Waterheater rod
Hello all,
I have read and heard that there is a special rod in a water heater. The idea, I guess, is to keep the tank from rusting inside. Not sure how. Anyway, we bought our house about 4 years ago and as part of the deal had a new water heater put in. Is there a way to see this rod? Is it something to worry with? Is it something a generally handy type person can do? Thanks, Fred |

Yea, I read that site, I figured it was someone just trying to sell
his/her wares. I did not know if it was propaganda or not. BobK207 wrote: Fred Wilson wrote: Hello all, I have read and heard that there is a special rod in a water heater.

Waterheater rod
Its a legit idea, but the hassle and possible damage or causing a leak
isnt worth it to me. So every 8 to 12 years I install a new tank, thats not much money in comparision with everything else it costs to live. From say age 20 young adult to age 70 say 5 tanks at 500 bucks each. $2500 bucks for a lifetime... Now compare that to likely twice as many new cars in the same time period. 20 grand times 10 is $200,000 plus insurance repairs etc etc........ Hot water tanks are cheap.......... |

Thanks, Fred http://www.waterheaterrescue.com http://www.waterheaterrescue.com/pag...intenance.html cheers Bob Fred- As Hallerb says ....it's a legit site but I agree with him about the hassle / savings analysis except in my case (must be water conditions) my w/h's last even longer. I replaced a w/h heater in 1980 & then in 2004. The 1980 unit was replacing one installed in 1963 (not my install) So I'm getting something like ~20 years per w/h If I "properly" maintained the w/h how much longer would it last? So I jsut forget about it. Of course if your live where the water chem is a problem then maybe replacing the anode might make sense. YMMV cheers Bob |

What was needed was a six pointed socket 1-1/16", breaker bar, and a 4 foot section of pipe for extra leverage. What I found was the top 12" of the anode rod was deteriorated, but the rest of the rod was just fine. Put the rod back with teflon tape for easier removal the next time. I also purchased a "segmented" replacement anode for easier installation the next time. Just remember to turn off the gas, and the incoming cold water, and to drain a few buckets of water from the unit before you start the process. Go slowly, and don't force anything. |

Just remember to turn off the gas, and the incoming cold water, and to drain a few buckets of water from the unit before you start the process. Go slowly, and don't force anything. I also checked mine recently on a a gas heater that is about 5 years old now. The rod appeared to be about half way through it's life. I'll recheck in about 2 years. Certainly the concept behind this is sound and well known. The rod is a sacrificial anode, made of a less noble metal, (magnesium I think), which will corrode instead of the tank. It's the same principle used on every boat, where zincs are used to protect underwater metal. I guess the remaining question is if it will in fact extend the life of the heater enough to make it worthwhile to check and replace the anode. It would seem that it should, because if it didn't significantly protect the tank, the manufacturers wouldn't install them. Plus, checking it gives some indication of how much corrosion is going on. If you see a rod decaying away rapidly, even if you choose not to replace it, you know that the heater is in an environment where it's not likely to last a long time. |

With a 4' section of pipe for extra leverage, how did you keep the tank from turning? Did you have a clearance problem from tank top to ceiling? Bob S. |

I believe that I got the segmented replacement anode rod from them. 2. I did not have a problem with the tank turning when the 4' section of pipe was used for extra leverage. The 50 gallon tank was more than 3/4 full when I removed the anode rod. However, I applied constant pressure on the pipe, rather than a hard tap, jolting motion. 3. I did have a ceiling clearance problem, but was able to raise the anode rod high enough to see that only the top few inches was corroded, but the remaining length of the rod was still the full diameter. Note - the replacement anode rod was segmented - the individual sections are about 12" long, connected together by flexible braided wire. |

I had to use an impact wrench on mine to break it free. With a tank full of water, its usually not a problem to keep it from turning, especially if you have a helper grabbing the tank. An impact wrench works wonders too. Once lose, its easy to remove. Its usually so far gone that its fairly flexible and can be bent to clear the ceiling. Putting a new one in is different. HD sells flexible rods just for this purpose. dickm |

I set it so that the water is just a little hotter than I like for a shower. Mark |

Two issues with this whole subject, my water heater is in a very tight
space. Two, I can not seem to locate a separate rod so I suspect one of the water ports is the anode.
