    We just bought an older home (built in 76) and the water smelled awful! After you ran it for a few minutes it turned black. It’s city water so it wasn’t a well issue. After some research we decided we needed to replace the anode rod and flush the water heater, which looked brand new. We did this and put the Corro-Protec rod in and haven’t had a problem since. It took about a day for me to not notice the smell anymore. I’m not sure if there was some existing sediment or whatnot that needed to be flushed away, but this thing is amazing!!! Immediately improved the odor to barely noticeable! I should mention that. So glad we bought it. Highly recommend!!!

  2. Schlabow

    Great product.!!! Got rid of the rotten egg smell in my water.

  3. Joey

    Only 24hrs after the install and I would say 99% of my water smell is gone. I would contribute the 1% to just being well water but, the rotten egg smell is gone. I aluminum and magnesium rods with no positive result as my hot water would smell up the entire house with one shower. This is well worth the investment. I highly recommend.

    I am now closing in on two months and it is still working great. Being well water there is always a little smell as compared to city water but I would say it is well worth the investment. There is no more rotten egg smell. I saw numerous claims online going for way more and saw this on a forum. No retreats, is truly a great product.

  4. Flydunker

    install is not easy, but it doesn’t have anything to do with the product, the old anode is extremely difficult to get out and is covered in 4″ of foam insulation, I had the tools and I got it installed, but took an hour. ONLY issue is no one knows if it works, till the water heater gets eaten up, or survives for years of service.. So, that said, the sulfur smell went away, but it would have if I had just removed the anode and plugged the hole. SO>.. We’ll have to wait and see.

  5. D ledbetter

    we were doubtful but desperate that this would fix our stinky hot water smell. It fixed it!!!! we are so excited. worth every penny and quick delivery.

  6. Brian

    This thing works amazingly! Sulfer smell from hot water gone instantly. If you have a well and just your hot has a sulfer smell, this is the solution! To the people that say it did not work: I believe your old anode corroded into pieces and there is still chunks of it down at the bottom reacting with the water. I just installed a brand new heater, water had only been in it for a week and it was already showing signs of erosion. This is a great product at a good price. Get it.

  7. Laura M

    It was easy ton install and corrected the sulfur (egg smell) issue.

  8. Gregory M. Richard

    Rotten egg odor completely gone. The hardest part about the installation was getting the old anode out of the water heater. New device looks well built. The real test will be to see how long the water heater lasts with this new anode in place.

  9. Britt

    Very easy to install. Took about 10 minutes. Hot water stopped smelling bad almost immediately. Would definitely recommend.

  10. Shaun M

    Worked great ! Smell is gone !!

  11. Radarthebadass

    It’s been installed for a month now and after the first couple days the sulfur smell is completely gone from my hot water.

  12. Gary

    I’m pretty critical of snake oil cures given that I’ve gone through 4 anode rods in the last 3 years since I bought a new house, on a well with softened water. The aluminum anode worked best but crapped out in a year while the magnesium rod lasted but gave the awful smell. The reason I went with this unit was that I didn’t have to keep the water heater on high to help kill off the odor. Or so I hope. I just installed this today as my water was starting to smell like sulfur in the shower after a new rod change plus peroxide treatment a month ago. I did nothing but install the new one which literally took 10 minutes. 4 hours later the smell is all but gone. The electrical setup on this looks beyond cheap but there’s next to no power being sent through it so only time will tell. I’ll come back to give an update whether or not it killed off all the odors or if the unit gives out. In just a few hours I’d have to say I’m very impressed.

  13. TMH

    What an amazing difference. I installed this device last weekend at our farm house. My wife and I took smelly showers for well over a year at the new farm house we built in 2016. SSL Family Dad on YouTube was the source of me learning about this device. He was 100% correct. I installed the Corro-Protec in the morning. That same day in the evening my wife and I showered. No more smelly H20! The hot water in our house is now odorless! Before this device it was stinky rotten egg smelling. I just hope this device lasts a long time.

    A couple of suggestions to pass on: 1. when you remove your anode rod to install the Corro-Potec, make sure you have a long ratchet or a pipe to add to the ratchet to give yourself leverage. My anode was so tight as I was attempting to remove it, it was moving the water heater (approx 35 gallons still remained in the water heater). I had to brace it with my body and really pull with my ratchet with extension (steel pipe) to remove my anode rod. 2. You do not need the big socket to install the Corro -Protec. You only need a big crescent wrench. 3. Make sure you wrap the Corro-Protec threads well with Teflon Tape.

