My washer and dryer are in the basement. My sewer / waste line runs along the floor of the basement then goes through the wall and out to the main. The washer is at the end of the line. I have a 2" riser pipe coming out of the horizontal 3" waste line. Because there is no P trap on the riser or anywhere else on the waste line, I get sewer smells coming from the riser pipe. Can I add a P trap to the riser pipe to stop the smell or will the trap effect the drainage of the washing machine. Thanks in advance
