Works as advertised, no odor whatsoever for 3 months. Brian.

Purchased in May 2014. Last week hubby noticed the green light was off, plugged in, green light stayed off but the red light flickerer on when I plugged it in. Contacted seller. New power plug came 2 days later and all is well now. I figured they would be out of busness by now but not and i am shocked they sent us another replacement. Never had this type of customer experiance 7 years after my purchase from anyone, never. Thank you very much Matt

Very happy, worked for our home.

This product rocks and so does the seller! Crap water smell, waisted money on other amazon crap. No problems since installed 3 months ago. Thanks Matt! Kim and Erin :)

I own a plumbing company and install close to 30 water tanks a month. I have recently used this product for customers complaining of hot water odor smells. I have purchased close to 50 units since march 2021. I have a better customer base because of this product and now buy from this site for the volume discount. I would recommend this product.

Thanks for getting back to us so quickly Matt. Our heater is up and running again, and the install of your product was a piece of cake. I had anticipated the old anode would be depleted (tank is 2 years 4 months old and we have softened water) but found it was only partially so. That makes me feel very hopeful that we will get extra years out of it now that your product is "in charge" of the tank. Again, thanks for your impressively responsive, timely replies. Never before have I felt so complimentary towards someone who has got me in hot water!

Have a bountifully blessed week.

I am a retired engineer from GM in the electronics division. I purchased 2 systems from Amazon that had great reviews. 1.2Vdc and .05Vdc were the readings to the anode current after 2 months. 3 months later the power unit went out on one unit, the other was .2Vdc. When I removed the anode, the black coating was flaking off. No chemical eching was noticed on the rod which told me this is a very cheap product.

I purchased the water tank tec system 3 months ago for both of my tanks. Each tank is an A.O. Smith short 50 gallon unit. Each week I tested both tanks. #1 2.43Vdc and #2 2.47Vdc consistant voltage on each tank.

This product performs as described.

Our situation. Our home has well water and chews through anode rods every 4 months. In the month of October 2020, we found corro protect on Amazon and purchased it. The odor was gone 2 days later and we were very pleased. I will never forget the time, on December 24th my husband noticed the power supply was flikering of and on. We called the seller water connection who sold the item to us on Amazon. We were told to contact corro protec. We called their 800 number and were told it was out of warranty for a return but they sent us another led box. It faild 2 weeks later with no light this time. I asked for a money back and was told it was beyond the return window. My husband said we are going back to the anode rod.

I contacted water tank tec on Amazon and after several emails, decided to buy this companies product which was a lot less than the corro protect product. I can say as of this review April 24. 2021 I and hubby are very pleased.

I will mention 2 things, great customer service by water tank tec, terible with corro protect and amazon. We tried to leave a review on amazon which is the site we purchased water tank tec from but it was never posted.

I will leave you this reveiew since we along with Janet your other customer could not leave a review on amazon. Here is our story. My hubby and I just moved into our home after a 8 month build. We noticed our hot was had a very strong odor. Our salesman told us it was normal for well water. After some research we decided to purchase the Corro Protec system for both our heaters in February of this year. About a month later our well expansion tank developed a leak which was a simple fix however the water heaters were hot on the outside. My Husband found out both electric anodes were leaking from the top. Since our home has a warranty for 1 year, we contacted our salesman. We found out that since we added this part, they would not cover it. We contacted Corro Protec 3 times and never received a response. We contacted Amazon and was told it was a seller fullfilled item and their was nothing they can do. We had to purchase 2 new tanks and the odor was just as bad as the start.

In March we read your website and felt confident about a purchase. My hubby was able to install both units with help from our neighbor. To this date we have no leaks and our water has no odor. I do want to mention that hubby did drop one of the power supplies durng the installation and cracked the corner of it but it still worked. I contaced Matt asking him if it was OK and he sent us a new power supply the next day at no cost.

I would have never thought in a million years he would do this for us since it was our fault, you just dont get this type of service these days. My hubby and I recomend this product for anyone wanting a well built systems with AWESOME customer service! Thanks you so much Matt!!!