  14. Colby

    Works great if you are in well water that has hydrogen sulfide in it. Very smelly water! Take the aluminum rod out and put this one in. Plug it in and it works great. No more rotten egg smell.

  15. Amazon Customer

    It actually works like they said and fairly easy to install.

  16. Cherise Delbuno

    Was kinda sceptic at first , but love it ! No more stinky water from hot water heaters yay !!!!! And saved a lot not having to replace them.

  17. Dennis Jolicoeur

    I was very pleased with this Product. It’s a little more expensive then just replacing an anode rod. But I think it works much better.

  18. KMF

    Works great!

  19. Richard Lauby

    Needed to get rid of the rotten egg smell. Heads up on getting the old anode out. tried a 4 foot breaker bar with me trying to hold the tank and the other person on the breaker bar. no luck. finally bought some Kroil penetrating oil and let that oil sit on the anode fitting and when i tried it the next day it came right out without any breaker bar or anything other than socket and driver. moral of the story. get the best penetrating oil. forget pb blaster and wd 40. get kroil or something as good and it will make an impossible job easy. great result to have odor free hot water.

  20. Maureen Goeman

    We recently bought a lake house with well water. During the sale, the water was inspected by the county and was found to be very acceptable. However, the “rotten egg smell” at the faucet was enough to make one gag. I just installed this device on my water heater and the results exceeded my wildest expectations. After refilling the tank for the first time, the smell is completely gone! I’m a 62 year old do it yourselfer and I told my wife that this project was the best project that I have ever done. Buy this if you have smelly water!

  21. Slack L.

    We have well water in our mountain vacation home in Pennsylvania. The water is very high in iron content that we control with a Culligan system, but the rotten egg smell was impossible to get rid of until we found this product. My husband installed it in our water heater over 18 months ago. It cleared the smell instantly and continues to work as promised. Best purchase I’ve ever made and worth every penny.

  22. D Squared

    Eliminated the hydrogen sulfide smell in our hot water tank within 12 hours. We are on well water and have an iron-sulfur filter followed by a water softener. However, due to the magnesium anode in our hot water tank the sulfur smell persisted. We installed a new hot water tank with the Corro-Protec anode 4 weeks ago. It also eliminated black residue in the hot water from the old tank/anode breaking down due to age.

  23. Amazon Customer

    The product is expensive but seems to work well so far. The installation required a bit more work since I had to buy a large socket and also had to cut the tin at the top of the water tank for me to install and tighten the anode.

  24. Kim Lawrence

    This product worked great. It was easy to install.

  25. Calsmart

    Please be aware that the manufacturers of water heaters will void heater warranty of any modification including installation of Correo Protec on the heater. Bradford White heaters will require installing bypass T connectors to be able to install this product.

  26. Freddie M Pekar

    I have had several plumbers attempt to get rid of rotten egg smell from our new, less than a year old hot water heater. Flushed it out with Clorox several times 2 days later rotten egg smell came right back.
    I saw this on Amazon.com I gave it a try. thank god I did it has been over a month no smell anymore. great product easy to install.

  27. Amazon Customer

    Our hot water smelled like rotten eggs. After installing this device, the smell vanished.

  28. Patti

    Absolutely fantastic product! No water smell since we installed it about a month ago!

  29. Magicflute

    For the past ten years, we have been plagued with a strong sulfur smell from our water heater. There was an aluminum anode rod in the heater and, from what I’ve read, that was probably the problem along with having well water. I had the powered anode rod installed a little more than a week ago and the change was immediate. The heater was flushed and that might explain the lack of smell in the beginning, but the smell has not yet returned. Not only has the lack of smell been noticeable, but the feel of the water is also different. We have a water softener, and the water now is, to quote Goldilocks, not too hard or too soft but just right. My wife took a drink, the other day, and she said that the water tasted great.
    So, the bottom line is: a little expensive, yes, but certainly worth it considering the problem that it solved, and that the anode rod will outlive me.

  30. Beverly Telepchak

    Easy to install. Arrived before estimated delivery date.

  31. Amazon Customer

    Did not fit in my water heater! Threads were not long enough & wouldn’t seat in heater . Not compatible & no invoice for return. By the time I tried to install & found out, missed my window for returning $110 worth of unhappiness!

