Sewer Gas During Rain
My wife and I bought a home near coastal Alabama built in 1950. It has an extremely simple plumbing system (all in one wall) down, then out to the 2 septic tanks (1 original, 1 new, both connected) which are about 5 feet away from the house in the back yard. Both were pumped this past April.
Original cast iron vent pipe is still in place but under the house appears there's been conversion to PVC and everything looks pretty good. The underground drain is original iron. No draining problems, no gurgling, and no leaks/ moisture as far as I can see under the house.
Ok, when it's blue skies and sunshine, all is perfect; not a whiff of anything. When we get a hard rain, within a matter of 10 minutes, the bathroom smells like the bowels of hell. I mean, it's evil. As soon as the rain eases up, the smell is gone. Everything drains fine during and after the rain.
I don't smell odors outside or under the house except for one area at the corner of the home about 25' away from the tank... always in the same place, for some reason.
3 different plumbers don't know how this can happen but something must be done.
