4. REMOVING THE OLD ROD

Following safety precautions, the next step is the removal of the existing magnesium rod. First, use a wrench to loosen the fitting that holds the magnesium rod in place. This may require some force, as the rod can be tightly secured due to mineral deposits. It is wise to anticipate resistance, especially in systems where the rod has not been changed for several years.

Once loosened, carefully pull the old magnesium rod out of the tank. Be conscious of corrosion or rust that might be present, which can create sharp edges. If the old rod is stuck, consider applying a penetrating lubricant to assist in loosening it. It’s pertinent to check the condition of the old rod—typically, a rod should be replaced once it has diminished significantly, often to less than a few inches in size. Documenting the state of the old rod can provide insights into operational longevity and system performance in the future.

5. PREPARING FOR THE NEW ROD INSTALLATION

Once the old magnesium rod is removed, the next logical step involves preparing for the installation of the new rod. Thoroughly clean the area where the old rod was situated, removing any debris or mineral build-up that could hinder the new rod from achieving a proper seal. This is crucial for avoiding potential leaks or future malfunctions.

After cleaning, it is advisable to apply Teflon tape to the threads of the new magnesium rod. This serves as an additional barrier to help prevent leaks and ensures a snug fit. Teflon tape should be wrapped clockwise around the threads so that it does not unravel while inserting the rod. Taking the time to prepare properly for installation can contribute significantly to the effectiveness of the new component and the overall health of the system.

6. INSTALLING THE NEW MAGNESIUM ROD

Having prepped adequately, it’s now time to install the new magnesium rod. Insert the new rod into the opening, ensuring it fits snugly against the tank. It should go in smoothly without excessive force; if the resistance is encountered, reassess and ensure no debris is obstructing the path.

After placing the magnesium rod, use a wrench to secure it. Ensure that it is tight enough to seal but not overly tight, as this could damage the threads. Care must be taken during this step because over-tightening can lead to strip threads or worse, damage the tank itself. After securing the rod, check for any alignment issues. A well-installed rod should run parallel to the tank’s inside, ensuring optimal functionality and protection against corrosion.

7. REFILLING AND RESTARTING THE SYSTEM

With the new magnesium rod securely installed, the next phase is to refill the system with water. Gradually open the water supply valve, allowing the tank to fill slowly.
