The homeowner's sewage pump was not functioning properly. I removed the pump and cleaned it, hoping to find any debris causing the issue. Upon inspection, I discovered that the float had gotten stuck because whoever installed it had positioned it too close to the wall of the pit. I readjusted the float, re-piped the drainage line connected to the pump, and replaced the check valve and ball valve combo. After completing the repairs, I tested the system for leaks and sealed the lid with silicone.