  32. George P Raneri

    I bought this for the water heater at my mom’s house, as she was complaining of stinky water. The original magnesium rod didn’t cut it, and the replacement zinc/aluminum rod (which everyone said would fix it) didn’t help either (quite the opposite in fact)!

    A bit skeptical, I decided to take a chance on this powered anode rod for the smell, and to my incredible surprise, it worked! As an aside, I will say that while I had it opened, I did add about 1/2 cup of peroxide, as it was also recommended as a solution for the stink, but it was agreed that peroxide alone would only work for a couple of months at best, and I had only used 1/2 the recommended amount since it was all I had available when I did the repair.

    It’s nice to be able to go visit and not worry about the house smelling like a post Taco Bell fart fest every time someone washes dishes after a meal (or washes their hands, takes a shower, etc.).

    I don’t know exactly how it works, or for how long the short anode will last, but I do know that the smell is gone because of this!

  33. Tom

    After following all of the instructions for installation, the green light on the rectifier was not on. But then the company sent me a new rectifier immediately, and it is working fine now.

    It is important to remember that in order to stop the rotten egg smell, you must do two things, not just one. You have to replace the old anode with the corro-protec product, AND you have to clean your system with chlorine. (Culligan did a great job on this for us.) The rotten egg smell is NOT coming back. You cannot just install the new anode and expect it to go away. It is embedded in your pipes. The new corro-protec is NOT producing a new generation of the sulfide gas. So it was a complete success.

    something must be wrong, so now I will have to get help from the manufacturer. I hope they are responsive.

  34. T. Stockman

    My well water has one of the bacteria strains that interact with normal standard anode rods, installing this rod made a significant difference within a day & an apparent complete cure within 2 days. It’s certainly possible an upgrade to a better non-powered rod would have done it, but this looked like more assurance of a cure, plus better long-term corrosion protection. Been in place 6 weeks and all is well.

  35. Edward Sansom

    Placed it in the hot water heater and it works great.

  36. Donal Crowell

    Not sure yet the end results. Just installed today. installation was very easy.

  37. Ralph

    This product is the real deal!!! It eliminated 100% of the sulfer/rotten egg smell from my hot water tank. Here is a breakdown of my situation:
    1. Water comes from a very clean, low mineral well.
    2. A salt based water softener/condition system is in place.
    3. Water tank is a Rheem 40 gallon, Classic Professional Series
    4. Cold water is odorless and tastes great, even without the softener system involved.
    5. Hot water had a very strong rotten egg/sulfer smell. HAD. No more. Within an hour of installing the Corro-Protec CP-R, my hot water had NO smell at all.

    Now, the not so great part of the story. It was a royal pain in the kiester to get the old anode rod out of the tank. Once the top of the rod was exposed, I tried a 25 in. breaker bar on the socket (two pretty hefty, strong fellas leaning on it). And, I tried a pneumatic impact gun with 175 p.s.i. of pressure. Neither broke it loose. Finally, I added a 4 ft piece of pipe to the end of the breaker bar and it finally popped. From there, it was easy going. I did have to cut my existing anode rod to remove. No big deal. Just remember to put vice grips on the rod BELOW where you cut so the lower piece doesn’t fall back into the tank. Follow the directions with the Corro-Protec CP-R and enjoy your first non-stinky shower.

  38. Amy

    Easy to install. Instant results. Sulfur smell in our water disappeared in minutes after completing installation and a short flush of lines. Corro-Protec has been in service for a month and we’ve not detected any odor since.

  39. Thomas R.

    The hardest part about installing this was getting the old one out. I bought a new water heater to replace a very old tank that went out. About 2 weeks after installing the new tank my hot water started smelling really bad and turning red. It got to the point that I smelled worse after my shower than before. To get the old rod out I had to buy an impact wrench. When I checked to make sure that I had a socket to install the new one I found out it was larger that anything in my tool collection. I went out and bought a 1 3/8 wrench so I could install this, thinking it would be counter sunk into the tank like the old rod. Turns out I did have to have the new socket because this sits slightly higher than the top of the tank and could of been installed with an adjustable wrench.

    After removing the old rod I flushed the tank, added 4 gallons of vinegar. Then installed the new rod and filled the tank and flushed the hot lines until I smelled the vinegar. I let the mix sit over night and then ran the hot water out of all the sinks and showers until no more smell.

    Months later as I write this review I have not had any order problems with my well water.

