Serviced Wayne 1/2 HP sump pump system @ Berkeley Lake property. Basin had accumulated significant silt/debris which I thoroughly cleaned out. Float mechanism was sticking occasionally - lubricated and tested repeatedly to ensure smooth operation. Discharge line clear with functional check valve. Battery backup system tested and operating as designed. Power connections secure with proper GFCI protection. System now cycling properly. Recommended quarterly checks given property's location in flood-prone area.
