Sump pumps often fail when the float switch gets stuck, either from debris or a misaligned mechanism, leading to continuous running or no activation. Power outages, improper sizing for the water load, and lack of regular cleaning also cause breakdowns. Even a tiny puncture in the discharge line can prevent proper water removal, while sediment buildup clogs the impeller over time.