  40. Steve Michigan

    Installation was pretty straight forward for my 40 gal Rheem electric water heater. My water heater is relatively new, so removing the old anode rod was not too difficult. If you let the water heater cool down enough where the anode enters the tank, it will be easier to remove. Heat expands both the inlet threads and the anode rod threads locking them together besides the torque when installed. I treated the tank with H2O2 while I had the anode removed. It has been only 1 week since the changeover. Rotten egg smell is non-existent today, but that could be the result of the peroxide cleanse. I will update this review as time progresses.

  41. Paul McGinn

    We had smelly water at our cabin. The powered anode solved the problem. I previously tried an Aluminum / Zinc Flexible Anode Rod (https://www.amazon.com/gp/product/B00M4S7Y5A/) but that didn’t do the trick. The powered anode works like a champ. As others have noted, the most challenging part will be removing the factory anode. I had already fought (and won!) that battle installing the Al/Zn rod, so dropping in the powered rod was a piece of cake.

  42. Tracie A. KOBOSKI

    This worked!! I can take a shower without plugging my nose. I would even drink the water…. thanks!!

  43. Donald

    installed a year ago and solved the foul sulfur odor from my water heater / hot water; seems to be performing well.

  44. Sam

    Working like a charm! Wish there was a better way to know how to torque it in. Old one was a bear to remove.

  45. Kamazon

    We bought this to replace a regular anode rod. We have well water which runs through a softener system and it created a rotton egg smell when going through the heater. After a few months of this being installed, I’m happy to report that we have had no more problems with smelly hot water. This was very easy to install but I would say the hardest part would be to remove the old anode rod. I suggest strapping the water heater to something that we’ll keep it from turning and using a metal rod or cheater bar to loosen the old rod. If it still doesn’t budge, I used a little bit of cola to loosen it up.

  46. John J.

    This completely eliminated the sulfur water – rotten egg smell from my hot water. Works from the time it is installed. Never regret this purchase.

  47. DML

    I tried many other routes for ending sulfur smell in hot water. Two months after installation and no bad odor in the water. Great product.

  48. Amazon Customer

    We have a beach house and the water had a very strong sulfur smell. Every time we visited the house I would drain the water heater to try and mitigate the overwhelming sulfur smell. I installed the Corro-Protec CP-R Titanium Powered Anode Rod and the sulfur smell was completely eliminated. It is very simple to install once you are able to remove the existing anode rod from the water heater. The existing rod was a bear to remove, I used a 3/4″ cast iron 12″ pipe to supply leverage to my ratchet. I picked up the pipe at Home Depot for about $5. This product worked a miracle.

  49. S. Lampe

    Not sure that it is even working anymore. Seemed like it was helping for the first couple months as an addition to the original anode rod, however after about 6 months installed along side regular anode rod it no longer is effective. Replace original anode rod and sulfer smell subsided for now.

  50. Oh Gosh

    Used some hot water about 2 hours after installation and the smell was gone. Now, 3 days later, and the bad smell is still gone.

  51. Amazon Customer

    I don’t usually leave reviews but this thing is awesome. After a long battle with stinky water, this powdered rod completely fixed the issue almost immediately. Tried the aluminum/zinc rods and shock treatments without much success, I wish I would have just bought one of these from the beginning.

  52. S.G

    it stopped the water odors from the water heater.

  53. CEP

    We have well water, with a softening system, combined with a brand new water heater. Needless to say, the egg smell was awful. It was to the point that I didn’t want to shower anymore lol. Upon looking at the device, it looks like some sort of junk, as seen on TV, product. Truth is, it’s a miracle in a box! The biggest problem was getting to old anode out. I ended up having to use an impact wrench, which I highly recommend. It’ll save you time and frustration. Also, be sure you vacuum out any insulation debris before installing the new rod. Also, on a side note, when buying a new water heater, turn up the temperature on the thermostats. It comes set at 120 degrees from the factory. That low temperature will save you a little bit in energy costs, but will also cause bacteria to grow and thrive in you tank. Then you inhale it when showering. That leads to the possibility of legionaries disease. 140 degrees for my thermostats. Kills the bacteria instantly and it only costs 8% more over the course of a year. Your lungs will thank you. I learned the hard way with me and another family member getting bad respiratory infections, POSSIBLY due to the water, but cannot be confirmed. Better safe than sorry.

  54. Just one guy

    Works great.

