Hoping someone can give me help with my fosse toutes eaux (septic tank). Bought our lovely house last year and whilst doing renovation last August noticed the fosse wasn't smelling good. Sitting outside in what will soon be a nice garden wasn't turning out to be a good experience! Before leaving at the end of August flushed in an activator to add microorganisms that may be missing which is supposed to work for up to 12 months.
Travelling back there tomorrow night but no internet. If fosse still smells bad, has anyone used something that will solve the problem? Any hints or tips would be useful.
