Pump Station Repair, Maintenance & Servicing

Repair the cause, not only the alarm

A high-level alarm or failed pump may be caused by the pump, controls, floats, valves, blockage, incoming flow or rising main. The whole station needs to be checked.

Alton Facility Services supports sewage, foul-water, surface-water and groundwater pump stations across Hampshire, Surrey, West Sussex, Berkshire and nearby areas.

Our engineers inspect the chamber, pumps, guide rails, lifting chains, level controls, electrical panel, alarms, valves, internal pipework and discharge arrangement before recommending repair or replacement.

Where a repair is economical, we aim to restore reliable operation and test the station under working conditions. Where equipment is obsolete or badly corroded, we provide a clear refurbishment or replacement recommendation.

For a completely new chamber and pumping system, use our package pump station design and installation page.

For specialist pump work, our sister company Alton Pumps provides pump station repair.

Breakdown and alarm investigation

Planned pump station maintenance

Routine servicing, testing and reporting to identify deterioration and reduce avoidable failures.

How we handle pump station faults

Triage the problem

We review the alarm, symptoms, site risk, previous reports, access and whether tanker support may be required.

Inspect and diagnose

The pump station, controls, level devices, valves, pipework and operating conditions are checked.

Repair, test and report

Agreed work is completed, the system is function-tested and any further maintenance or replacement needs are explained.

Common pump station faults

Pump stations can fail mechanically, electrically or because the chamber and pipework are not operating as intended.

A pump may be blocked, worn, incorrectly set, air-locked or unable to overcome the system head. Floats and probes can become fouled, control panels can fail, and non-return valves can stick or leak back into the chamber.

Repeated alarms should not be treated as a simple reset issue. Rising levels, excessive starts, long run times, odours or recurring trips can indicate a wider problem that needs investigation.

Issues we investigate

High-level alarms and rising chamber levels
Pump not starting, tripping or running continuously
Blocked or damaged sewage pumps
Float switch, probe and level-control faults
Control panel, contactor and alarm faults
Non-return valves, isolation valves and pipework defects

Servicing and refurbishment options

Planned maintenance helps find faults before they become a flooding or wastewater emergency.

A service can include operational checks, pump current and condition checks, float or probe testing, alarm verification, valve inspection, guide-rail and chain checks, chamber observations and a written record of defects.

Refurbishment may involve replacing pumps, controls, internal discharge pipework, valves, pedestals, guide rails, chains and level controls while retaining a serviceable chamber.

Typical repair and maintenance work

Float switch and level-probe replacement
Guide rails, pedestals and lifting chains

Pump station repair across West Sussex

AFS supports sewage and drainage pump stations in Chichester, Littlehampton, Petworth, Pulborough and surrounding West Sussex areas.

For an alarm or breakdown, provide the site postcode, alarm message, chamber level, number of pumps, control-panel details and any previous service report. Do not enter the chamber or attempt to handle sewage-contaminated equipment.

Where levels are rising, reduce incoming water use where practical. AFS will advise whether the first attendance should include electrical diagnosis, pump lifting equipment, tanker support or other site controls.

Pump Station Repair & Servicing FAQs

What should I do if the pump station alarm is sounding?

Reduce water use where practical, avoid opening or entering the chamber, and contact a pump station engineer. If levels are rising, tanker support may also be required.

Do you repair domestic and commercial pump stations?

Yes. AFS supports domestic, estate, commercial, care, education, industrial and managed-site pump stations where the access and scope are suitable.

Can you replace only the failed pumps?

Sometimes. The pump duty, guide-rail arrangement, controls, valves, chamber condition and cause of failure need to be checked before confirming a pump-only replacement.

How often should a pump station be serviced?

The frequency depends on usage, site risk, pump type and manufacturer guidance. Higher-risk commercial or sewage stations normally need more frequent planned checks than lightly used domestic systems.

Can you refurbish an old pump station?

Yes. Where the chamber remains serviceable, AFS can advise on pumps, controls, floats, guide rails, chains, valves and internal pipework refurbishment.

How much does pump station repair cost?

The cost depends on the fault, pump size and duty, chamber access, lifting requirements, controls, replacement parts, tanker support and testing. Send photographs, the site postcode and any service records for an informed attendance or quotation scope.
