We got Channel drain installed at the end of sloppy driveway. The Channel drain is connected to a Miter10 water pump which pumps out the water outside in upwards direction. Suddenly from last month the rain water from the Channel drain is not passing to the water pump area, instead its overflowing and flooding in garage. We had a look and can't find any visible blockage. Can we please get someone to come over to analyze the situation and give us a free quote.
