Recently had bad odor from bedroom with adjoining bathroom, tried to find out cause for days it only got worse. Finally someone inspected external drain & found a plastic bag with contents was wedged in pipe only allowing a trickle of water from toilets & waste to go through.
Since then outside smells gone but bedroom still has odor not as strong but bad enough so you don't want to sleep there.
Tried everything leaving windows open 24/7, washing down with bleach & disinfectant, leaving open container of baking soda, bunces of fresh rosemary.
I live in mediterranean so hot & sunny most of time.
At my wits end & any advice would be appreciated.
