Introduction
This manual provides essential information for the proper installation, operation, and maintenance of your Suburban Magnesium Anode Rod, Model 233514. This component is crucial for protecting your RV's water heater tank from corrosion and extending its lifespan. Please read these instructions carefully before proceeding with installation or maintenance.
Safety Information
Always observe the following safety precautions:
- Ensure the water heater is completely drained and cooled before attempting any installation or maintenance.
- Turn off all power and gas supplies to the water heater before beginning work.
- Wear appropriate personal protective equipment, such as gloves and eye protection.
- If you are unsure about any step, consult a qualified technician.
Product Overview
The Suburban Magnesium Anode Rod is designed to protect the interior of your water heater tank from corrosive elements present in water. Made from magnesium with a commercial-grade stainless steel core, it acts as a sacrificial component, corroding instead of the tank lining.
Key Features:
- Corrosion Protection: Magnesium anode absorbs corrosive action, prolonging tank life.
- Durable Construction: Features a commercial-grade stainless steel core for extended rod life.
- Optimized for Water Conditions: Best suited for use in high pH and soft water environments.

Installation Instructions
The anode rod is typically installed in the drain opening of your water heater. Follow these steps for proper installation:
- Prepare the Water Heater:
- Turn off the water heater's power supply (electric breaker or gas valve).
- Turn off the main water supply to your RV.
- Open a hot water faucet inside the RV to relieve pressure.
- Locate the drain plug/anode rod on your Suburban water heater.
- Place a bucket or drain pan under the drain opening.
- Carefully remove the old anode rod using a 1 1/16-inch socket wrench. Water will drain from the tank.
- Allow the tank to drain completely. Flush the tank if desired to remove sediment.
- Install the New Anode Rod:
- Ensure the threads on the new anode rod are clean and apply thread sealant tape (if not pre-applied) to ensure a watertight seal.
- Insert the new Suburban Magnesium Anode Rod into the drain opening.
- Hand-tighten the rod, then use a 1 1/16-inch socket wrench to tighten it securely. Do not overtighten.
- Refill and Test:
- Close the hot water faucet inside the RV.
- Turn on the main water supply to your RV.
- Open a hot water faucet inside the RV until water flows steadily, indicating the tank is full and air has been purged.
- Check for any leaks around the newly installed anode rod.
- Once confirmed leak-free, turn on the power or gas supply to the water heater.

Maintenance
Regular inspection and replacement of the anode rod are essential for maintaining your water heater's efficiency and longevity.
Inspection and Replacement Schedule:
- Inspect the anode rod at least once a year, or more frequently if you notice reduced hot water output or unusual odors.
- Replace the anode rod when it has corroded to approximately 75% of its original diameter, or when it is heavily pitted and worn.
- The frequency of replacement depends on water quality and usage. In areas with hard water or high usage, more frequent replacement may be necessary.

Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Reduced Hot Water Output | Heavily corroded anode rod or excessive sediment buildup. | Inspect and replace the anode rod. Drain and flush the water heater tank. |
| Unusual Odor (e.g., "rotten egg" smell) | Reaction between magnesium anode and certain water chemistries (sulfate-reducing bacteria). | Replace with an aluminum/zinc anode rod (if compatible with your water heater and water conditions) or consult a water treatment specialist. |
| Water Leak at Anode Rod Connection | Improperly tightened rod or insufficient thread sealant. | Drain tank, remove rod, reapply thread sealant, and re-install securely. |
