Very pleased.

It’s a no brainer if you remove the stink rod the odor stops. Virginian here, retired physics teacher with a 320 foot well in the hills. Very pleased with this product. Just purchased 2 more units for my good neigbors. First one purchased 3 years ago and I am solde, my water is clean when I fush the tank every 3 months. I would recommend!

I do not have hot water odor however a corrosion problem. This is our 4 unit from Matt. We could not removed the anode therefore installed the T system. Thanks Matt!

Very please with the product.

I purchase from Matt every month for our vacation rentals since 2015. I did have an issue with 3 units with a red light issue which were replaced at no cost. Their product works as they state. We have never replaced a tank since using this product.

Pleased with the results which is why I use this product. I dont have odor issues in the city. Never replaced a tank since I started using this product in 4 years.

I puchase dozens of these units from Matt every month, great customer service, outstanding product!

We had our new home built in 2021 and installed 2-40 gallon rheem gas water tanks. I searched for a product to get rid of the hot water odor and bought an amazon best seller product. After 9 months we started seeing black speks in our water with an unusual smell. I first tested the units with a volt meter which showed .7 amd .8 volts going to the anode. I pulled one unit out of the tank and found it had been leaking from the plastic top which soaked the insualltion around the tank and basically runining it. The other one was showing signs of chips falling off the anode. I compained to the seller and never heard a word. I spend $319.80 on their product and they did not have the curtosy to even offer me a replacement. I went back to the standard anode on the one tank, purchased a new tank and the odor came back.

I reviewed this products website and decided to buy one unit. When I tested this units voltage 6 months later it was 2.3 volts and the anode looked brand new. I purchased a second unit and have no odor at all now and I do feel I have proper corrosion protection voltage.

I wouild recomend this product.

Hello Mat, Just want to let you know this product worked great on my Hot Water Heater using well water. The installation was easy. I'm sending you a few pictures, but you really can't see much because everything went so well and is nice and neat. Thanks for a very good product. The first picture is of the original "1 1/16 plug on the old Anode rod. Bob A.

Thank you Matt for the system. We dont have an odor issue but a tank failure problem. I tested your power supply output like you brag about on your website. I will stand corrected it does work as fyou say it does. My odor is gone I expected this and the unit does change voltage when my soft water kicks in. great product. thnks Matt.

We are very satisfied with the purchase of your product. The sulfur smell is almost completely gone! Thank you Dan and Janet

We finished building our new house in a rural location in SW MI in late 2017 New well, with good water. About a year later, we started noticing a faint rotten egg smell in the shower. It seemed to be getting worse over time. Initially, I was thinking anerobic bacteria in our well. It was only the hot water that smelled though, so I started looking into different types of sacrificial anodes for the water heater. Mixed reviews on their effectiveness, especially for well water. I stumbled across the Water Odor site, and being an engineer, I was highly skeptical because it sounded too good to be true. Lots of very positive reviews though, so what the heck -- I'll try some snake oil! The device arrived quickly and was easy to install. I was even more skeptical, as how in the world could this tiny thing possibly do what the big anode couldn't?! By the next day, I couldn't believe the smell was almost totally gone. And as bad as my hearing and eyesight are, I have a nose like a bloodhound (and that's often not a good thing!). After a shower and using more hot water to flush the water heater tank, there was absolutely no detectable odor remaining. Fast forward 4 years, and it's still working great. Haven't had to touch it. I highly recommend this unit, and what have you got to lose? He will refund you if you aren't satisfied.

Thank you, Matt!

Hi Matt,

My installation was one hek of a project. Finished it on Thursday night. I took your advice and got a rotary tool and cut the steel vent hood (resulting in a lot of sparking!)...then had to finish cutting it with a mini hacksaw (you can see the cut out notch in the photo). Because I installed it the standard way, i didnt need to attach the ground wire to the side of the tank nor slide the vent cap over to make room for the anode bolt - which was the main purpose of notching out that opening in the steel.

As you can see from the one photo, the anode rod definitely needed replacement. I needed to use 18" breaker bar with a 4' steel cheater bar to break the epoxy seal. An impact wrench didnt work too well for me. One of the main reasons I used a powered anode rod (after discovering it on a google search) over a sacrificial one is that I am going to spray foam insulate inside the rim joists where the vent pipe comes out of...and after doing that, I wont be able to move the pipe due to the nature of the closed cell insulation. So, if i installed a sacrificial anode rod, i would have to move that pipe every 3-4yrs to check it or whatnot...which would not be possible with that type of insulation there. So now with this new anode rod (which will probably outlive the water heater tank) i wont need to do that and move ahead with insulating the rim joist in the summer. And if i need to buy a new water heater, i'll be sure the anode rod location is completely exposed and open to gain easy access to.

One benefit (that i didnt realize at the time when i bought it) resulting from this new sensor rod (in addition to stopping corrosion on the inside of the tank) is that I have noticed softer water after washing my hands which is related to removing the minerals associated with the old anode rod (aluminum and zinc) that circulated throughout the tank and hot water supply. So im very pleased with that.

The green light has been on steady since Thursday so Im happy its still working. There were some learning curves, but not too bad...especially for a first timer doing this. Great product though, glad i bought it.

Best Regards, Adam

I purchased this product hoping to stop my hot water odor and save my tank. The initial installation was easy with the instructions. The odor came back after 1 month. I contacted Matt and learned that my tank temperature was set way low (110) which allowed the bacteria to grow in the tank. I turned it up to 130 and wala the odor was gone the next day. I tested the voltage going into the anode when the installation was done. It was 4.2 volts which I though was a little high. The green led was flashing and I figured it was a bad unit. 2 hours later the voltage dropped to 2.8 volts and the led stoped. The next day it was 2.2 and the following day it was 2.9 and has pretty much stayed the same. Its an older tank 5 years so I figure it has some rust but my water is clear. This product works as advertised and thank you so much Matt for working with me on my email bombardment!

Hi Matt,

I have received the new kit and it is installed and working. Thank you so much for standing by your product. It is rare to experience this level of customer service anywhere. If there is a place I can provide positive reference feedback, please let me know.

We will be moving in late 2024. If you are still selling, I will he a repeat customer. I will also pass the word among my network.

I wish you and your family a gappy holiday.

Kind regards. Roger

The odor is gone matt, thank you!

I buy 35 a month from Matt, solid seller and product.

Message: RE: Order Number: #00625 (placed on November 3, 2019 The LED on the power supply turns red for a second when plugged in. It goes dark and no lights show after that. It worked fine with green LED since installed in 2019 until I noticed it off a week ago.

I installed the new power supply and the green light is back on. Thank you again for the excellent service. It's sadly rare these days.

Licensed plumber in Michigan City here. Our company has never had any issues with this product in the 3 years of dealing with Matt therefore I can recommend it.

I purchased this product 3 months ago and am pleased I know that the rod was my odor problem. I was more concerned about replacing my tanks in my home sicne I have 2 of them. 2.2 volts 2.8 and settled around 2.6 on an ao smith 40 gallon gas tank on installation. Great product Matt.
