Side Sewer material: PVC <br /> Depth of side sewer 10ft from house: 4' <br /> DVD made of side sewer: Yes <br /> Any additional comments: <br /> • There is a floor drain at the back door (to the basement) which is tied into the <br /> down spout drain lines. <br /> Problems Identified <br /> 1) This home does not currently have a backwater valve to prevent backups during high <br /> flow surcharge events. <br /> Solution: <br /> Install backwater valve. See attached site drainage and plumbing sketch for proposed <br /> location. <br /> 2) Drain at back door to basement, is connected to down spouts. After installation of the <br /> Back Water Valve the site drainage and sewer has the potential to back up through this <br /> drain and flood the house through the back door. <br /> • <br /> 4r. <br /> -q2H <br /> �, till 6 <br /> Drain outside of door to basement <br /> Solution: <br /> Remove the 3 down spouts connected to the sewer and place the Back Water Valve <br /> downstream of the connection for the floor drain. This will protect the floor drain from a <br /> surcharge event. The down spouts must be disconnected, otherwise during a <br /> surcharge event the water from the downspouts will be forced up through the floor and <br /> into the basement. <br /> 3) 3 Downspouts are tied into the side sewer. This causes increased flow in the side <br /> sewer. <br /> Solution: Disconnect downspouts, extend 3' or more from foundation, and discharge to <br /> splash block. Ensure portion of yard that splash blocks discharge to slopes away from <br /> house. <br />
