What to Do When Your Water Smells Like Rotten Eggs

Article Image


Does your water smell like rotten eggs? If you are having problems with the way your well water smells, here are some things you can do to fix it.

If your water smells like rotten eggs, the odor is usually caused by the levels of sulphur that can be found in your home’s water supply. As the water comes out of the faucet, the sulphur hits the air, becomes oxidized, turns into hydrogen sulfide gas, and that’s when you get that terrible smell.

Not only can that smell be a sign that there are unwanted elements in your family’s water, but it can also cause am embarrassing and unpleasant smell for your family and your visitors. You don’t want your guests - or yourself - feeling dirtier when they get out of the shower than they did when they got in.

That rotten egg smell is not usually an indication that your water is unsafe to drink, but it is an indication that your water is not the purest that it can be.

How to Fix That Rotten Egg Smell in Your Water?

 Water Rotten Egg Smell

Nobody likes eggs in their water, unless – of course - they are actually trying to cook eggs. And absolutely nobody likes rotten eggs, in and out of their water. So, having a rotten egg smell accost you every time you turn on a tap is unpleasant and unappetizing.

So how do you fix it?  

The first thing you want to figure it is where the rotten egg smell is coming from.

For example, if you only experience the smell when using the hot water, the source of the issue is likely coming from your hot water heater and not the main water supply.

Also, of the smell only seems to be noticeable at one sink in the home, but not others, the issue could be with a buildup of Sulphur residue in the drain.

However, if you get that rotten egg smell with both your cold and hot water throughout the house, then there are likely high levels of Sulphur in your water supply that needs to be addressed before you can get rid of that smell.  

Rotten Egg Smell with Hot Water Only

If it is only your hot water that smells like rotten eggs, this is most often caused by an issue with your water heater. The best way to fix this is to contact a licenses hot water heater maintenance company or by replacing your hot water tank.

It's possible that your old hot water heater has become overloaded with mineral deposits from your home's water supply and is now at the point where it needs to be repaired or replaced. 

If this is the case, upgrading your water heater could not only get rid of that terrible rotten egg smell, but could also end up saving you money on your monthly utility bills

Rotten Egg Smell from Treated Cold Water

If your cold water also smells like rotten eggs, check to make sure it has the same smell before an after any other water treatment systems you have in place. For example, if you have an old water softener in your home, it could be the source of the problem. Check the treated and untreated water. In most cases, outside water is left untreated, so you can check the smell of your water from the outside lines to find out of the issue is the water supply or something that happens after the water enters your home’s water distribution systems.

If you do have a Sulphur bacteria build-up in your water softener, consider cleaning out the brine tank first and then replacing the softener media if that does not fix the issue.

If neither of those work, you might want to consider investing in a new water softener .

Rotten Egg Smell Only at One Sink

If you notice the rotten egg smell only in the master bathroom sink, but nowhere else in the house, it is likely coming from the drain and not the water. When you run the water to brush your teeth, enough water will go down the drain to stir up the accumulated contaminants and gas, which will release the smell upwards and into your face.

If you take the drain trap apart, thoroughly clean it, and put it back into place, you should notice the smell go away immediately.

Rotten Egg Smell from All Water, Everywhere

If the smell is strong when either the hot or cold faucets are turned on, anywhere in the house you most likely have an accumulation of sulphur bacteria in your home’s water supply. This is most common with homes on a well water system.  

You may notice that the rotten egg smell gets better or goes away after the water has run for a while. This does not mean the problem is clearing itself up. You may also notice that the smell seems to fade over time, but that is more likely that you’ve simply become accustomed to the smell.

If you have too much Sulphur in your water supply, the best way to get rid of that is by installing an Iron and Sulphur removal system which can effectively remove those contaminants before they reach your taps.

Not only can this help improve the smell and taste of your water, but it will also help reduce any damage or corrosion to your pipes as well as discoloration to your silverware and plumbing fixtures.

FOC and FOB Chemical Free Iron and Sulphur filters do not contain any filter cartridges to replace or chemicals or salt to add.  This method is the easiest and most inexpensive way to significantly reduce iron content from your family’s household water.  This process is so successful that you will actually forget that you once had Iron and Sulphur in your water

The Four Step Process for Fixing That Rotten Egg Smell

Fixing the Water Rotten Egg Smell

If you are experiencing that terrible rotten egg smell with your water, here is a simple process to identify and fix the issues.

  1. Identify the Source – Is the smell in your hot water? Your cold water? Or both?

  2. Find The Cause – Determine if the source water is contaminated, or if an existing water appliance is causing the issue.

  3. Clean, Repair, or Replace Water Treatment Systems – This includes your water heater, as well as any water softeners or reverse osmosis systems you have in place.

  4. Install an Effective Filtration System - Iron and Sulphur filtration from water can be accomplished many ways. We feature and recommend chemical free oxidation using, you guessed it, air!

Hopefully, you can get rid of that rotten egg smell in your water and only ever have to deal with a smell like that when you accidentally crack open a rotten egg.

Remember, bad smells are not only unpleasant, but could be a sign of a bigger problem. Never ignore any kind of unpleasant smell when it comes to your family's drinking water. Although not all of them indicate a potential health risk, it's always better safe than sorry.