I just wanted to say thank you very much for answering our questions and your timely responses. We are very pleased with your product sinces its installation and have recomended your product as well to our freinds. I am leaving this review with you to post since Amazon will not post my review on your site. I left it over a month ago and it still has not appeared. I have told others about this as well. Thank you Matt for the customer service, I have never had such one on one with a seller before. May you prosper, Janet

I upsell this product to my customers. I have never had a complaint.

Works as described. The odor was gone in 24 hours and that was 3 years ago from our initial Purchase. We bought 2 more systems for our new home. Flushed the tank of our initial purchase last week and no rust colored water was seen. This product works!

Hi. I got your replacement power supply to and just want to say how refreshing it is to deal with a company that honor's its warranty with zero hassle. The green light had apparently failed but you said it was still working and it was just a defective LED. Using A voltmeter, I confirmed it was still providing around 2 volts to the andode and you were indeed correct.

Thank-you once again for your excellent customer support with no hassle. You even shipped it to me in Canada with no charge for the shipping.

I purchased a second system for a friend of mine. I flush the tank every year as Matt recommended, no issues at all.

I purchased another product on Amazon that had a 20 year warranty, it lasted 2 months and the water turned black.. I pulled it out and put in a lowes aluminum rod. I found this website and purchased the product although skeptical. It works as described, odor free for 2 months with no black specs in my water.

I have several rental properties, this product does work.

I purchased 2 units for my home in October 2019. Our water is very corrosive in Michigan and I was tired of replacing tanks every 3 years. It took me several weeks to decide on which product to purchase since there are a several makes and brands out there. I decided to email Matt a few questions. He emailed me back within 4 hours! I decided to purchase the water tank tec product. The instructions were easy to understand and both units were installed within 1 hour and working as described. It should be noted that you should flush your tank before installing this product as the instructions state. I had chunks of black crap come out of my heater for 5 minutes before it cleared up and the tank was only 4 months old. Within 1 week one unit failed and I was upset figuring I purchased a snake oil product. I emailed Matt and learned that my GFCI breaker was bad on one of the power supplies I have, not the product. Last week (January 3rd) I went ahead and flushed the tank again just out of curiosity. The water was clear. I am impressed with this system and for the money I feel it was well worth it. I would recommend this product to anyone.

Received my powered anode and after I installed it, there was nothing but smiles. Finally, no rotten egg smell. Thanks for a product that works! James

I learned that municipal water tanks last so much longer than domestic water heater tanks because they use Impressed Current Cathodic Protection (ICCP) rather than sacrificial anode rods. If our water heater had ICCP, I would not have to remove, inspect, and eventually replace the sacrificial anode rod in our expensive Rheem Professional Prestige Hybrid Electric Water heater. I searched for ICCP designed for deomestic water ehaters and found the Water Odor Website. I was impressed by its wealth of information. I became concerned that the constand voltage poer supplies of competing ICCP systems could apply a voltage difference between the anode and tank so large that harmful electrochemical reactions could damage the baked enamel tank coating or so small that tank corrosion would not be prevented. The Water Tank Tec system has an intelligent poer supply that apparently can set the voltage and current based on the tank envioroment, so I ordered one.

After a difficult installation due to the original anode rod being very difficult to remove, the Water Tank Tec system has been working well. Attached is a photo showing the Water Tank Tec system down between the powered anode rod and the tank.

I am recommending the Water Tank Tec system to those concerned about their water heaters rusting out. Water odor is not a probem here. Matt, thanks for making the Water Tank Tec system available and supporting it so well!

Our company replaces over 300 water tanks per month. I buy from Water Tank Tec on a monthly basis. Our data base shows that since 2011, not one of our customers tanks have failed using this product. Last month Matt replaced a power supply that our customer had damaged. After contacting Matt to purchase a replacement, he sent me a new power supply free of charge and I had it in my hands within 3 days. I have never dealt with this type of quick action before. This is a solid product and a solid company.
