Description
The Rheem-Ruud UV99004 is a genuine OEM flexible anode rod designed to protect your water heater tank from the inside out. At 42 inches in length, its flexible design makes installation straightforward even in tight spaces or low-clearance installations where a rigid rod would be difficult or impossible to fit.
How It Works
Anode rods are a critical sacrificial component in any water heater. Made from a reactive metal, the anode rod attracts corrosive minerals and electrochemical activity away from the steel tank lining — essentially sacrificing itself to preserve the integrity of the tank. Replacing a depleted anode rod is one of the most cost-effective ways to dramatically extend the service life of a water heater.
Key Features
- Flexible design for easy installation in low-clearance and confined spaces
- 42-inch length provides maximum sacrificial surface area for long-lasting tank protection
- Genuine Rheem-Ruud OEM replacement part — engineered to factory specifications
- Helps prevent tank corrosion and rust, extending water heater service life
- Compatible with select Rheem and Ruud water heater models
Why Replace Your Anode Rod?
A depleted or missing anode rod allows corrosive elements to attack the tank walls directly, leading to premature tank failure, rust-colored water, and costly replacements. Routine anode rod inspection and replacement is a best practice recommended by water heater manufacturers to maintain warranty coverage and maximize equipment longevity.
