In a water heater, an anode rod, also referred to as “sacrificial” rod, is consumed as it “gives up” its electrons to protect the carbon steel tank (cathode). Magnesium rods are excellent sacrificial rods, used to protect the inside metal surface of your water heater tank. Some of these dissolved minerals, like magnesium, in your hot water system can be advantageous for most people to drink, should the hot water be used for consumption. Periodic flushing of the tank with bleach solution will reduce the problem. Waiting a long time is not a good idea. Compare the new water heater anode rod on the top (what we sell) to a one year old anode-rod below. Please read our FAQ for more information regarding water odor. Replace the anode rod(s) with a less reactive material (magnesium to aluminum, or aluminum to aluminum alloy). This will cause cracks in the glass lining of the water heater radically shortening the life of the water heater. Anode rods installed into water heaters by the manufacturers will generally be made of magnesium or aluminum that is wrapped around a steel core wire. A. Anode rods should be only a few inches shorter than your water heater. The possibility of the old water heater anode rod becoming broken off, It “gives up” electrons more freely than aluminum. See Service Bulletin 109 – Hydrogen Sulfide Odor and Chlorinating Water Heaters. 5 Stars, 9 product ratings … Sanitizing the water heater (with safe levels of bleach, etc), will eliminate the odor but only for a variable (relatively short) length of time.

However, if you are concerned about other dissolved elements in your water, then we suggest you get your water tested by a qualified laboratory or not use your hot water for drinking water. Water chemistry not only affects conductivity and how quickly the anode is consumed, but also contributes to situations like “rotten egg smell.”. water and how much water travels through your water heater. You might also consider flushing your water heater out at least once a year as a normal maintenance procedure. The gel can be either milky or clear and is often mixed with other water heater deposits such as scale, rust, or tiny sediment particles. The aluminum oxide forms a virtually odorless "gel" substance that can vary in texture from a firm somewhat sticky curd to a thick running slurry. Please note that the condition of your water and the quality of the water heater lining are two other factors that affect the life span of your water heater. One of the most critical factors in how long a water heater will last is the condition of the water heater sacrificial anode rod. 9 product ratings. The flexible aluminum anode rod can be bent at the two joints as needed during installation. A water heater sacrificial anode rod is a metal rod and is generally screwed into the top of the tank. Is that true and if so, if I remove the anode rod will the odors go away?" All of our anode rods are designed for standard 3/4" NPT water heaters. The seat is equipped with a safety relief port. Q. "As the anode rod dissolves, is water from the hot water line safe to drink?" “Air” or “sputtering” in the hot water when faucets are turned on. An integral 2-1/2" heat trap nipple included with 42-1/2" length and 4" heat trap nipple included with 35" length.

Certain water conditions will cause a reaction with magnesium or aluminum anode rods to produce a "rotten egg" smell. The amount of the mineral content dissolved from an anode rod in your water is greatly diluted and normally falls below acceptable allowable levels found in water. The anode rod … Right Spec® Sizing & Cross Reference Tools. This hot water outlet flexible anode rod has a 3/4" Mipt x 5 " built-in dielectric nipple without a restrictive ball or seat to allow greater water flow than a heat trap nipple. The anode rod is the most important factor in determining the life of your water heater. The single most important factor in tank life is the condition of its anode. Just bend the anode rod at its flexible sections and insert into opening at top of water heater one section at a time until all sections are inserted. softened water or lower pH levels, this sacrificial process is accelerated; in those cases, aluminum is a better choice. Q. Anode rods are designed to attract corrosive elements in the water, thereby diminishing corrosion in the vulnerable steel liner. Magnesium is a leading anode material given its ability to best protect the steel tank. Water test parameters to consider: Overly softened water will increase conductivity. These devices work because the metal in the rod is more easily corroded than the metal of the water heater tank. non-sacrificial rods (meaning they don’t degrade like a normal anode rod) which use electrical pulses to deal with corrosive elements in your water When sodium is added to the water (such as when a water softener is used), anode rods can This type of anaerobic bacteria feeds off the hydrogen gas produced by magnesium anode rods. Do you know the condition of your anode rod? The two main factors that contribute to anode activity are anode material, and water … 2 Partially drain the water heater. Stop Tank Corrosion. Indications that water testing and/or anode material change may be needed include, but are not limited to: For air in the hot water lines, service action includes: With smells or discoloration in the water, BWC recommends draining the hot water system and chlorinating the water heater and hot water piping. Some replacement rods … Before performing any work on a water heater, you should always turn off the circuit breaker or turn off the thermostat on gas models. Q. Magnesium anode rods tend to be consumed quicker than Aluminum or Aluminum/Zinc/Tin anode rods due to the higher voltage they create during the sacrificial process. Just make sure that the anode rod is not touching the side of the water heater once completely inside. The anode rods are designed to draw corrosion away from the tank, and into the rod … Aluminum anode rods are the least expensive and create the lowest voltage during the sacrificial process. The best part of using the aluminum anode rod is for places where there are a lot of sulfates present in the water. Low ceiling? It’s job is to attract corrosive elements in your potable water. The Ultra Flexible Magnesium Anode Rod has four sections of magnesium attached with copper or stainless steel couplers and 301 stainless steel braided wire providing greater flexibility during installation. and then falling to the bottom of the water heater (and then bouncing around whenever water travels inside the water heater) is what will deteriorate the water heater tank lining very quickly. The magnesium will corrode and disintegrate long before the stainless steel braided wire ever can. Or maybe your existing anode rod is difficult to remove due to corrosion on the top of the water heater. Our titanium water heater anode, combined with electrical current will provide added corrosion protection and increase the life of your hot water tank.Our Powered Anode Rod … If the anode rod is too long, they can be cut down using a hacksaw.

