Rotten Egg/Sulphur Smell From 1 Year Old WH Tank
I looked at a vacant house today that had a 1 year old 80 gallon electric water heater tank. The circuit breaker to the tank was off and the agent said the house has been vacant for a few months. While there was no hot water, the water I ran on the hot side of the plumbing fixtures throughout the house was very pungent and had the rotten egg/sulphur smell. The smell did not go away no matter how much I ran the water but I'm pretty sure I didn't run 80 gallons worth.
I've run into this before but only with older water heaters which I assumed had corroded anode rods. I'm making mention of the stinky water in my report but I was wondering if anybody has an idea why this smell would be so strong in a 1 year old tank? Is it just a result of the house being vacant and the water sitting dormant in the tank and unheated? I don't see how the anode rod could be corroded already, assuming it is present inside the tank.

If the house is on a public water system, I would have to say something bad about the quality of life in your neighborhood. Good ball team though.

Re: Rotten Egg/Sulphur Smell From 1 Year Old WH Tank
Good stuff here Solutions to Stinky Water In Water Heaters
I also recommend turning the water heater up as high as it will go for a couple of days to kill the bacteria. If that works it is alot easier than all the others
Did you ask the broker if she farted?
That's always worth the price of admission just to see the look on her face

Nice link and info Wayne. I'll pass this along to my clients in addition my recommendation to have the tank serviced by a professional plumber.

Hi Nick,
I think what John is referring to, is that you will get the sulfer smell from well water.

Is this a private well? Did you run the cold water? If so, any sulfur odor? Running the cold water will help to determine if the sulpher is in the well. Sulphur in the well (not the same animal as bacteria in the water heater) can get expensive to treat if the concentrations are high. Since the house has been vacant for a while the sulphur odors have likely increased in concentration over time. If the supply system is used on a daily basis (i.e. the house is occupied) the occupants may not even notice the presence of sulphur because the supply system is 'ventilated' on a regular basis.

Not well water. Municipal public water system. And the odor only came out on the hot side of the plumbing fixtures.

I get the same smell from vacant house if they are on well water. When I test the well for bacteria it usely is contaiminated. A good dose of bleach takes care of it. If city water ,it may have stagnet in hot water tank

This is a normal occurrence with a water heater that has been shut down and the water not drained. The cold water reacts with the anode rod. This is not something that is caused with age. Nor is is something that is caused with the water to the home. Although you can get the rotten age smell from the water that is coming to the home. It will be from both the cold and hot water and will not go away. By running the hot water for about 30 to forty minutes with the hot water tank on. the smell will go away. Do not tell your people to call a plumber on this one. They will have to pay the plumbers fee and after the plumber tells them that all they will have to do is run the water you will not be looking good. And if they get the wrong person out there and he tells them they need to buy a new water heater. And for an 80 gallon water is over a thousand dollars. Think how you would feel.

Re: Rotten Egg/Sulphur Smell From 1 Year Old WH Tank
I hear you Bruce but if I were the buyer and I had a rotten egg smell coming out of all my plumbing fixtures, I think I'd want a professional plumber to make the call. Now my clients can do as they like. They can contact a plumber and let the plumber do his thing or they can undertake some of the DIY measures you and others have mentioned. But say they follow the DIY route on my recommendation (which is not my recommendation). Say the smell never goes away, they get frustrated with the situation and me for my recommendation, and they get a plumber who tells them what they want to hear (ie - they need a new tank even if they don't), who do you think they will set their sights on? I can't control unscrupulous tradesmen. All I can do is report what I find and put the rest in the buyer's hands.
Luckily, there are some other plumbing issues to be addressed so it's something a plumber can look at along with other items.

Re: Rotten Egg/Sulphur Smell From 1 Year Old WH Tank
Nick,
The odor is from mineral deposits that have collected on the Anode Rod that is inserted inside of the tank. This occurs when the tank sets idol for an extended period of time. There are occasions when the tank can be drained or purged, but in many cases, the Anode Rod may need to be replaced. Depending on the age of the tank, replacement may prove to be the most cost effective measure if purging the tank is not successful.

Re: Rotten Egg/Sulphur Smell From 1 Year Old WH Tank
ihave had the problem with my water heater before. i dump a cup of bleach directly into the water heater and wait one hour then empty it. run water thru it until the bleach smell disipates. it is a diy thing but it works every time.

Re: Rotten Egg/Sulphur Smell From 1 Year Old WH Tank
Like others I've had the same rotten egg smell, I removed the anode rod several years ago and suddenly this occurred. What worked for me was draining the heater & flushing it.
