Lifetime warranty on Rheem Marathon water heater
Typical Processing Time: Approved claims for part or labor reimbursement generally take 4 to 8 weeks to be finalized and credited to the original payment method.
Reason for Common Delays: Claims are frequently denied if the unit was never registered or if the failure was caused by sediment/scale buildup, which is considered a maintenance issue rather than a manufacturing defect.
Helpful Tip to make the claim easier: Always perform the Rheem warranty registration within 90 days of installation. Failing to register your product online can significantly shorten your coverage period, often defaulting a 10-year or 12-year limited warranty down to a standard 5-year term.

Exclusions & Limitations
If the tank itself is leaking due to a manufacturing defect within the warranty period, Rheem will typically provide a replacement water heater of a comparable current model. Note that you are responsible for the labor costs to remove the old unit and install the new one.
These are located on the rating plate, a large silver or white sticker on the exterior of the tank or HVAC cabinet. The model number usually begins with letters (e.g., XE, PRO, or RTG), and the serial number is a unique alphanumeric code required for all support requests.
The Marathon series features a seamless, blow-molded polybutene tank that is "warranted not to leak for as long as you own your home." To secure this Limited Lifetime Warranty, the unit must be registered online within 90 days of purchase; otherwise, it defaults to a 10-year warranty.
Generally, Rheem residential warranties are non-transferable and apply only to the original purchaser at the original installation address. Once the home is sold, the warranty typically expires or reverts to a much shorter base period.
Yes. Units purchased at retail stores like The Home Depot are covered by Rheem's manufacturer warranty. For claims, you can either contact Rheem directly or visit the Home Depot service desk with your original receipt and product details to facilitate a return or exchange if applicable.
You can verify your coverage using the Rheem Warranty Verification tool. You will need to enter your unit's serial number, which is located on the rating plate (sticker) on the side of your water heater or HVAC unit. The tool will display the original installation date and the remaining coverage period.
Product registration can be completed online through the Rheem warranty page. For many products, such as the Marathon series, registering within 90 days of installation is required to upgrade a standard 10-year warranty to a limited lifetime warranty.
To initiate a claim, you should first contact the licensed professional contractor who installed the unit. If you are handling it yourself, contact the Rheem Warranty Department at 1-800-431-1549. You will need your model number, serial number, and proof of the installation date.
Coverage varies by model line. Standard Performance models typically offer a 6-year tank and parts warranty, while Performance Platinum models offer up to 12 years. If the unit is installed in a multi-family or commercial building, the tank warranty is often reduced to 1 year.
Most standard Rheem limited warranties cover parts only and do not include labor, shipping, or disposal fees. Some high-end models may include a 1-year labor allowance, but for long-term protection, homeowners typically must purchase a third-party extended labor warranty.
