Solution: Divert outside floor drain to a separate pump that pumps to daylight in back <br /> yard. Pump would need to be able to handle between 30-40 gallons per minute at a <br /> minimum with a head of 10+ feet. <br /> Solution: Install a larger capacity grinder pump that can overcome both the internal <br /> plumbing configuration head (approximately 10 feet) on the system and the potential <br /> surcharge head (no more than 6-8 feet) on the sewer line. Due to the location of the <br /> existing grinder pump the length of pipe (approximately 70-80 feet) it has to run should <br /> also be taken into account. <br /> 2) Landscaping at back stairway to basement causes funneling of surface water from <br /> back yard to drain down towards the floor drain adding a large volume of water to the <br /> system. <br /> Solution: Adjust landscaping to ensure surface water does not run down the stairs, but <br /> is diverted away from the house and foundation. <br /> As-Built of Sewer and Plumbing <br /> See attached drawing. <br /> Comments <br /> NOTE: Sump/Grinder pumps work off of electricity and during a storm event power may <br /> be lost causing the pump to stop working and potentially flood the basement. <br /> To help prevent major flooding ensure that all landscaping surrounding the back patio <br /> area is sloped away from this area to reduce the volume of water that would be required <br /> to be pumped out. <br /> Additional Photos and Descriptions <br />
