Why does my house smell like sewer every time it rains?

Here I am again with an "old house" problem! Every time it rains hard my house smells like sewer and I am at a loss as to the cause. I put in a new sump pump, had the septic tank cleaned, and constantly check the two basement floor drains for any back-up, but nothing seems to stop the smell -- it goes away the day after the rain stops! I want to call a plumber, but would really like to have some idea as to what the problem might be before I get someone here so I can feel comfortable about what they say needs to be done. HELP!

  • Just seal off the sump pit. I had the septic leach issue and this works for now. Sewers coming in 2 years so I can wait. Great house and property .. worth it.

    I am having this problem. My landord has been out and dug up the septic tank to reveal that it was leaking. He had it repaired but the smell still remains. Is this smell toxic for my family?
