Washer smells like rotten eggs

[planethunter]

Hi everyone, I am to the forum and am in need of some advice for my situation. Our contractor installed our washer the way the pix show and we are now noticing that everytime we use the washer it smells like rotten eggs. After doing some research online, it looks like we need a p-trap so that the sewer smells go away properly? However, what do I do since the wall is already in place?

I presume you are talking about sewer odors.

Complain to your contractor immediately if it is fairly recent work. Maybe ask the city why they approved it that way?

When you get this fixed, your plumber will need to open the wall and fix things. That is usually not as drastic as it sounds.

Now if your hot water has sulfur smells from the taps, that would be something else.

Reach4, thanks for the info. Is the installation setup correct based on what the pix show? The drain tube that runs from the washer to the wall is at an upward grade so I am not sure if this is correct if it should be angled downward for proper drainage. Any other way that you can think of to determine if a p-trap is in place without having to open up the wall? We had a bad contractor and he is unreachable at this point.

What is under the red towel?

If there is a recess with a down pipe with water about 2 or 3 feet down, that would be normal.

I put the red towel there because the tube would come out from the recess with the movement of the water draining into the recess. Should the tube be connected to "something" in the recess?

There sometimes is a box with a hole in the bottom that accesses the standpipe.

If you don't have a vent pipe in the wall, you may be able to use an air admittance valve (AAV) https://terrylove.com/forums/showthread.php?20625-Washing-Machine-Drain

To figure out what you have, you might be able to probe down there with a snake or other probe.
