Responded to service call for sump pump in crawlspace that was cycling on briefly then shutting off immediately. Upon arrival, found property without electricity, with pump attempting to operate on backup battery power. Inspected submersible pump installation in black plastic basin with Schedule 40 PVC discharge piping. Diagnosed pump failure due to inadequate power supply from backup battery system unable to sustain pump motor operation under load. Pump would energize momentarily but lacked sufficient voltage to maintain run cycle for effective water removal from basin. Verified electrical connections, tested pump functionality, and confirmed system required either restoration of main electrical service or replacement of backup battery to restore proper sump pump operation for crawlspace groundwater management.

Completed annual Gold Level planned maintenance on 8-year-old HVAC system during first visit of the service period.
