I am looking for information on an overhead system. I just bought a home and discovered during the rain that water comes up through the floor drains. Do you think an overhead sewer system would fix the problem? Also after the rain stopped (10 days worth) I find that every time a large load of clothes are washed the water comes up through the 2 floor drains. I am wondering if it is a back up in the main sewer line. I has been rodded three (3) times since May 29, 2007. Before the rain the washer did not make the drains overflow. Will another rodding through the floor drains stop that? I was told to try a standpipe, a sump pump a flood control system which is very expensive and even an overhead sewer to stop the problem. The last time it was rodded out to the street we did pull out tree roots. At this point I am at wits end on how to keep my basement dry. You can imagine with the rain we had in the Chicago Area a week ago everyday was an adventure. The water would drain but as soon as it started to rain again we had water. I was told to also move the downspouts from out of the main sewer line but it appears this has nothing to do with my washer causing the floor drains to overflow.
