Dear Julia, • First Step... Please check if every sink, basin, shower and bath got probably fitted siphon (U bend) undernith. The reason it’s there is simply to stop the smell from sewer coming to the house. The water inside the siphon works as “plug” to stop the smell moving back. If any of those siphons will be empty or wrongly connected the smell from sewer will come to the house as no “plug” in place. • Second Step... Please check every outlet of each washing machine, dishwasher or similar equipment connected in the house. Each outlet of this “equipment” should go trough similar siphon/U bend as does the sink basin bath etc. Unless the hose coming out from e.g. dishwasher makes “U bend” itself so after finishing the cycle there is still some water in the hose providing “water plug” between the sewer and e.g. dishwasher • Third Step... If all above is in place then check all the waste pipe connections in the house. All waste pipes joints should have a rubber seal in good condition as it is not just stop the water leaks... it stops as well sewer gas leaks. Many times although there is no water leaks there “smell leaks” as the sill is still reasonable good for water tightness but not really for gas as water going down while the gas is going up and it can allow the smell escape trough old or not properly fitted rubber seals or badly done plastic welding. Please check all the toilet waste pipes as well. • Generally all sewers should have air vents. If they are not in place or blocked the smell will go up to the pipe instead of going “up to the sky”. Obviously find good reputable local plumber so he/she can do all the checks above. • If all above will be checked and in place and you still will experience bad smells please contact local council or building regulating body as the smell can come from outside pipes or some old connection not properly sealed in the inside wall. Hope that will resolve the problem. All the best in hunting the smelly monster ;) Regards, Rafal
