Check to make sure that the drain hose loops as high as possible before coming back down to the disposer or branch tailpiece drain. If the drain hose just goes straight up to the drain connection, dirty water can seep back into the dishwasher.

I occasionally have a sewer gas smell near my washer. But after I run the washer, the smell will go away for a few days. What could the problem be?


Hi Joe

Is that pex pipe on the right your water supply to the washer?

Your sewer gas smell I believe can be eliminated by putting a P trap in the drain PVC line.

(EDIT)
Where the drain hose from the washer hooks into the PVC pipe is NOT airtight which would allow the sewer gas back into the laundry room!

(EDIT EDIT)
If there is a P-trap in your outflow pipe, the only place left for grey water to collect (and stink) would be between the washer and where the waste hose goes into the drain. We've had to use a little bit of bleach on occasion when we haven't used the washer for a bit.
Hope this helps

Rotten eggs smell


The smell is sewer gas coming back in the house from the sewer or septic tank ether from a dried out water trap in a floor or fixture drain, or from the roof vent, or a hole or separation in pipe or fitting. Like wax ring under toilet. First pore water down every drain to fill any trap that might have gone dry, then flush toilet or run washer or drain bath tub.This will displace gas in pipe and will cause the smell to increases if there is no smell then the problem is fixed if not check roof vent it may need a charcoal filter on top, There is no water trap on air vent on roof and is an open hole to the sewer or septic, The heating system in the winter or AC in summer will draw the gas inside from the vent.If it is the vent you should be able to smell it from outside. If all tests fails You will need to have a smoke test done. A smoker is set up outside and the line is filled with smoke and will show where gas is coming from. Also it might be a good ideal to check all gas fittings in case it is a gas leak.

Sewer smell drain


are there any floor drains in the room and an unused bathtub or shower? if so the water may have evaporated from the trap and allow the sewer gas smell. try pouring water into all the drains and see if it is still happening. more elaborate problem may be a broken vent stack in a wall.

Sewer gas smell in bathroom.


Sounds like you have an intermittently blocked vent pipe (the one that goes out through your roof). If there is gas pressure in the downstream sewer line and it can't get up through the vent, it could bubble up through your toilet or sinks. I would get up on the roof with a few jugs of powerful drain cleaner and dump them into your vents. You might also run a few dozen gallons of water down those vents after the drain cleaner has had time to work.
Good luck!

When machine pumps out the smell comes through the sink


All plumbing drains whether under a sink or the stand pipe drain, for a washer, are required by LAW to have a trap to prevent the sewer gases from entering a home.

Sewer gases are dangerous in many ways, not the least of which is the terrible smell. Sewer gas can build up and if allowed to accumulate near an appliance that operates on gas (LP or natural) can combust and cause a fire and/or an explosion.

Yes, if you can do the installation youself, do it ASAP, or contact a licensed plumber and have installed a proper drain trap for the sink and also make sure the drain that the washer is draining into, also has a trap in it.

This will have a profound impact on the smell and will help alleviate foul odors from your sewer lines.

Hope you found this Very Helpful and best regards!

Laundry room smells like rotten eggs


Does the sewer drain line have a trap at the bottom that prevents sewer gas from entering the room? If the smell seems to be coming from the washer itself, run a wash cycle empty with a cup of baking soda, detergent and hot water to clean the interior.

Fowl smell in bathroom


Fowl smells related to plumbing can have several causes. Here's a few potential issues that you can check. If none of them solve the problem you may need to call a plumber.

1) Look at your pedestal sink drain connection. Is there an an elbow connecting to your drain or a P Trap? A p trap is a pipe shaped like the letter "p" (hence the name) and it prevents sewer gas from rising into the bathroom. **sometimes an apprentice plumber puts in a pedestal without a p trap because they are fairly difficult to install, and ALL fixtures need P traps. If there is no P trap, then you need to put one in. It will be a tight space, but you may be able to do it yourself.

2) Do you have a floor drain? If so, your sink will need a trap primer at the drain. Or you can pour water into the drain from time to time before it evaporates from the trap

3) If the smell is more of a sulfur type smell and it appears from running water in other places in the house, then it could also be due the type of tank you have if you are on well water

My offhand guess is that number 1 is your issue.

Without further info, those are some of my best solutions so far, but if none of these are potential solutions, then make the following tests

1) close the door to the bathroom and leave it for an hour or two. Return to the room. Do you smell sewer smell? Is it in the entire room or more concentrated in a certain area? If you don't have a floor drain and its everywhere, there could be a missing P trap from a fixture, a lose toilet flange, a cracked drain pipe
2) without running water, smell your drain. Does it have a sewer smell? Then the P trap either is not present or you need to clean the drain with a drain cleaner due to a list of reasons
3) run water. does the sewer smell increase or does one suddenly appear. Is the smell more a different odor than sewer. See if it is the water itself. If so, check other places. If they do not have the smell then you may have recently installed your sink and there is some smell related to the new valve. Then you would need to use it some more until it disappears.

Check the top list, though because I really think you're just missing a P trap

Sewer breaks below the slab, an open pipe somewhere, some issue with the water supply, are among some other issues but that depends on the test

Try running citric acid (3 tablespoons) through.
You can get it from a drug store.
Or, run 1/2 cup vinegar through.
Do this in both the dish washer and the disposal.
After doing this try running some water into the disposal and then see if the next time you run the dishwasher if it still smells.
You could be having a problem with water not staying in the drain trap under your sink that is why if you run water and fill the trap, then you will find out if it was the dry trap that caused the smell from sewer gases backing up into the house trough the garbage disposal.

Bad smell


It sounds like your dishwasher does not have an air gap. Newer dishwashers come with an air gap installed, but they can be taken out. A quick fix for this is to:

Check the drain line under the kitchen sink. The drain line is supposed to run from the bottom of the cabinet, and run as high in the cabinet as you can get, (up to the bottom of the counter top) then connect the drain. This is called an air gap, and helps keep a little water in the drain line, which will prevent sewer gases from entering your dishwasher, and garbage disposal.



Please rate this solution.
