    Default Rotten Egg Smell From Faucets Cold Water

    We just moved into our new Old House and noticed a rotten egg smell coming from the kitchen sink, we did some investigating and found:

    1. Cold Water only has the smell, the hot water does not smell at all (From what I've read usually the hot water smells worse)

    2. The kitchen and Main bathroom sink and toilet are the only ones that smell, the master bath is fine as is the Shower and Laundry that are in the Main bath.

    3. The house has a water softener that supposedly is a whole house system.

    4. The house had been vacant for about a month before we moved in I have not checked with the previous occupant to see if she noticed the smell, but could if that info would help.

    5. Well Water

    We want to get rid of the smell (it is really grossing me out!) but have no idea where to begin. It is definately the water and not the drain. I have read that it could be the water softener, hot water heater, pipe or well. I'm assuming its not the hot water heater since the hot water doesnt smell. So I dont know where to go next? Any help would be great! Thanks

    That aroma is usually associated with high sulfur content in the water. There are water purification systems that will remove the odor and other problems.
    I suffer from CDO ... Its like OCD, but in alphabetical order, LIKE IT SHOULD BE!!!

    Let me just add this:

    Depending on the amount of sulfur in your water, clorine can solve the problem. For stubborn sulfur, a whole house catalytic carbon filter will be needed.

    This smell could be coming from a few places.

    1) The water softener

    Do you have a faucet that is before the softener? If so check to see if you have the smell there. If the smell is there you know its before the faucet, if not then you know its after the faucet.

    2) Water psi tank

    Is your tank a bladder style tank? If so check the date on the tank. From my experience the bladder tanks have a life span of about 5-7 years. When they go bad they can cause a rotten egg smell. (I see this on a weekly basis) If its bad I suggest going with a galvanized tank.

    3) The well

    If its this you can fix with different means that we can get into later.

    First things first when your on well water the well needs to be treated with chlorine or bleach there is a process find out when the last time this was done or if ever done, I would check that first this is most likely the cause sometimes the Anode rod in the water heater can also cause sulfur smells and just because the hot doesn't smell doesn't mean its not the water heater because the water could be causing back flow into the cold side and you could always by pass the softener and see if the smell goes away it may be all of the above but more than likely the well water just needs to be treated.

    Wink Re: Rotten Egg Smell From Faucets Cold Water

    We moved into this house in Oct 2004. There also was the awful rotten egg smell. We have a well and had the water tested and found high levels of iron in our water. What to do? Spend the money digging a new well that may have the same problem or spend on a system to clear the water. We got the system. I live in Western Pa so I went with Gordon Bros. They cleared up the problem. I was hoping not to have to deal with having to add anything, but I do have to add chlorine and water to a small tank whenever the water drops to a certain level. I also wanted the water to be potable so there are two small tanks with some kind of charcoal. We do have a large intake kind of tank that needs to be flushed from the bottom every time I add the chlorine. That water is a thick looking rusty red color. I am soo thankful to have this system. We ruined so many clothes, and the toilet and sink were stained also. We tried shocking the well to no avail first. I would just have someone come in that knows their stuff and be done with it.
