Hi,
I've had sewer odor in my basement for over a week now and can't seem to pinpoint the source. At certain times of the day the odor is stronger. I've checked all P traps in the house. All drains seem to function OK. I've smelled at the base of both toilets upstairs and basement, no odor. Ran hose water down all 3 roof plumbing vents and no backups all seemed to drain fine. The smell can be very sickening at times. I can't seem to find a drain in the basement. We bought the tri-Level in 1980 unfinished basement, but had the utility room finished with toilet [in basement]. I finished the rest of the basement with linoleum tiles and wouldn't have covered a drain. Do you suppose there could be a dryed up drain in the utility room a worker mistakenly covered with linoleum. Odor is sometimes present in the upstairs bathroom also and entry level livingroom. Help please!
