So i am renting a house and we have been noticing a horrible smell when the AC comes on ( located in the basement). What we have come to find is a puddle about a half gallon worth collecting along the outside of the...lift station? which is located about a foot away from a sump pump that directs water out the side of the house through a house into the backyard. The landlord asked us to notify the city sewage dept, which came and checked the manholes which were cleared. Now trying to understand what is causing this?? We have soaked it up a few times and it continually comes back? My house smells like a port o potty. What is my landlord looking at as far as repairs. We take care of the house and plumbing so there shouldnt be any blockages due to our use. Thanks
