Sump pump repair covers the inspection, refurbishment or replacement of a submersible pump installed in a sump pit to handle groundwater or surface water ingress in basements, lift pits and external chambers. Common faults include burnt-out motors, blocked impellers, failed float switches and corroded electrical connections in damp pits. Replacement units must be sized for the duty head and flow, with cable routing protected against snagging and water ingress. Electrical work must comply with BS 7671 (IET Wiring Regulations) and is normally undertaken by a NICEIC or NAPIT registered contractor. London basement conversions in low-lying areas often rely on dual pump arrangements with mains-failure battery back-up, given the consequences of pump failure during heavy rainfall.