  55. Amazon Customer

    I had stinky water in Ohio. This was the answer and it works perfect. You may need some help and a 3 foot galvanized pipe to get the old rod out. IT WORKS!!!!!!

  56. John T

    I liked the easy installation. The old anode was very hard to remove.

  57. Fetacheta

    We live in a smaller town outside of Austin that is growing rapidly. We have a new home and in the first year the entire neighborhood had complaints of sulfur like smells from the water. We have a water softener as well. Apparently, the city was having some issue but it wasn’t getting resolved. Bought this little guy put it in and flushed the water from the house – voila we could shower again. Yes, it was so bad we could not shower…for a week.

  58. Jonathan Weber

    Bought a house with a well three years ago and would get terrible rotten egg smelling hot water every 3 months or so. Flushing the hot water tank out would get rid of the smell for awhile but it would always come back. Had the water tested twice but never received a report of contaminates that was of concern. I had to fight to get the old anode out but installing the powered anode was easy. 4 months later and the family is happy that our morning showers don’t smell any more. By the way I installed it in a 80 gallon tank.

  59. PDQ

    We’re on well water, and for years, we would intermittently get a faint rotten egg smell in the shower and elsewhere, usually at the corner seasons (spring/fall). But this year it was stronger and stayed. Yuck.

    After asking advice, I shocked the well with bleach exactly per instructions on my state’s website. It knocked down the smell, but not completely, and it was soon back. When I asked our water softener vendor (a Kinetico), they said have you checked your water heater anode. Anode? P”sha, I said, it’s a natural gas, not electric. Besides’ it’s only 5 years old. But after more smell, and educating myself with some more research, including these reviews, I learned my heater DID have an anode, and was willing to try anything at that point.

    So I took a deep breath and bought this powered anode. The first photo is the anode that came out – wow! That’s after 5 years, and the anode stunk too. I followed the instructions here, including a peroxide treatment of the hot water tank, and oh my gosh, it worked! No smell at all any more.

    That was 3 weeks ago, and no return of the stink yet. Keeping my fingers crossed, but very happy so far.

    One tip- I bought a 1-3/16″ socket (off eBay for ~$10.50 as suggested by the instructions), but didn’t need it. The powered anode (which you can see in the second photo, attached to on wire end) sticks far enough out of the water heater you gan just use a large open-jawed wrench or big pliers to crank it in (and as the instructions say, it doesn’t need too be that tight). You DO need a 1-1/16″ socket to get the old anode out, and if it was like mine, you’ll need an extender on your socket wrench to get enough leverage (I used a thick-walled PVC pipe I had laying around).

  60. Patrick

    This is the second titanium rod I have purchased…so I’ve installed these on two different water heaters with the same result. It’s a pain to remove the old anode rods, especially if they are rusted in, or if the water heater isn’t strapped (you don’t want it to break your piping if it spins/turns). You’ll also need enough clearance at the top to pull the old rod out…so good luck with that. The only con…is that all the old anode rods are a 1 and 1/16 socket…but these titatium ones use a 1 and 3/8 size (most stores don’t carry that socket). Also you might have to make the hole(where the old rod goes in) bigger just to get the socket in for the new one. I attached a pic. Lastly, I had high iron content in my water originally…which left rust/iron in the piping and water heaters even after I installed a whole house water filtration system. So…my advice is to drain and flush the water heater prior to doing the rod change (turn off the power so you don’t burn out your elements), and pour some hydrogen peroxide in you water heater and drains throughout the house. Then fill up with fresh water after installing the new rod, and there will no longer be a chemical reaction with iron or magnesium or aluminum (old rods are magnesium or aluminum). Problem solved! if you had or have high iron in your water, this will work, thus won’t help with soft water/hard water/other issues.

  61. Wyoming

    Great product. Immediately eliminated the rotten egg smell from my water heater. Be prepared to beat the crap out of your old anode to get it removed. Mine was only in a few months and it was extremely difficult to remove. Had to use a 4’ breaker bar.

  62. Green Jeans

    As mentioned before, the toughest thing was getting the old anode removed. Installation was easy and noticed the elimination of the sulfur smell almost immediately. Love the green indicator light on the transformer when plugged in.

