Installing appropriate corrosion protection inside the water heater can prevent the chemical reaction from occurring inside.

Cold water smells like rotten eggs

If your water smells like rotten eggs only when you turn on the cold faucets, the reason is due to sulfate-reducing bacteria. The environment that leads to poor aeration and corrosion will promote the growth of sulfate-reducing bacteria. If you provide corrosion protection, you will be able to kill sulfur bacteria and remove the rotten egg smell from your cold water supply.

Hot water smells like rotten eggs

The hot water supply that has a rotten egg smell is due to the chemical reactions in the water heater. There is a metal rod called the ‘Anode rod’ inside hot water heaters to provide corrosion protection. This Anode rod could be either a magnesium anode rod or an aluminum rod. When the magnesium anode reacts with sulfates in the water, it will generate a hydrogen sulfide odor. The water heater temperature or the warm environment inside the heater supports the sulfur bacteria growth. You can reach out to a trained boiler inspector to sort out this problem.

If you are getting a rotten egg smell when you turn on the hot tap and the cold faucets, you must be cautious as there could be a serious problem. If you smell rotten eggs in both hot and cold water, the reason is hydrogen sulfide gas in the entire water supply. Sulfur bacteria produce hydrogen sulfide gas as the result of feeding on the sulfate content in the water.

When the hydrogen sulfide gas gets trapped in the underground water supply, the entire water supply or the building’s water supply will promote the bacteria’s growth.

What causes high sulfur in water?

Too much sulfur in the water supply is a result of high levels of hydrogen sulfide gas. When the sulfur bacteria in the water supply is on the higher side the rotten egg smell will emanate. To remove hydrogen sulfide gas and its odor, you must kill sulfur bacteria and the dead bacteria present in the water supply.

What are the long-term effects of drinking sulfur water?

What are the long term effects of drinking sulfur water?

The long-term effects of using tap water and drinking water that has sulfur in them are many. While some might lead to serious complications in health, others might not.

Extended use of sulfur water can cause black stains in silverware and plumbing fixtures due to corrosion.

However, it has been said that despite the strong rotten egg odor in drinking water, there is not a problem of immediate concern. It is a serious issue if the sulfur odor or rotten egg odor is from other contaminants, such as sewage. If sewage water or other harmful contaminants have penetrated into the building’s water supply, well and plumbing system, or distribution system, it must be addressed at the earliest.

What are the symptoms of high sulfur levels?

What are the symptoms of high sulfur levels?

If you continue to intake water with too much sulfur, there are other symptoms that will begin to show up in the body and in the things the water comes in contact with. Once you begin to notice the following signs and symptoms, you must watch out if there is too much sulfur in the water that you use.

Color

If you notice that the silverware and plumbing fixtures in your home are changing in color it is a clear indicator that there is too much sulfur bacteria in the water.

Pipe

Did you know that high levels of sulfur content in the water will corrode metals? If you fail to tackle the sulfur content in the water, you will begin to experience problems in the plumbing system as iron, steel, and copper metals begin to experience corrosion.

Taste

Along with sulfur-smelling water, you will also notice that there is a change in the taste of the water.

Stomach issues

With increased intake of sulfur, you must know that this can result in frequent stomach issues like dysentery and diarrhea. This can turn into serious complications in infants, young children, and animals.

Dehydration

Too much sulfur and the stomach issues that it paves the way to will eventually lead to dehydration as well (as a result of diarrhea).

Experts suggest that any of the above signs must not be neglected. Act promptly by taking measures to prohibit sulfur infiltration into your water supply. Do what is required to get rid of the sulfur damage that is already done and to prevent further hazards.

Frequently Asked Questions:

1. Does Brita remove sulfur?

No. Brita pitcher filters are not certified to remove sulfur or sulfates from the water. However, you can use Brita pitcher filters to remove hydrogen sulfide concentrations in small amounts from the water. The carbon filter built into the Brita pitcher will facilitate this.

2. Does hard water cause a sulfur smell?

The sulfur smell in hard water can be a result of the hydrogen sulfide gas or the sulfur bacteria that is reacting with magnesium. The scent could also be from high concentrations of iron in the water.

3. What does it mean when your tap water smells bad?

The bad smell that comes from the water coming from the hot tap or the cold faucets can be a result of hydrogen sulfide gas from the sulfur bacteria, sewage, or corrosion.

4. Can you drink water with hydrogen sulfide in it?

Drinking water that has high levels of hydrogen sulfide concentrations in it is hazardous to health in the long run.

5. Will bleach help a smelly sink drain?

Yes. Liquid chlorine bleach solution is effective in removing unpleasant odors from a clogged sink drain. Pour in a cap full of bleach and follow it up with a jet of hot water for a minute or two. This will remove all the unpleasant smell that emanates from the drain immediately. You must remember that this is not helpful ok clear the drain, but only to get rid of the smell (since the liquid bleach cannot disintegrate soap scum, hair, and another blockage).

6. Is hydrogen sulfide cancerous?

We do not have any conclusive studies or research on the cancerous effect of hydrogen sulfide on humans or animals.

7. Will a water softener remove the sulfur smell?

No. Any regular water softener solution or unit that does not have a separate sulfur bacteria filter will not have an effect on sulfur-smelling water.
