My bidet has a terrible sewer gas odor. It was installed a few years ago and has progressively gotten worse. I am now experiencing severe headaches and I think it may be from the gasses coming into my bedroom. I pulled up the bidet and found the drain has no p-trap. It just goes straight down into a 5 inch pipe that goes down into the ground. Is there a way to fix this without ripping up my floor and moving the sewer pipe? I can't move the bidet since there is only one place it will fit into my bathroom.

Are you sure that there is not an integral trap in the bidet? I have seen some with and some without. If there is no integral trap, I would buy one that does. It could also be from the overflow port on the bidet. Pour some bleach down it and run a brush down it and flush as best you can.

that depends on how much room you have between the bidet outlet and the big sewer pipe.
you can put a p-trap umder the bidet and send the drain to the back wall. you would have to take the pipe that goes straight down and angle it to the back wall as well.
it will mean opening up the floor and some of the wall.
if the big sewer pipe too close, you are out of luck.

ravi102769, that is a new one one me...i never knew they make those ???
if she can get one that would probably do it.

Sorry if I misled. What I meant was a trap inside or under the toilet, not molded into it. What kind of bidet has a five inch drain?



Edited 1 times.

I tried to post a picture but it wouldn't work. The bidet has a 1 1/4" drain pipe that goes straight down and connects to what looks like a 3 3/4" sewer pipe. The installer (most likely not a plumber) put some type of hard plastic web piece to connect the 1 1/4" drain pipe to the sewer pipe. When the shower is being used the sewer gasses get very strong. That's why I thought a p-trap would help. I could possibly take out the bidet's drain stopper and put in an s-trap. Think that would work?

Does an integral trap mean it has standing water like a toilet?

yes it does..

a full "S" trap while not legal under any code is better than no trap at all...

Many bidets are installed to a "pipe that goes straight down into the ground", because the trap is under the floor. You have to look down the pipe to see if there is water in the pipe which would indicate a trap. The only way to put a trap above the floor would be to run the pipe back into a pipe in the wall. I have never seen a bidet with an integral trap, and don't know how it could be done, since a bidet does NOT flush like a toilet.

from original post...
"I pulled up the bidet and found the drain has no p-trap. It just goes straight down into a 5 inch pipe that goes down into the ground."
there is no trap...

SInce it is NOT a "5 inch pipe going into the ground", we do NOT know what is under the ground.