  63. G. Meredith

    We have an 80 gallon hybrid hot water tank using well water with a water softening system. Installing this powered anode cleared up the disgusting rotten egg smell in the hot water almost immediately. A few additional points on the installation, in addition to thosed covered in other reviews: The original anode in our tank was over 3 feet long, so it had to be cut to get it out even though we had quite a bit of headroom over the tank. To the list of required tools, I would add a hacksaw, and vice grips to hold the lower part of the old anode while it’s being cut so it doesn’t fall back into the tank. In addition, I needed long needle nose piers to pull the old anode out of its housing. Finally, the 1 3/8 inch socket may be hard to find at big box stores, especially with a 1/2″ drive. I eventually found one at an auto parts store with a 3/4″ drive and had to buy an adaptor to fit my 1/2″ wrench.

  64. Dawn M. Jamison

    I bought this due to hot water smelling like rotten eggs. I was a little skeptical and afraid of the cost. We had already replaced the anode rod. But after a month the smell came back. But with the electric rod after 2.5 months still NO SMELL. yeah.

  65. Susan

    We recently moved to Wyoming and our well water is pretty awful. After replacing our pressure tank, fittings, pump and control box last fall, our water heater than failed. We installed the new water heater and in just a few days got a very strong very repulsive rotten egg smell we had not had before the new water heater. Found this while researching online. Now the shower and laundry DON’T smell like rotten eggs!! The anode from the new water heater was already totally corroded. (no we don’t drink the water.)

  66. Malcamar

    I switched from a chlorine well treatment system to a peroxide one a few years ago. I started to have a problem with rotten egg smelling water. I read about adding a contact tank, adding more filtration and even spraying water back down the well. I was almost convinced about spraying water back down the well when I came up to a video about this anode rod and looked into it. The problem I was having was only when using the hot water. This anode takes care of that by replacing the magnesium anode that came with the heater. I had to order the two sockets and I already had a breaker bar. I did need the breaker bar to remove the old anode and had to remove it carefully as the push from the breaker bar kept trying to rotate the heater. I found that quick, jerky pushes on the bar loosened the anode with minimal twisting of the tank. I did have to push the tank back to its original position a few times until the anode started to come out without much pressure on the bar. The original anode was long so I had to cut it in order to remove it. I used a vise grip to hold on to the bottom piece and prevent it from falling into the tank. A little bit of teflon tape around the threads of the new anode was all that was needed. I also used the socket to drive it in but only hand tightened the anode. The top of the anode is plastic and I was avoiding breaking it like another buyer mentioned in his post. I did not add peroxide or chlorine to the tank before putting the new anode in. I wanted to see if this step was totally necessary as some have suggested. I plugged the unit in and took one last stinky shower. The last bit of rotten egg smell disappeared the next day. I did have to run the water on all faucets and the other shower but there is no more smell. This little device took care of it. The new anode sticks out above the tank and the old anode was buried under a few inches of insulating foam. I did have to cut and scrape the insulation out and vacuum it before attempting to remove the old anode. The whole process took about 45 minutes from start to finish.

  67. Ted Chavez

    I read reviews and almost purchased a zinc rod for my water heater but fortunately for me, Menards did not have any. A little background: I have very hard well water. I have a duel tank Kinetico water softener with a filter in front of the softener. The rust is ridiculous in my system. We decided to replace our water heater as it passed the 25-year mark. After the replacement, we had a horrible rotten egg smell from the hot water side. It literally stunk up the whole house. We did two things to combat this issue. We turned up the water heater to really hot which was one suggestion to combat the bacteria and we replace the rod with the Corro-Protect CP-R. The install was super easy and the results were immediate. The smell is gone, completely gone. I am a bit shocked that it worked so well. That is my story and I am sticking to it.

    Three weeks later and still no rotten egg smell at all. I turned the hot water heater back down to low.

    The unit seems to work well. It almost immediately stopped the smell and the smell has not returned.
    One note for installation. DO NOT use the plastic nut to tighten this into the hot water heater. The plastic nut is bolted into a steel sleeve with a hex on top of it. Use an adjustable wrench to tighten the unit using the steel sleeve. It will save a lot of headache. The other thing I did was put both pipe tape and pipe dope on the threads when I installed it.

    Easy to install, just make sure you read directions. Installed on a Rheem 40 gallon tank. Need a 1 1/16 and 1 3/8 socket. Hardest part was waiting for tank to drain and then refill after installation. Took less than 1 1/2 hours for complete job. So far, no odor to the water.

    Smell from my water is completely gone after just a few days of use.
