Install a Grundfos SQE series 1/2 HP variable frequency well pump with a CU301 VFD controller, stainless steel manifold and a WellExtrol 4.4 gallon buffering tank. Provide all labor and materials for the project including wire, pipe, new well seal and incidentals. Generally speaking, projects of this nature are completed n a time and materials basis and this proposal is for budgeting purposes. In my professional experience it is relatively accurate. Nevertheless, it is subject to change.
