Technician Andrew was dispatched to Justin‘s home in regards to Sump pump float switch sticking when unit is in operation. Justin address concern for the operation of this new sump pump and float. Through evaluation was performed on this soft pump only today and found that secondary battery sump that was being reused did not have a check valve and primary pump was recirculating water through secondary pump not properly removing subsoil water and potentially flooding basement. Justin stated over our last rainy day (Friday ) he was in his basement the entire day with shop vac in hopes of preventing his basement from flooding due to this sump pump installation. Under warranty technician Andrew removed entire pump set up and replaced piping with new check valves (2) and offset fittings to allow for proper operation and to prevent water from splashing outside of sump crock. Justin was on site the entire process and explain to him that maintaining the system is paramount highly recommend
