Our front bathroom has a really bad sewage smell especially on hot days. When we try using the bathroom fan it gets worst, like it get circulated in the bathroom. We have no clogs cause both bathroom goes through the same drain. The vent on the roof is clear. What is causing this problem?

Any bubbles when you flush? Did this just start or has it been ongoing? City sewer or septic tank? If a septic tank is there a tank vent coming out of the ground? Back to you, Tom

We are on sewer line to the city. We've had this problem since we remodel and moved in last July. We notice the smell starting in September when school started. We are in the end of a cul de sac and the is a elementry school at the end of our street. We've had plumbers come and took a look. No leaks under the house and vents are all clear. They said it can be from the school, since we are in the end our bathroom is a vent. But we don't have the problem all the time. But lately it seems to be consistent. There is a little smell In the morning, the smell gets stronger as the day goes. The sorest smell is around 3 to 6 pm when it's hot. The smell gets better as the house cools down.

We have city sewer lines, no bubbling in the bathroom drains. The problem has been on going the last year since our remodel.
