Description

Corro-Protec’s titanium powered anode rod is designed to last 20+ years and provides continuous protection, unlike magnesium and aluminum anode rods that depletes over time. Corro-Protec requires no maintenance & its 12-inch design makes replacement easier in tight spaces, unlike sacrificial anodes. Corro-Protec helps solve some of the most common hot water issues linked to sulfur smell, tank corrosion, sediment and scale buildup, and air in hot water lines. Learn why powered anode rods are ideal for all water hardness levels, water qualities and water sources. Swipe through the images to see the 4 key benefits and how Corro-Protec’s powered anode rod helps protect your water heater, reduce maintenance and support long-term performance. Use Corro-Protec to get rid of sulfur smell in hot water, no matter the cause, including your water heater, its existing anode, SRB or well water. Corro-Protec is a reliable, cost-effective and time-efficient solution to a persistent problem, requiring no maintenance or chemicals like hydrogen peroxide. If cold water smells too, it will keep hot water from smelling worse than cold, which is already a meaningful benefit since sulfur odor is often noticed first in hot water. Corro-Protec protects internal welds and weak points from corrosion to help prevent water heater leaks and extend water heater lifespan. Unlike magnesium, aluminum or aluminum-zinc anode rods that wear out over time, Corro-Protec’s titanium powered anode rod delivers reliable long-term protection in soft, hard and softened water. Powered anode rod technology is trusted by corrosion specialists and used in a variety of industries, including pipelines, municipal water networks and more. Corro-Protec helps reduce limescale and sediment buildup caused by hard water minerals, helping keep your water heater cleaner and energy efficient over time. By limiting buildup and scaling inside the tank, it reduces energy loss and supports long-term performance. Average annual water heating energy savings in the United States are US$40 per year. Scale can also contribute to costly problems and repairs in water pipes and heating systems. Air bubbles, cloudy water and sputtering in hot water lines can be signs of corrosion inside your water heater. Corro-Protec stops ongoing corrosion at the source, effectively reducing hydrogen release that can cause air in lines and cloudy hot water. It helps maintain smoother, more consistent hot water flow without bubbles or hissing at the tap. While factory-installed magnesium anodes can produce hydrogen and contribute to the issue, Corro-Protec stops this reaction inside the tank. Say goodbye to water heater anode rod replacement, even in hard or softened water. Because tank manufacturers require anode rod inspection and replacement for continued tank protection and performance, Corro-Protec helps reduce upkeep while supporting long-term energy efficiency and reducing the need for tank flushing by limiting buildup. Water heating accounts for nearly one-fifth of home energy use in the U.S. Corro-Protec helps save an average of US$40 per year in water heating energy costs. This is the standard Corro-Protec model for most water heaters. It fits dedicated anode port installation, which is the setup used by most tanks. The box includes the powered anode rod and power supply for this standard installation. This is our alternative Corro-Protec model for hot water outlet installation. Almost all Bradford White tanks require this installation type. The box includes the powered anode rod, power supply and wye-piece for this setup. Corro-Protec works with all major water heater brands and virtually all water heater types containing an anode rod. Learn why powered anode rods perform well in city and well water, plus water treatment systems such as water softeners. Swipe through the images to discover the 5 key compatibility points, including the 2 model options for dedicated anode port installation (the standard installation) and hot water outlet installation (the alternative installation, standard for Bradford White). Most water heaters use a dedicated anode port, making this the standard Corro-Protec model most people need. It works with major brands such as A.O. Smith (97% of tanks), Rheem (100% of tanks), Whirlpool, GE, State, Ruud & more. Because manufacturers often require anode rod inspection & replacement every 1 to 3 years, this powered anode rod is a simple long-term upgrade for most tanks. Bradford White tanks are the exception, as they usually require hot water outlet installation (see next image). Some water heaters use the hot water outlet instead of a dedicated anode port. This specific Corro-Protec model also includes a wye-piece, is made for that installation & fits almost all Bradford White tanks, plus AO Smith GPCC-40L, GPCC-50X, GUF-40 & HPCX models. The Bradford White models below can use our dedicated anode port model: RE250T6, RE255T6, RE130L6, RE230LN6, RE240LN6, RE250L6, LE255T3-3, LE120L3-3, LE230LN3-3, LE240LN3-3, LE250LN3-3, RE2H50S10-CON, RE2H656T10-CON & RE2280T10-CON. Corro-Protec works with virtually all tank water heaters containing an anode rod, including electric, gas, hybrid, heat pump, solar and geothermal models. As you may have read in your water heater owner’s manual, manufacturers require regular anode inspection and replacement when needed. This includes A.O. Smith (first 6 months, then at least annually), Rheem (annually) and Bradford White (every 2 years). That is why upgrading to a Corro-Protec powered anode rod is a smart long-term solution. Corro-Protec is compatible with all water treatment systems, including water softeners (salt- or phosphate-based), reverse osmosis and whole-house filtration systems. Note that softened water can make sacrificial anodes wear out faster, increasing inspection and replacement frequency. A.O. Smith, Bradford White & Whirlpool mention this directly in their manuals. Corro-Protec is a durable solution for water heaters connected to water softeners, long-term tank protection and sulfur smell removal. Corro-Protec’s powered anode rod performs well in all water types and qualities, including city water, well water, hard water, soft water and softened water. If you want reliable protection across different water qualities & sources, Corro-Protec is designed to perform where magnesium and aluminum anodes wear out. Corro-Protec automatically adjusts its current to provide optimal corrosion protection in all water qualities, including stopping SRB growth, often linked to sulfur smell in hot water. 40 to 89 Gal.

