J . <br /> -40' <br /> 0 <br /> Exterior drain at base of stairs <br /> Solution A: Install backwater valve per Solution A in Problem Identified #1 and the floor <br /> drain will be protected by the backwater valve during surcharge events. All downspouts <br /> need to be disconnected from underground lines, and routed to splash blocks with this <br /> solution to avoid downspout water flooding the floor drain and other basement fixtures. <br /> Solution B: Install a sump pump that collects water from the floor drain and routes it to <br /> yard through a new drain line. <br /> 3) Downspouts are tied into side sewer (2 currently are).
