Patent ID: 8051873

Claim:
A method of installing a pumping system for replacement into an already installed wet well having a floor, comprising the steps of: pre-assembling a platform assembly by commonly mounting a pair of bent elbows having pump inlets and riser outlets on a planar base of an alignment platform having a platform centerline, and positioning the bent elbows equidistantly at opposite sides of the platform centerline; configuring the riser outlets to extend along longitudinal axes generally parallel to, and located at substantially equal distances away from, the platform centerline; overlying the wet well with an alignment cover having a cover centerline and a pair of riser clearance holes; configuring the riser clearance holes to extend through the cover equidistantly at opposite sides of the cover centerline at said substantially equal distances; passing a pair of upright risers through the riser clearance holes along longitudinal axes generally parallel to the cover centerline; aligning the longitudinal axes of the risers with the longitudinal axes of the riser outlets; connecting the risers to the aligned riser outlets; securing the pre-assembled platform assembly to the floor of the well after the risers are connected to the aligned riser outlets, and elevating the planar base of the alignment platform above, and generally parallel to, the floor; connecting a pair of submersible pumps inside the well to the pump inlets of the bent elbows by locating the pumps remotely from the alignment platform; and pumping waste water from the well though the bent elbows and the risers to outside the well by elevating intakes of the pumps above, and in non-overlapping relationship with, the planar base of the alignment platform to freely pump the waste water without interference from the alignment platform.