    • It really works!
Size: 40-89 Gallon Tank
I have fought with stinking, smelly hot water for a while now since big outfits came in and started drilling these huge wells and piping millions of gallons of water to sell to cities a hundred miles away and disrupting our once wonderful well water. I had been using chlorine to kill the smell temporarily, but the smell keeps coming back and it's a pain to have to do it on a regular basis, plus I didn't like putting all that chlorine in my drinking water. I looked at chlorination systems that would do it automatically, but the cost was over a $1000-$1500. I had seen this on Amazon but for the price I thought, "Yeah, another snake oil product that's just a waste of money". Boy was I ever wrong! The hardest part of the installation was getting the old anode out. Because of limited clearance the old anode had to be cut in 3 pieces to get it out, but it only took about 10-15 minutes with a sharp hacksaw blade. (Don't use a power saw. Magnesium is easy to ignite and extremely hard to extinguish.) Also, make sure to use a pair of vise grips to hold on to the rod as your cutting it. If you let the cut rod fall down into your water heater it would be just about impossible to get out. Total installation time was less about an hour. I will say my water heater was fairly new, maybe 6 months old, so the old anode came out easily with an impact. I had read that it took about 24 hours to get rid of the smell and that's about what it took. The next day I noticed no smell at all from my hot water. Oh happy day! I am so glad I decided to give the Corro-ProTec powered anode a try. I was ready to spend a ton of money trying to get decent smelling hot water back and here I wound up spending less than $200 to get my water back as good as it ever was with adding any chemicals. Thanks so much Corro-ProTec for such an excellent product. I'll tell everyone who has smelly hot water to not hesitate but buy this now! ... show more

Review Image by Raak
Ok so we moved to a new house with septic and well water, which I have never had before. The previous owner got septic cleaned one day before handing us the house. First day, we noticed a fowl smell in the sink, a friend who has well and septic said it might be coming from septic since they just cleaned it, give it a few days. I did, nothing changed. Then I decided to call a well company to come check the water, now sadly we didn't have a water filter in our basement, just a water softner system. So the well company said smell might be from bacteria in the system, you need filters, reverse osmosis preferably, but if not, at least a nano filter 0.01 microns to filter out the bacteria. Sounded convincing, but from the 2 quotes we got, one was 16,000 for a rolls Royce of water filters, and one was 9000 for the nano, we settled for that and got it done and also got a bigger water softner. They bleached the system before installing so they could kill all bacteria in pipe lines. Took 8 hours, installed everything and went, smell immediately went away, only to return after 2 to 3 days. Can't explain the feeling. I have to admit that when I smelled the water on first day, I googled it and found that hot water heater has sacrificial anode rods and they go bad and I could either replace it with another 30 buck rod, or get titanium which last long and costs 80 bucks OR get corro-protec and I also watched the installation video, so I kind of knew I need to do this but was waiting for a professional to tell me that, which didn't happen. The well company sold me filter and all, and then when smell came back, they said I need a chlorone injector for my filter (another 2500 bucks). I said NO. Because i don't want chlorine in my drinking water if possible. Then I looked for a plumber who could replace my anode rod in water heater with corro-protec. Found one and they said they can come next morning OR a week later, so I quickly searched and found same day delivery on Amazon. So I i gave them a go ahead for next morning. Next morning plumber comes and inspected the smell and said that's not coming from water heater, if you have a well, it's coming from there. (Another expert not telling me to install this). I said to him, I spoke to your company and they sent you here to replace the anode rod and flush my system ($700 BTW), so do it. He said I am trying to save you money, this will not solve your problem. I said I don't want to save money and am not asking your opinion, please replace this if you can, otherwise I'll look for someone else. Can you imagine the dilemma? This is me, with my google research, after spending 9000 dollars on a well water filteration system telling another expert that I want you to charge me the 700 bucks even if it doesn't help. Well he flushed the water heater, took out the anode rod (check the picture of how yuck it looks), and installed corro-protec. It took about an hour for the water to heat up but when I opened the faucets the smell was gone. Zero sulphur smell. I wanted to make sure I wait a few days before I do my happy dance and post this review. It's been over a week and it is working like a charm. It still sucks that no experts recommend this product, but end of the day, here's a reason for us to take so much time to post reviews. I am pretty handy but I didn't want to mess with my 17 year old hot water heater and mess up something big time so decided to use a professional company. Best money spent. Highly recommend this product for those with similar use cases. Good luck ... show more

