providing repair work, pipe rehabilitation, water conditioning and new construction. In practice that audience includes master plumbers and journeymen who own their firms, service technicians who run calls all day, estimators and project managers on commercial work, and the office and marketing staff who keep the schedule full.
The franchise audience is distinctive. A franchisee operates a local business under a national brand, balancing independence with system standards, and needs guidance on both craft and business growth. An independent contractor faces many of the same questions — pricing, hiring, marketing, technology — without a franchisor's playbook. Plumber addresses both, often by profiling companies at different scales: the Cleveland-area company that deliberately stays small to offer personalised service, and the third-generation family business using data-driven strategies to evolve, both featured as cover stories in 2024.
Technical Coverage Across the Trade
The technical scope of Plumber is broad because the modern plumbing contractor's scope is broad. Its subject areas, as catalogued from its own positioning, include drain cleaning, new construction, pipeline rehabilitation and repair, pipeline inspection, location and leak detection, septic and sewer installation and repair, hydronic heating systems, commercial plumbing and new commercial construction, service vans and fleet vehicles, well water services and conditioning, fixtures, tools and supplies, and heating, ventilation and air conditioning work where it overlaps with plumbing businesses.
Issue contents show how that scope is handled. A single monthly issue moves from a cover profile to product spotlights — for example, a hydronic radiant heating system presented as clean, efficient and green, and transition couplings offered with press technology — to product focus features on green plumbing products or on pumps, controls and alarms, case studies, and an annual buyer's guide or pumps directory. Technical explainers examine subjects such as the evolution and endurance of drainage fixture unit values in modern plumbing systems, caring for everyday tools so they last, and repairing underground waterlines without disturbing sidewalks.
The Business of Plumbing: Smart Business and In the Shop
Two recurring departments reveal Plumber's dual mission. Smart Business covers the management disciplines that decide whether a technically competent company survives: streamlining customer service so customers call again, recognising why customers leave and keeping them engaged, hiring for adaptability, communication and customer service, deploying new technology tools wisely, overcoming the pains of growth, and preserving a senior technician's knowledge before retirement. In the Shop addresses operations and technology, including the benefits of incorporating green plumbing products and a guide for home service businesses navigating the emerging artificial intelligence age.
Other regular strands include From the Editor, Industry Insider, Industry News, Product News and Product Spotlight, a calendar, and On the Road. Editorials have used data to help companies improve, reflected on a year defined by high prices and hard work, and looked ahead to regulatory initiatives and rising costs. Insider columns have argued for the trade's role in upholding safety, sanitation and public health, called for training and mentorship as the workforce ages, and weighed the effects — including the negative side — of private equity ownership in the plumbing industry.
Contemporary Debates: Private Equity, Giants and Growth
Plumber's recent online coverage shows a magazine engaged with the structural changes reshaping its industry. E-news items in 2026 addressed a plumber fighting the good fight against private equity, how small plumbing companies win against franchise giants online, how to smartly deploy new technology tools, and how to preserve expertise before a best technician retires. Earlier columns considered what a move to private equity means for business owners, employees and customers, and an Industry Insider piece looked explicitly at its bad side.
This willingness to host debate matters. Consolidation, franchising and investor ownership are transforming a trade long defined by independent family firms. A contractor weighing an offer, an employee watching an ownership change, or a small firm competing with a heavily marketed rival all need reporting that treats them as decision-makers. Plumber's profiles support that need with evidence: the owner for whom running his own business was not the plan a few years earlier, now leading a period of rapid growth with a strong vision for the future, is presented neither as a warning nor an advertisement, but as a peer's experience to learn from.
Products, Directories and the Marketplace
Product journalism is a core service. Each issue carries product news and spotlights tied to the season's focus, and the year is punctuated by reference tools such as the annual buyer's guide and the pumps directory. Case studies show products solving real problems: epoxy lining clearing water and restoring flow, a sewer pipe system meeting challenging conditions, green products applied in practice. For manufacturers — from fixture and tool makers to a water tank manufacturer marking 150 years of history — the magazine offers a route to a verified contractor audience.
The commercial pages are matched by practical online resources: commercial plumbing article archives, product coverage reaching back years, and subscription offers that invite readers to receive the magazine free in inbox or mailbox. The subscription pitch is simple — get the insights your colleagues read, delivered free — and reflects the controlled-circulation trade model on which COLE was built: qualify the audience, serve it well, and let specialist advertisers fund the publication.
Print, E-News and Digital Publishing
Plumber publishes monthly in print, with full issue contents posted at plumbermag.com, and maintains a frequent e-news stream between issues. The e-news archive mixes short practical items — observation skills for job site safety, fleet management, sewer line cleaning technique, choosing a plumbing supply partner, human communication as a business skill — with commentary on the trade's identity, including the proposition that plumbers are the mechanics of modern civilisation. Online exclusives extend print topics with invoicing and billing applications, technology investment checklists and product announcements.
That rhythm — a substantial monthly issue for considered reading, plus frequent digital items for immediate use — suits contractors whose learning happens in fragments: between calls, in the office at day's end, or while researching a specific problem. The website's archives, organised by topic and date, turn individual articles into a searchable reference library for the trade.
Values: Craft, Public Health and Workforce
Running through Plumber is a defence of the trade's standing. Its Industry Insider writing has described plumbing's noble call — upholding safety, sanitation and public health — and insisted that as the workforce ages, proper training and mentorship must follow. Editorials on planning for the industry's future return to the same concerns: regulation, costs, and the supply of skilled people. Even a light-hearted cover story about a small company using humour and personal service underlines a serious point: in a trade built on trust inside customers' homes and businesses, character and communication are commercial assets.
Those values connect Plumber to its publisher's wider mission. COLE's titles serve the people who pump, clean, install, treat and plumb — the infrastructure workforce that the public notices mainly when something fails. Giving that workforce professional media of its own, written to a monthly standard since the model was established in 1979, is a form of recognition as well as information.
Why Plumber Matters
For WorldNM readers, Plumber illustrates a durable American trade-publishing model: a narrowly defined professional audience, a magazine written entirely in its language, and a publisher rooted in the industry it covers. From its Eagle River base, Plumber reaches plumbing contractors and franchisees nationwide with technical guidance, business strategy, product intelligence and peer stories, in print and online.
Its distinct contribution is combination. Technical competence alone does not build a plumbing company, and business advice alone cannot fix a line or specify a system. Plumber holds both together — fixture units and family succession, press couplings and private equity, green products and good hiring — in a single monthly conversation with the contractors who keep America's water moving safely.
