Why Do You Need Water Heater Pans and Stands?
Water heater pans protect your home from costly water damage by containing leaks and directing water to drain lines. A single water heater leak can cause thousands of dollars in damage to flooring, subfloors, and personal property and, if your water heater is on an upper level, the ceiling and walls below. Drainage pans for water heater and washing machines provide early leak detection, floor protection, and code compliance for installations in attics, upper floors, or above finished living spaces.
Water heater stands elevate gas water heater tanks 18 inches above the ground to comply with the National Fuel Gas Code (NFPA 54). This elevation is required for gas water heaters installed in garages and other areas where flammable vapors from spills may accumulate near the floor. The 18 in. height raises the ignition source above the level where gasoline vapors and other flammable gases typically settle, providing essential safety protection.
Key Benefits:
- Leak containment: 2-½ in. to 3 in. deep drainage pans hold water from minor leaks, drips and water discharge
- Floor protection: Prevents water damage to subflooring and surrounding areas
- Early detection: Visible water in the pan alerts you to problems before major damage occurs
- Multiple drain adapter options: Pans include 1 in./1-1/2 in. PVC and 1 in. CPVC drain fittings for flexible installation
- Fire protection: Stands safeguard gas water heaters with an ignition source from potentially flammable vapors due to spills inside of garages.
- Flood protection: Stands elevate water heaters above potential ground-level flooding
- Code compliance: Meets relevant Uniform Plumbing Code (UPC), IPC, IRC, IMC, NSPC, National Fuel Gas Code (N), and local building code requirements
What Types of Water Heater Pans Does Oatey Offer?
Oatey manufactures aluminum pans for gas water heaters, plastic pans for electric water heaters, and plastic washing machine pans for laundry applications. Each pan type is engineered for specific use cases and code requirements.
Aluminum vs. Plastic Water Heater Pans
Aluminum pans are required for gas water heater installations and approved for electric water heaters. Plastic pans are approved for electric water heater installations only and cannot be used with gas water heaters due to fire safety and temperature resistance requirements.

Washing Machine Pans
Washing machine pans protect laundry room floors from leaks, overflows, and hose failures. These durable plastic pans are specifically designed to fit under washing machines and contain water until it drains safely, protecting floors and surrounding areas from water damage.
Water Heater Stands
Oatey's water heater stands are constructed from 18-gauge spangled galvanized steel delivering a stable base that prevents tipping. These stands elevate water heater tanks 18 inches above the ground in compliance with the National Fuel Gas Code (NFPA 54). Raising the unit also reduces risk from flooding and prevents moisture damage to the base from concrete and dirt floors— providing a stable, corrosion-resistant platform for residential and commercial installations.
