Josam Company

What Josam Company does

Josam Company is a US-based manufacturer of commercial plumbing and drainage products, operating as a subsidiary brand of Watts Water Technologies (NYSE:WTS). Founded in 1987 and headquartered in Michigan City, Indiana, the company employs 51–100 people and sells through a network of authorized sales representatives across all US states, with a dedicated representative office in Xiamen, China, for Asia-region support. Josam serves architects, engineers, contractors, and specification writers in commercial construction, with documented project references across airports, healthcare facilities, food and beverage, automotive, and institutional buildings.

The company's product portfolio is organized into four core lines: cast iron and PVC specification drainage (carriers, roof and floor drains, interceptors, cleanouts, hydrants, trench drains); stainless steel drainage in 304 and 316L grades (floor drains, trench drains, cleanouts, retrofit liners, slot and shower channels); the PRO-PLUS SMC/GRP trench drain system, which is positioned as lighter and stronger than polymer concrete, polypropylene, and HDPE alternatives; and a 316L stainless steel push-fit pipe and fittings system with labor-saving joint design and a pressure rating at least four times higher than competing push-fit products. The portfolio is supported by multiple proprietary technologies, including the patented Jiffee Joint gasket, the WEJLOC clamping system, the PRO-SNAP grate securing mechanism, and Super-Flo strainer technology, alongside ISO 9001, NSF/ANSI 61/372, ASME A112.6.4, and UL 94 HB certifications.

Josam generates revenue through hardware sales of these drainage products, with pricing handled rep-by-rep rather than published publicly. The go-to-market is specification-driven: the company invests in Lunch & Learn training, a gamified eLearning platform, MasterSpec document integration, Revit drawing libraries, and a 728+ project reference database to drive product adoption at the design stage. The company also markets 100% domestic-compliant product options for federal and infrastructure projects subject to Buy America-style procurement rules. There is no indication of recurring software, subscription, or service revenue; the business is a traditional specialty industrial manufacturer.

Direct peers

• ACO Group: ACO is a leading global manufacturer of trench drain systems and surface water management products. Directly comparable to Josam's PRO-PLUS trench drain line and competing in commercial, food/beverage, and infrastructure drainage applications.
• Sioux Chief Manufacturing: Sioux Chief manufactures plumbing drainage and rough-in products including floor drains, carriers, and DWV components. Comparable to Josam in commercial plumbing drainage with a focus on specification-grade products.
• MIFAB: MIFAB manufactures specification-grade plumbing drainage products including floor drains, cleanouts, carriers, and trench drains, targeting the same commercial specifier channel. Strong direct competitor in cast iron and stainless drainage.
• Jay R. Smith Mfg. Co. Jay R. Smith manufactures cast iron drainage products, carriers, roof drains, and specification plumbing drainage — and is itself a Watts Water brand, meaning it competes directly with Josam inside the same parent. Highly comparable product lines, customer base, and channel approach.
• AB&I Foundry: AB&I Foundry is a US manufacturer of cast iron soil pipe and fittings used in DWV and drainage applications. Directly comparable to Josam's cast iron drainage line, particularly for federally funded and infrastructure projects requiring domestic content.
• NDS (NDS Inc.): NDS manufactures drainage and stormwater management products including trench drains, channel drains, and catch basins. Comparable trench drain offering to Josam's PRO-PLUS line, with stronger presence in the residential/landscape channel.
• Zurn Elkay Water Solutions: Zurn Elkay manufactures commercial drainage, water systems, and plumbing products including floor drains, carriers, and trench drains. It is the closest direct competitor to Josam across cast iron, stainless, and trench drain categories serving the same architects, engineers, and contractors.

Broad incumbents

• Watts Water Technologies: Josam's publicly traded parent (NYSE: WTS) and a much larger incumbent in plumbing, drainage, and water quality products. Overlaps with Josam on commercial drainage but serves a far broader portfolio including valves, heating, and water treatment.
• Oatey: Oatey is a large, established manufacturer of plumbing products including drainage, solvents, and supply line components. Overlaps with Josam in plumbing drainage fittings and serves a similar trade contractor base but with a much broader portfolio.

Emerging players

• Fernco (Fernco Inc.): Fernco manufactures plumbing and drainage couplings, connectors, and sealants. Adjacent to Josam's drainage push-fit and coupling offerings, with overlap on push-fit and flexible coupling product categories but less focus on full drainage systems.
