To begin annual maintenance on this Trenton homeowner's TripleSafe Sump Pump, Service Technician Jerry opens the airtight liner lid which has been developed to keep debris out of the sump pump pit. Once opened, Jerry proceeded to remove the primary cast-iron Zoeller pump along with the UltraSump Battery Backup Sump Pump and clean all of the components of these hard-working pumps, ensuring that their function remains in tip-top operating shape. Additionally, the liner is cleaned and sanitized before the sump pump system is reassembled as dirt and sediment can make its way into the liner with the ground water. Regular annual maintenance visits provide homeowners with continued, reliable system of wet basement solutions!