Size: 40-89 Gallon Tank
Had sulfurous odors in my hot water for several months and was looking for a replacement anode rod when I came across this item by chance. I had never heard of this method before but it sounded like a good idea so I looked into it. Turns out it has been used for years for corrosion protection of steel in the maritime and pipeline industries and has proven to be effective. It has hardly been used at all for domestic hot water tanks probably because it would increase the price by a hundred bucks or so. Plus, plumbers probably hate it since it should last the life of the tank as opposed to anode rod replacement every few years which the average do it yourselfer may not want to tackle. It works using a method called ICCP or impressed current cathode protection. The anode rod made of aluminum or magnesium is standard on almost all hot water tanks and serves to protect the steel tank from the natural corrosion or oxidation of steel in contact with water and oxygen. This happens even in glass lined tanks and with good quality water. The steel (mostly iron) does not naturally have uniform properties at the surface and in contact with water but instead has areas, called anodes, where corrosion (oxidation) takes place when iron atoms lose electrons turning the atoms into iron ions. The electrons remain in the metal but the ions can leave the surface and go into the electrolyte (water). The electrons travel through metal to a different area, or cathode, where they react at the surface with ions to complete an electro-chemical circuit. The important point is that corrosion will not take place if the iron does not lose electrons. The anode rod, say magnesium, does this by providing a surfeit of electrons into the tank iron since the rod and tank are physically and electrically connected. In effect, the magnesium rod is such an effective anode that it makes the entire tank metal a cathode. The result is all oxidation takes place at the magnesium (anode) and none at the tank (cathode). Thus, the magnesium is consumed and has to be replaced periodically and so is called sacrificial by saving the tank. Also, naturally occurring sulfates and sulfur bacteria in well water can react at the magnesium anode and produce hydrogen sulfide gas (bad odor). For the ICCP method, the needed electrons are provided by an external power supply and the anode is an inert material that does not corrode. The electro-chemical path is from power supply negative terminal, to tank (iron), to electrolyte (water), to anode, and back to power supply plus terminal. Note conduction is not by free electrons through the electrolyte but by ionic conduction and thus varies with the ion species and concentration in the water. This is why, for a given current, the voltage at the anode has a wide operating range over different systems. After considering all of this I decided to purchase the Corro-Protec and I'm glad I did. I received it in two days, it was well packaged, and it looked and felt high quality. I removed the magnesium rod which was uniformly pitted and covered with a slimy white material I take to be a form of magnesium oxide. I flushed the tank with plain water until it ran clear and installed the Corr-Protec. I have not had the slightest hot water odor since, at about one month. The Corr-Protec power supply is more than a transformer and rectifier; it also has circuitry that senses output current and holds it constant over a voltage range of 0 to 22 volts. Most power supplies operate at a constant voltage with a variable current dependent on load. In my case, for a 40-80 gallon tank, current is preset for 15 milliamps and the voltage varies between 3.5 and 4.5 volts over several days depending on ionic properties of the water. After a regeneration of my water softener (ion exchange type), the voltage decreases by about 0.3 volts for a day or so presumably due to some residual brine in the softener plumbing. 3/22/2024 update, After nearly four years of constant use, I have not once detected any odors from the hot water and I have not had any problems. So I am 100 percent satisfied with this product. ... show more

    • Powered anode rod? Yes please!
Size: 40-89 Gallon Tank
After a random video on yt about water heaters, I decide to check my own. Yeah, I needed a new one. After searching for a regular anode rod, I came upon a video with the corro-protec. I researched more and more about it and I was sold. I didn’t see any real negatives about it and purchased it the same day. Installation was easy, just follow directions and it should be no problem. I think many people don’t know what an anode rod is and located inside the water heater. I didn’t. I know it needs to be flushed once in a while. I did have to change the thermocouple which died in in the middle of winter. The price is high compared to a normal anode rod but in my opinion worth it. The 20 year warranty is awesome. The thought of possibly of not changing it in 20 years is a bonus. I’ve heard customer service is good also. And to keep my water for a bit longer is good too. All in all this device uses simple science to combat corrosion and smell in a water heaters. It is very useful to a home product which is taken for granted and hardly even thought of. This is an excellent product and should be a good replacement for older water heaters and even newer ones without the worry of changing the original one every 5 to 6 years. I’ve heard people needed to change the replacement earlier. Depends on water conditions and where the water comes from I guess. Okay, that’s it. Highly recommended! ... show more

My daughter’s water stunk. In my research the question I learned to ask is whether it was the hot water that stunk or both the hot and cold. In her case it was just the hot, which indicates a problem with the standard water heater anode corroding and disintegrating and that’s what causes the stink. That’s when I read about the powered anode. All the reviewers loved it, saying the stink went away the next day or quickly basically. That’s the bottom line. It fixed the issue quickly, no expensive water filtration system needed, which is what MANY companies push to fix the issue. I talked to plumbers that had no clue about this product. I highly recommended it if you have a smell issue. Note that I did it myself but I’m very handy, not beginner or average. You need two large sockets and an impact gun. You have to locate the stock anode on the top of the heater and dig down through the insulation between the outer shell and the anode to get to it. ... show more
