You can cut your sacrificial anode, whether it is magnesium or aluminum, in order to replace it. To do this, use a pair of gloves and a saw and cut as you remove the old anode. In confined spaces, this technique is often used.

    Can I change the magnesium anode to an aluminum anode (in the hot water valve) and still install the corro protec (horizontally installed where the relief value was) .

    Currently i have an magnesium anode and i want to replace this with an aluminum anode + add the corro protec to get double caution as the well water has very high sulfur and a very noticeable odor.

    thanks s

      Hello Steven,
      This is a very good question. You don’t need to remove or replace the original magnesium anode if you install the Corro-Protec on a Bradford White water heater. If you want to go ahead and do that, it will work fine too.
