This document provides the schematic and parts list for a public domain ramp pump design that can be built using off-the-shelf parts from home improvement stores. The design includes separate assemblies for the inflow check, inflow, outflow check, and ballast that can be screwed together for maintenance. A list of 25 required parts is provided along with the corresponding Lowe's SKU numbers for each part. Hydromissions does not guarantee the output or function of the unit as applications vary.
