Aluminum Water Heater Drain Pan 20 in ID x 22 in OD - Durable Drainage

In this review the Aluminum Water Heater Drain Pan is evaluated as a practical, no-frills solution for protecting floors and surrounding fixtures from water heater leaks or runoff. The single biggest reason to buy is its simple reliability: a heavy-duty aluminum pan with a included 1 in PVC fitting that lets most installers route leaks safely to a drain. For homeowners or plumbers who need a basic drain pan sized for a typical gas water heater, this model delivers straightforward protection without complicated installation.

Key Features

• Durable construction: The heavy-duty aluminum body resists corrosion and provides structural support beneath a gas water heater.
• Integrated drain fitting: Includes a 1 in PVC fitting so the pan can be connected to a drain line quickly and without sourcing extra parts.
• Correct sizing: The 20 in inner diameter and 22 in outer diameter match common gas water heater bases for a proper fit and coverage.
• Prevents water damage: Designed to catch leaks or runoff and direct water away from floors and nearby fixtures through the drain connection.
• Easy installation: The pan and drain fitting are ready to install, making it suitable for retrofit jobs or new installations.

Who It's For

This drain pan is aimed at homeowners, landlords, and plumbers who install or replace gas water heaters and need a compact, effective way to manage leaks. Its included PVC fitting and standard dimensions suit routine repair or replacement work where a basic pan is required.

It is not intended for electric water heaters with special electrical clearance requirements or applications that demand thicker, structural pans for heavy-duty commercial environments; buyers needing extra-thick steel or integrated alarm systems should look elsewhere.

Pros & Cons

Pros

• Includes a 1 in PVC drain fitting so no additional drain adapter is required for most installs.

• Standard 20 in ID by 22 in OD sizing fits many gas water heaters without modification.
