Most domestic sump pumps should be serviced annually, while commercial or high-use installations typically need checks every six months. Regular servicing reduces the risk of unexpected failure by identifying worn bearings, electrical faults, float switch problems and debris buildup before they cause stoppages. During a service our engineers will empty and clean the sump pit, test the pump under load, inspect discharge piping and non return valves, verify electrical supply and control settings, and replace or lubricate worn components as required. Routine maintenance also helps preserve manufacturer warranties, improves energy efficiency and extends the operational life of the pump system.
