W <br /> Since the two pumps will alternate, a check valve is to be installed on each 2" discharge line from <br /> each pump before connection into a single 2" line. A reducer will be used to connect this 2" <br /> discharge line to an "end-feed" 4" tightline manifold that is to be capped at the opposite end. <br /> Three, 4" dia. perforated leachline pipes are to "Tee"connect to this manifold and will allow the <br /> distribution of effluent through these three pipes, with the perforations set at the 4 o'clock and <br /> 8 o'clock positions. The pipes are to be capped at the ends and equally spaced in a 25 ft N-S x 30 <br /> ft E-W = 750 sf filter bed filter bed. Twelve inches of drain rock are to be placed below the pipes <br /> and 2" of drain rock above the pipes, then covered with filter fabric. Backfill with excavated soil <br /> to a depth of 6" over the filter fabric to match surrounding grade. <br /> Attached to this document, is a Duplex Pump Station from Septic Solutions, Inc. to give additional <br /> detail of the proposed system.
