There is a vent pipe inside the wall that goes up to the roof. So I can only assume that the black pipe sloping downward from the wall, as opposed to downward from the trap, is cause the problem. Any further comments you can provide would be much appreciated. Again, thank you for taking the time help me with this problem. I think you likely have something else going on. While the trap arm is going to be flooded because of the reverse slope, this would result in gases being less likely, not more likely.
Perhaps the vent is blocked? I actually ended up plumbing it into the clean out that is below the inlet that you see pictured. So the high Tee is the original drain? And the pipe that goes off horizontal above that is the vent because there is none inside the wall?
I want to solve without cutting up vanity too much. Seen all kinds of discussions as to whether S trap is ok, etc. I was thinking of raising the p trap so that its bottom is inside the cabinet and connecting down to the wall outlet with two 90 degree elbows.
Is that going to work, or is it the same as an S trap, with the same possible smell and venting problems? If I understand you correctly I suspect it would still amount to an S-trap.
My son and I remodeled his kitchen and have now run into a plumbing problem under his sink. The drain is unusually high which makes the installed P-trap high, too. The new basin sink is fairly deep and, to make matters worse, he has a dishwasher discharge connection on his tailpiece.
What other options could you recommend? Thanks in advance! Really appreciate all the info you have to share. I am trying to raise it up a bit and came up with this configuration. Is this the only thing wrong with my set up? Help, I have the following configuration and the smell coming from the drain is bad. I have checked and the trap is not drying out. If I take the p trap drain off I do notice that there is a slight buildup in the cap. Did I set something up wrong.
The pipe going right is for the double sink and the pipe in the back upper right is the vent pipe coming from the basement. What is the Tee abvoe the drain in the vent and where does the vent go to the right? The vent from the right comes up from the basement where there is a bathroom.
It goes into the wall and vents to the roof. Slope is correct. Triple checked it and even increased the slope slightly when I first noticed the odor. The smell is gone. I did 3 things. I lengthened the pipe from the first tee to trap, I replaced the trap with the cleanout to one without, and lengthened the trap arm a couple inches. It has been a few weeks and the smell has not come back. Thank you for your suggestions. Can p-traps be stacked? If there is one on the second floor and another inline in the basement do they cancel out each other?
Is this a problem? I have a similar issue in a new kitchen remodel. Is this acceptable? What are the alternative drain configurations I can suggest? Your email address will not be published. This site uses Akismet to reduce spam.
