304 Stainless Steel Tankless Water Heater Drain Pan

Protect your home from costly water damage with this heavy-duty 304 stainless steel drain pan, designed specifically for wall-mounted tankless water heaters. Engineered to catch condensate drips and minor leaks, this drip pan safeguards drywall, flooring, and ceilings from moisture. The construction features a durable silver powder coating over food-grade 304 stainless steel, ensuring superior rust resistance in damp utility-room environments. Unlike carbon steel pans that rust once the coating is scratched, this pan remains rust-free due to the underlying corrosion-resistant material, offering long-term peace of mind.

The bottom drain design ensures complete gravity drainage when installed level, preventing stagnant puddles, scale buildup, and mineral deposits. This design is particularly suitable for tankless heaters with adequate vertical clearance below the unit. The pan measures 20″ x 13″ x 2.5″, providing a universal fit for leading brands including Rheem, Navien, Rinnai, and Noritz. The 2.5″ side wall height is sufficient to catch condensation and minor leaks before they cause significant damage to your home's structure.

The product comes with a professional core kit, including the pan, a T-shaped drain valve, and a flexible drain hose. Mounting screws and wall anchors are not included, allowing you to select the correct fasteners for your specific wall construction, whether wood studs, metal studs, or concrete. For secure installation, it is recommended to fasten the pan into wall studs or add a reinforced backboard to support the weight of the water-filled pan. Always test the basin for water tightness before final wall mounting and check local plumbing codes for drain-fitting material requirements.