These metals include aluminum, … Water temperatures of about 140°F - 170°F makes for a rich growth medium. Most water heater manufacturers install these in their water heaters as standard equipment. The negatively charged electrons create a higher voltage to flow from the anode rod to the steel tank causing the anode rod to corrode instead of the steel water heater tank, or other exposed metals such as electric elements. 1 Turn off water and fuel supply (gas or electricity) to water heater. You see, the anode rod, which is usually made from magnesium, succumbs to corrosion before other components of the water heater, like steel, will. Service Bulletin 109 – Hydrogen Sulfide Odor and Chlorinating Water Heaters. Details about Suburban Mfg Water Heater Anode Rod 232768. It provides many health and environmental benefits and is an essential element in all living things. These allow the installation of an anode rod for those instances when the normal anode rod has corroded too much causing the steel to rust or corrode in such a way it is now impossible to remove the old rod. This material is most effective for protecting the heater and is less likely to cause odors in hot water. They don’t produce nasty sediment problems, and they’re reactive enough to neutralize problems in acidic water. This means they will usually corrode at a slower rate than the other anode rods we offer. Read reviews. This style of anode rod installs into the hot water outlet of the water heater and yet allows the water to still flow through the outlet. Most gas or electric water heaters require a standard rod length of 44”. Unpleasant taste or odor coming from your hot water outlets can be caused by natural occurring iron bacteria in the water. By replacing the magnesium or aluminum anode rod with a combination aluminum/zinc/tin anode rod you may help decrease this smell, but it may not eliminate it completely. The anode rod is designed to act as a less noble material than the Steel tank of the water heater. A. This is so that water will disintegrate the anode rod long before it does the water heater, thus lengthening it’s lifespan. A. Iron bacteria does not produce hydrogen sulfide, the "rotten egg" smell, but can cultivate an environment where sulfur bacteria can grow and produce hydrogen sulfide (the rotten egg smell). "I have a sulfur odor smell coming from the hot water side of my faucets. Water Heater Anode Rods: Aluminum vs Magnesium – Our Conclusion. In a water heater, an anode rod, also referred to as “sacrificial” rod, is consumed as it “gives up” its electrons to protect the carbon steel tank (cathode). As Aluminum anode rods corrode they can produce an aluminum oxide deposit normally found at the bottom of water heaters, but occasionally make it into the main water supply and into faucet aerators. Over time the rods get “sacrificed” for the healthy survival of the heater’s tank and the result can lead to smelly water. In many cases the odor is hydrogen sulfide gas. Sectional connections are made with copper couplings and 301 stainless steel braided wire. If your gas water heater has a “Vacation” setting, that will allow you to work on the unit without relighting the pilot afterward. Zinc oxide and zinc compounds are indigestible to micro-organisms such as bacteria. Anode rods generally last about five years but it really depends mostly on the quality of your This combo rod is designed to fight some foul water odors that can occur in water heater systems that use aluminum or magnesium anode rods.
