Description

Visit the Store 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.

    • works fast and well!!!
Size: 40-89 Gallon Tank
installed this at 6pm on a Wednesday night, by 5:30am the next morning the sulfur smell was completely cone. Very easy to install although I do have a complaint that you have to buy a 1-3/16 deepwell socket which is NOT a standard size in any of my sets of impact sockets and I found it kind of ridiculous since all the other annode rods were 1-1/16 including the one on my tank. Why make everyone buy a special size???? Other than that this works extremely well so far, let's hope it is quality and lasts. ... show more

    • What you need to know before you start installing a Corro-Protec powered anode.
Size: 40-89 Gallon Tank
The Corro-Protec powered anode rod works exactly as it claims. It will immediately remove the "rotten_egg" smell coming from your hot water tank. Mine was pretty terrible after installing a brand new water heater 6 mos. earlier. My well water was reacting with the factory installed magnesium anode. This was causing bacteria to proliferate in the water heater and creating an obnoxious sulfur smell. Within 12 hours of swapping out the anodes the smell was completely gone. This product really works well and is worth everything I spent on it! It also has a 20yr. Warranty!! Very nice. There are some really big cons if you want to do it yourself, as I did. First problem was getting the existing anode out. It can be very challenging. It takes a special 1-1/16" 6-point socket to extract the factory installed anode. I couldn't budge it beating on my 1/2" breaker bar to loosen it. I had to finally put my 1/2" impact driver to use to get it to free up. Note: impact sockets wont fit in the anode recess. It has to be a thin wall socket. 2nd issue is extracting the anode from the tank. I did not have enough ceiling room to fully remove the factory anode. I literally had to cut it and remove as 2 pieces. I used a powered hacksaw and it took 10 minutes to do so. The last issue could be that you may need to get 110v power closer to where your tank is located. This unit has to remain plugged in to function. If you have the proper equipment needed that I mentioned above you can save a considerable amount of money in this doing yourself. My cost $185.00 Quoted price by plumber $500.00 ... show more

It clearly states in the ad that you will need a 1-3/16 socket to install this, no it does not come with it. I did not have any luck with local hardware stores so had to buy it online. This rod works wonders. In 24 hours my hot water went from from scrambled egg wet fart to fresh and clean smelling water. Install was super easy. Make sure you also have a 1-1/16 socket to remove old rod and maybe a torque gun to remove. Do not use torque gun to install new anode. ... show more

    • Took care of hot water odor.
Size: 40-89 Gallon Tank
The odor in the hot water (on a well) started showing up this year on a 6 year old water heater. It's been a month since installed and the odor from the hot water hasn't returned. It was easy to install. I used a 1 1/16 socket with impact to remove the old one. The new rode will take a 1 3/16 socket, but if you don't have one and since the rod's head sticks up from the heater you can probably use a cresson or pipe wrench to put it in. My old anode rod was 6 years old, and still had plenty of metal left on it, however it was corroded a lot, so my old rode was probably not working anymore. A new normal rode might have also corrected the problem, but I chose to use a powered one, so will see if it holds up long term. ... 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

Like the idea of this product. I was about 3.5 years in on my current 50 gallon water heater and figured I was approaching the time for a replacement given the mineral content of our town's water. Decided to try Corro-Protec versus another standard anode rod as I did not want to have to revisit this again (and again and maybe even again); this system allegedly will last for 20 years (or more). I don't have the "rotten egg smell" to contend with, so cannot speak to it's effectiveness on that front, but there are other advertised benefits, like reduced sediment accumulation and a reduction in lime scale, which I found appealing despite the lofty price tag. Regarding installation, the process was pretty straightforward. Checkout YouTube for some good step by step guides. One piece of advice would be to use/borrow an impact wrench versus using a socket wrench (and cheater/breaker bar); this made taking the old anode rod out pretty simple. [Do recommend finding a deep socket as there is a metal tab that juts out of the top of the Corro-Protec, which is where the AC adapter hooks on. I had a shallow socket and did end up bending the tab, but was able to reposition it (thankfully) without issue.] My only criticisms at this stage would be the exclusion of teflon tape in the kit (like c'mon... it's $150+ and can't spare a few feet of tape?) and, out of the box, the rod was a bit bent to one side. It was easily repositioned by hand, but the box was in perfect condition, so not sure how this happened to the product. Also, despite the company's highly (self)touted warranty, I'm not overly impressed with the terms. The consumer is still inheriting a lot of risk and needs to have blind faith in the product doing what it's billed to do. If your water heater corrodes and gives out with this anode installed, they will not cover anything. Corro-Protec only covers the anode/power supply. Certainly, if other components of the water heater fail, I wouldn't expect that to be covered, but even if the anode fails in it's primary purpose and the tank does corrode, the company still claims no responsibility. Additionally, full reimbursement is only offered for the first 5 years, not 20. After the 5th year, coverage decreases 5% each year. (e.g. at year 20, you'd only have 25% coverage) Lastly, on a related note, there are anecdotal accounts of water heater manufacturers not honoring their warranties when this unit is installed. This might vary from company to company, but better to assume your tank warranty is void if you use this product. (It better work!) All that aside, I'm still focusing on the positive. I'll be interested to see if I notice any changes to the water heater performance or water quality, but suspect that they will be subtle. Will update this review accordingly. 3/27/24 UPDATE: I definitely noticed a lot less lime scale in the dishwasher almost immediately. This effect has persisted in the 5 weeks since installation. So far, everything still seems to be working well and the bright green light on the power supply is on. Nice product! 8/30/24 UPDATE: All is still well. Scale levels still seem to be reduced. Looks like a good product! ... 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

    • Simple to install, 100% Effective in Sulfur Smell Removal
Size: 10-39 Gallon Tank
Not one to write reviews but felt compelled to do so for this item. We recently had to have a new well dug on our property and since doing so have had that awful suffer smell in our water but only on the hot "side" of the plumbing. Our water heater was less than a year old so I figured couldn't be the issue. Once I read about this product I thought it certainly was worth a try. It most definitely required an impact driver to remove the existing anode even as "young" as it was. Installation was simple but not real simple, but to no fault of the Corro-Protec. I actually had to use tin snips to cut away a small portion of the metal around the access hole to the anode as I could not get the socket on the head of the anode due to the thickness of the socket, and the positioning of the access hole. But that only added a couple of minutes to the process. Total installation, including removal of the existing anode took less than 15 minutes. Once installed and running, the sulfur smell was 80-90% removed from the hot water within about 5 hours. Within 24 hours NO SMELL AT ALL. This device is practically a miracle product. I woe recommend it 100% if you are experiencing sulfur smelling hot water! ... show more
