I rent a house and there is a sewer leak and sewer flys all over the basement....Do I pay rent for the month or do you get any sort of compensation?

Sewer leak would be a breach of warranty of habitability. You may be entitled to a partial rent abatement for the conditions. You should write to the landlord explaining the conditions and the amount of time they existed and the impact on your occupancy. Request an abatement due to this and suggest an amount that you would find satisfactory. If you are unable to resolve this with your landlord an experienced landlord tenant attorney can help you to obtain a settlement.
