Our house is built on a slab. It is 30 years old. We have a septic tank and 300' of field lines. Three years ago, we had the field lines replaced. Lately every time it rains ( and sometimes when it doesn;t) a septic gas smell comes up through the master bathroom. A horrible smell that lasts!! We checked all the roof vents and they appear clean and clear. We pulled up the toilet and replaced the wax seal. We are completely out of ideas! That smell has to GO !! What can we do, is there anything else we can check?? Thank you for any help!!
I hope i can help,, You can take one cup size and dump some bleach down drains, thats should take care of the smells
