Customer stated that sewer ejection pump in basement was tripping breaker. Gave customer option of pulling pump and inspecting it. Customer agreed so went ahead and pulled pump. Once pump was pulled, found that there was no weep hole drilled and also that motor on pump was really hard to turn. Recommended to customer pump replaced and customer agreed. Furnish and installed new sewer ejection pump with new check valve. Tested and at this time pump was working as it should. Cleaned up work area.
