I live in a 10 year-old house. Just in the past week, my faucet in the master bath has a sour, metallic smell for the initial 3-5 seconds of turning it on. It's a "one-knob" faucet. It only occurs from this faucet. My wife's faucet (3 feet away) is actually connected to the same water lines as my faucet, but she gets no odor. Any ideas about the cause?

There are three things you can do to try and remove the smell:

Remove the areator clean and bleach it.

Remove the faucet soak in Iron Out for 24 hours and reinstall.

Last, if the above does not work replace the faucet.

Safe plumbing brings life and health giving water into our homes, business, hospitals and takes away death and disease causing waste.

I saw this possibility in a previous post, so I tried covering the overflow hole.....same smell. I tried plugging the drain.....same smell. I even tried catching the initial water in a cup and taking it in another room before smelling.....same smell.

I'll try the recommendations from the other reply and see if that works.

Is it only the hot water or also the cold water? And does it go away after a few sections. Are you on a well.

Under certain circumstances with iron in the water and a harmless bacteria hot water can produce a sulfer smell.

From reading different complaints like yours it APPEARS that in some cases it will only produce a very small amount and that only collects at one place do to how the plumbing is aranged.

What it is is that the under sink feed line made in China is designed for chlorinated water. They assume everyone has city water. I have a well, no chlorine so after a while the feed line harbors bacteria. Box stores only sell these crappy lines so I have to replace them about once a year. This started when I replaced my bathroom vanity to a double sink. The rest of the house has older lines and no problems.

I have the same problem. We have well water (that is filtered) and it comes out odorless from every other outlet except the one faucet.

The pipes are all PVC, we don't have any water heaters and the smell is consistent: it lasts for about a minute when the faucet is opened after several hours (a day?) of non-use - and then it's fine for several hours (a day?) afterwards.

So what could be causing this build-up that gets cleared up after running the water for a minute? And how to fix it?

Any ideas gratefully received... :)

We have the same issue, but we do not have well water.

Have same issue too, one faucet with metallic odor at first after a little while of no use. I replaced the faucet and problem remains so it must be the line to the faucet :(

I have this same issue. 2 yr old house. It’s always been just our master bath faucets.
The other 3 faucets I. The house are fine.

I have the same problem with smell in one recently remodeled bathroom in my house. I am also on a well and am only getting the smell in the new bathroom. I am trying to understand if the problem is isolated to Moen products. As I understand they have put a plastic coating on the inside of their faucet products that apparently is not compatible with well water. Moen has replaced both my bathroom sink faucets side-by-side in the same bathroom under warranty. The problem has returned with the second set and they agreed to a full refund. (Unhappy Moen customer)

I have it in one sink, and it’s a relatively new faucet (2yrs old). It’s definitely from the faucet - and I’m not blaming Moen, as I have the exact faucet in a powder room, too, with no issues there. I’ve cleaned the drains, the supply lines were all replaced with the faucet install, and I have chlorinated water. So weird.

Same problem here except mine is coming from washing machine only. City water. It also isn't constant, it's sporadic but too often.


10:36PM | 10/04/18
I have the same issue. Smell is coming from bathroom faucet only. I just checked it and it's a Moen.


08:35AM | 10/11/18
what do you do for this problem?

I have the same issue only in one sink in my master bath on the second floor and only the cold water. It is a MOEN and I have the same MOEN fixture on the other side of my bathroom on the other sink with no smell there. Under my sink there is a metal t shaped pipe that both hot and cold water pipes come out of that has a little plastic cap on the top that is only on the smelly sink.

I'm having the same problem with a newly installed Delta faucet in the bathroom. We are on city water that is chlorinated. There is a sulphur odor from the hot water and it lasts for about 30 seconds when the water is run first thing in the morning. This was not a problem with the old faucet nor is it a problem with any other faucet in the house. The faucet was installed by a plumber last week. Suggestions?

One both of my feed lines has a metal spring inside them. As you can see, one is completely rusted as the other one isn't. I have well water and these Detla parts may not have been made to withstand well water. BTW, the rust odor/sulfur smell is terrible. I'm looking for a new solution to swap these out for plastic only. I'm guessing the spring is there to prevent line collapse.

On a well. Just replaced all the iron pipes with copper. Well has been shocked twice and removed the odor in the bathroom sink, but came back within a few weeks. Just this one faucet smells. We let the water run for a while and it goes away. Two year old faucet. just replaced the aerator. No change? Could it be the metals in the faucet?

We have a sulfur smell coming from a faucet in only one bathroom also. It happens when the water is first turned on and goes away in a minute. We are on a well and have had a whole house filter installed which did not help. Had a Plumber come over and was told the linings of the braided water supply lines from the valve to the faucet break down and take on the smell. Had both hot and cold lines replaced with Pex 1/4" SDR9 plastic line. It has been two weeks thus far and no smell. We'll see how this goes.

We have the same problem with a newly installed Delta faucet. We have well water and use a whole house system and have had a service call twice to address the problem. While our system did need servicing the first time, the second call showed no system issues and the service man suggested that it is the SHAPE of our faucet that is causing the problem by trapping water; the faucet is tall with about 7 inches tall and slightly U-shaped. He suggested removing the aerator to allow water to drain, but that causes the water to 'spit' as it comes out. He also noted that a stainless steel faucet would likely solve the problem. Has anyone else heard this / tried a stainless steel faucet to correct the problem?

Correction to above ~ it is a Kohler faucet with Ultra Glide Valve technology, not a Delta faucet.

My faucet with the bad smell is in my master bath. It is a Moen faucet and that is the only faucet that give the smell. I guess that I will have to replace that faucet. However, I did read in one post that they replaced their faucet and it was better for a while but the smell returned.

If you study the plumbing in your house, which may not really be possible if you didn't see it being built, you will find that the sink with the odor is the farthest, highest terminating point in your plumbing system from the supply line into the home.

Whether you have bad smell or not, you will probably notice that this sink always "foams" for a few seconds before solid water runs, especially if you haven't used it in a while, like being on vacation. That's because every microscopic bubble of air collects there, and is looking for an exit.

I am not an expert, nor do I truly know the answer to this question. But I can see lots of wild guessing going on here.

The brand of faucet you have will never be the cause of this problem, that's for certain.

My best guess is that not all of the "air" in your water is "air". A portion of it could be gases that can be corrosive or foul smelling. Chlorine gas would be a prime example. These gases collect at the terminal point of your plumbing system and that's where you smell or taste them. That's also going to be what's causing any corrosion damage to the lines.

So far, the most revealing evidence is the BV19705 who said he found the support spring inside his feed line corroded. I don't believe any water line should have exposed metal in it (other than copper or iron pipe). That would certainly put a foul taste in the water!

I am going to check my lines and see.
