USE OF SOME RESERVE DRAINFIELDS MAY NECESSITATE PUMP AND/ OR SAND FILTER INSTALLATIONS.

THE ADDITION OF AN APPROVED EFFLUENT FILTER IN THE SEPTIC TANK IS REQUIRED TO ENSURE THAT SOLIDS DO NOT

PASS TO THE DRAINFIELD CAUSING PREMATURE DRAINFIELD FAILURE AND COSTLY REPAIR.

ALL REQUIRED TESTS SHALL BE SUCCESSFULLY RUN PRIOR TO CALLING JIM HUNTER & ASSOCIATES FOR FINAL

INSPECTION. ALL COMPONENTS, INCLUDING ALL TANK ACCESS LIDS MUST BE ACCESSIBLE FOR INSPECTION.

CONTRACTOR SHALL BE RESPONSIBLE FOR COST OF RETURN INSPECTIONS DUE TO FAILED TESTS OR INACCESSIBLE
