Did a 25 year old two storey with finished basement. The 4 piece bath in the basement was nicely finished. Flushed the toilet and heard a pump come on. Looked in the linen closet and discovered an uncovered sump pump. No it was not a sewer pump! Then the smell! The sump was filled with water and floating toilet paper. The client gagged and ran outside for air. The best part: the sump went outside to a 4 inch plastic line laying on the ground. This line went into a municipal drain through a hammered hole. The drain emptied untreated into the river which went into Lake Erie. When you think that you have seen it all, something new comes up.
