Commercial & Architectural Lavatory Drains
Engineered with zero-lead brass and high-velocity hydraulic channels, our flagship pop-up and offset assemblies meet rigorous hospitality, healthcare, and multifamily installation requirements.
Precision Fluid Dynamics & Metallurgical Integrity
Why Tier-1 plumbing brands and master distributors require heavy-gauge solid brass, lead-free forging, and micron-accurate threads for commercial washroom infrastructure.
Dezincification-Resistant Brass
Standard yellow brass is susceptible to aggressive dezincification in acidic municipal water conditions. JANA engineers utilize proprietary DZR brass alloys (CW602N / C36000 compliant) that prevent leaching, retaining structural tensile strength across decades of pressurized service.
Hydrodynamic Vortex Elimination
By conducting computerized finite element analysis (FEA) on internal core bodies, our engineering department sculpts the internal transition geometry of our pop-up bodies to reduce shear stress, eliminate micro-eddies, and maintain maximum evacuation rates.
Micro-Engineered Sealing Mechanics
Our pop-up stoppers and umbrella drains utilize chemical-resistant Santoprene and EPDM O-rings paired with cycle-tested stainless steel springs (rated to >100,000 actuation cycles), completely outlasting cheap die-cast zinc alternatives.
Meeting Sector-Specific Plumbing Challenges
From high-turnover luxury hospitality spaces to ADA accessibility compliance, our engineering matrix matches precise market requirements.
Hospitality & Luxury Multi-Family
Guest satisfaction hinges on rapid sink drainage and silence. Our brass umbrella drains (JN-5012 series) feature oversized caps to deflect standing water and high-grade acoustic dampening gaskets that eliminate hollow drainage noise in five-star hotel developments.
ADA Barrier-Free Public Restrooms
The Americans with Disabilities Act mandates clear knee clearance under commercial vanities. Our JN-5001 and JN-5003 Offset Lavatory Drains route wastewater backward toward the wall, shielding wheelchair users from contact with scalding pipes and maximizing space.
RV, Marine & Modular Construction
Prefabricated building envelopes and recreational vehicles operate under severe spatial and vibration constraints. Our hybrid brass-ABS pull-out assemblies deliver light weight, crack resistance under structural flexing, and rapid push-fit connectivity.
Dual-Origin Resilience: Mitigating Geopolitical & Tariff Risk
Operating synchronized smart manufacturing plants across Yuhuan, China, and Kabinburi, Thailand, JANA provides importers with uninterrupted fulfillment, zero tariff shocks, and unified quality protocols.

Technological Roadmap & Sustainable Manufacturing
How JANA Plumbing is redefining commercial drain systems for next-generation environmental standards and smart buildings.
Eco-PVD Finishes
Transitioning from hexavalent chrome electroplating to state-of-the-art Physical Vapor Deposition (PVD). Eliminates hazardous waste while providing 10x greater scratch and corrosion resistance for Matte Black, Brushed Nickel, and Satin Brass.
Zero-Lead Metallurgies
Anticipating stricter global drinking water and sanitation standards, our R&D wing produces silicon-alloyed and bismuth-stabilized brass alloys with negligible (<0.05%) trace lead content, exceeding NSF/ANSI 372 standards.
Anti-Clog Hair Strainers
Integrated micro-mesh removable internal catchers engineered within standard pop-up bodies. Traps debris prior to the P-trap, slashing maintenance calls in large multifamily residential developments.
Rapid "No-Tool" Mounting
Revolutionary segmented threaded slip-nuts allowing contractors to slide the locknut into place and secure it in 15 seconds, slashing contractor installation labor on major commercial high-rise projects by 40%.
