Can You Cut Water Heater Anode Rod?

Yes, you can cut your sacrificial anode rod, whether it is magnesium or aluminum, to replace it. To do this, use a pair of gloves and a saw and cut as you remove the old anode. However, when you cut the anode, make sure that the bottom part does not fall into the bottom of the tank, as you will not be able to pull it out.

In confined spaces, cutting the anode rod technique is often used. Make sure to dispose the old anode rod in a safe way and as per your environmental waste regulations in your municipality.

If you don’t have enough space and you are tired of changing the anode rod, you should install a powered anode. Only 12 inches long, this anode is made to last over 20 years.

    QUESTION:

    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.
      Thanks,
      Vincent

      We suggest replacing one of the magnesium anode with a Corro-Protec powered anode rod. This will take care of the smell and the corrosion.

    My AO Smith Promax 40 gallon propane water heater is 22 years old. We have well water so we use a water softener to treat it. My question is should I even bother to change the anode rod or just let run until it dies?

      Replacing the anode would be the best thing to do to make sure you keep it for many years.
