Rust-colored or discolored hot water from Reliance water heater

Safety first: Turn OFF power or gas. Allow water to cool somewhat before draining. Rusty water can stain fixtures; protect surfaces.

Steps to check:

• 1. Flush tank: Attach a hose to the drain valve and flush several gallons until water runs clearer. This may temporarily reduce discoloration.
• 2. Inspect anode rod: Remove the anode rod from the top of the heater (often under a plastic cap). If it is heavily corroded or less than 1/4 inch thick, replace it with a new Reliance-compatible rod.
• 3. Evaluate age: If the heater is near or beyond its expected service life (often 8–12 years) and rust persists, internal tank corrosion may be advanced.
• 4. Consider filtration: If incoming cold water also shows rust, install or service an iron filter or whole-house filter.
• 5. Plan for replacement: Persistent rust from the hot side only, especially with an old heater, usually indicates the tank is deteriorating and should be replaced before it leaks.

Note: Use a proper torque wrench and avoid overtightening the new anode rod to prevent tank damage.
