Camco 20840 Aluminum Water Heater Drain Pan 22 Inch Id

Product Description

The CAMCO 20840 is a 22-inch inner diameter aluminum drain pan designed to catch water heater leaks and prevent floor damage in residential installations. The pan measures 22 inches ID and 2.25 inches deep, providing meaningful containment capacity beneath standard water heater tanks. A pre-cut side opening accepts the included dual-size PVC drain fitting, which fits 1-inch to 1.5-inch drain line connections. The aluminum construction resists rust, corrosion, and cracking, making it a reliable long-term solution under both gas and electric water heaters. Licensed plumbers and mechanical contractors typically install this pan during new water heater installations or replacements.

This drain pan is suited for residential gas and electric water heater installations where local plumbing codes require secondary containment. The pre-cut drain port and included fitting allow connection to a standard floor drain or routed drain line without field modifications to the pan itself. Its 22-inch ID accommodates most standard residential tank-style water heaters.

Installation Notes

Installation is typically performed by a licensed plumber in accordance with local plumbing codes and the International Plumbing Code (IPC). Shut off the water supply and power or gas to the water heater before beginning any service work. Connect the included PVC fitting to the pre-cut side opening and route the drain line to an approved discharge point per local code requirements. Do not overtighten the PVC fitting, as aluminum threads can strip under excessive torque.
